C95400 Aluminum Bronze Casting, AB1 Grade Bronze Casting

Cable Glands India is a specialist C95400 aluminum bronze casting manufacturer, foundry and exporter based in Jamnagar, Gujarat, India, supplying AB1 grade bronze castings to buyers in the United Kingdom, United States, Europe, Australia and Canada. C95400 — also written as CDA 954, alloy 9C, or the nickel‑free aluminium bronze CuAl10Fe3 — is the general‑engineering workhorse of the aluminium bronze family, and we cast it to ASTM B148, ASTM B505, ASTM B271 and ASTM B806 in as‑cast (M01) and heat‑treated (TQ50) tempers.

We supply C95400 castings as sand cast, shell moulded, gravity die cast, centrifugally cast and continuous cast components, rough machined or fully finished to customer drawing, with EN 10204 3.1 material test certificates as standard.

What Is C95400 Aluminium Bronze?

C95400 is a binary‑plus‑iron aluminium bronze containing nominally 11% aluminium and 4% iron in a copper matrix, with nickel restricted to 1.5% maximum. The aluminium forms a tenacious, self‑healing alumina (Al₂O₃) film that gives the alloy its corrosion resistance, while the iron precipitates as finely dispersed kappa phase that refines the grain and raises hardness and wear resistance.

Because it contains no deliberate nickel addition, C95400 is significantly more economical than the nickel aluminium bronzes C95500 and C95800, yet it still delivers roughly twice the strength of leaded tin bronzes such as C83600 or C93200. It is the default specification wherever high strength, good wear resistance and moderate corrosion resistance are required at sensible cost — gears, bushings, wear plates, valve components, pump housings and non‑sparking tooling.

In British practice the equivalent casting alloy is BS 1400 AB1, a nickel‑free CuAl10Fe3 aluminium bronze. AB1 and C95400 are widely cross‑specified by procurement teams and are metallurgically very close; C95400 sits at the higher end of the aluminium and iron ranges. Where a certified AB1 chemistry is mandated we pour to the BS 1400 limits and report both designations on the test certificate.

Key Properties of C95400 / AB1 Grade Castings

• High tensile strength — 515 N/mm² minimum as‑cast, 620 N/mm² minimum after TQ50 heat treatment
• Excellent wear, galling and abrasion resistance under heavy load
• Good resistance to seawater, brine, mine water, dilute acids and industrial atmospheres
• High resistance to cavitation and erosion‑corrosion in flowing water
• Non‑sparking — suitable for ATEX and hazardous‑area tooling and fittings
• Retains useful strength to approximately 250 °C
• Non‑magnetic (relative permeability below 1.05 in the as‑cast condition)
• Low friction coefficient against hardened steel, tolerant of marginal lubrication
• Readily weldable by MIG and TIG using matching aluminium bronze filler

C95400 Chemical Composition (ASTM B148 / ASTM B505)

Copper plus the sum of the named elements shall be 99.5% minimum. Every heat is verified on a calibrated optical emission spectrometer before pouring, and the ladle analysis is reported on the material test certificate.

For comparison, BS 1400 AB1 is specified nominally as CuAl10Fe3 — approximately 8.5–10.5% aluminium, 1.5–3.5% iron, nickel 1.0% max and manganese 1.0% max, balance copper. Buyers who require strict AB1 conformance should state BS 1400 AB1 on the purchase order so that the melt is aimed at the BS window rather than the ASTM window.

C95400 Mechanical Properties

Values are for separately cast test bars to ASTM B148. Properties in the body of a heavy section casting are typically 5–15% lower because of slower solidification and coarser grain; we quote section‑specific expectations at enquiry stage for wall thicknesses above 50 mm.

C95400 International Equivalent Grades

Cross‑references are given for guidance. Composition windows differ slightly between standards, so please confirm the governing specification on your order and we will pour and certify to that specification.

C95400 vs C95200 vs C95500 vs C95800 — Which Aluminium Bronze Should You Specify?

Rule of thumb: specify C95400 for mechanical duty (load, wear, galling) in fresh water, mild chemical or atmospheric service. Step up to C95500 when you need more strength, and to C95800 when continuous seawater immersion and cathodic protection compatibility govern the design. Choose C95600 when machinability and electrical connector duty matter more than peak strength.

Heat Treatment of C95400 (TQ50 Temper)

C95400 responds to quench‑and‑temper heat treatment in the same way as a low‑alloy steel, because the beta phase present at high temperature can be retained and then decomposed in a controlled manner.

• Solution treatment: heat uniformly to 815–870 °C (1500–1600 °F) and soak one hour per 25 mm of section
• Quench: water quench to retain the beta phase
• Temper: re‑heat to 565–620 °C (1050–1150 °F), hold two hours minimum, then air cool
• Result: tensile strength rises from 515 to 620 N/mm² minimum and hardness from 150 to 190 HB, with elongation reducing to 6% minimum

An intermediate temper anneal at 600–650 °C followed by furnace cooling is also used to stabilise the microstructure of thick sections, relieve casting stress before final machining and improve dimensional stability. For components that will operate between 250 °C and 400 °C, a stabilising anneal is strongly recommended to avoid the slow eutectoid decomposition that can embrittle untreated aluminium bronze in service.

Casting Processes for C95400 Bronze Components

Sand Casting

Our green sand and chemically bonded no‑bake lines produce C95400 castings from a few hundred grams to several hundred kilograms. Aluminium bronze is poured through carefully designed bottom‑gated, filtered running systems to prevent the oxide films that cause the characteristic aluminium bronze defects. Typical products: pump housings, valve bodies, wear plates, bearing housings and gear blanks.

Centrifugal Casting

Horizontal and vertical centrifugal casting produces dense, directionally solidified C95400 tubes, sleeves, bushings, wear rings and gear rims with no centreline porosity. The impurity‑rich inner skin is machined away, giving an exceptionally clean bearing surface. Standard sizes run from 40 mm to 900 mm outside diameter.

Gravity Die Casting (Permanent Mould)

For repeat production runs the faster cooling rate of a permanent mould refines the kappa phase distribution and lifts mechanical properties above the equivalent sand casting, while reducing machining allowance. Cast to ASTM B806. Ideal for flanges, brackets, small gear blanks and industrial fittings.

Shell Moulding & Investment Casting

Where surface finish and dimensional accuracy matter — impellers, valve trim, complex non‑sparking tooling — shell moulding and lost wax investment casting deliver finishes of Ra 3.2–6.3 µm and tighter tolerances, cutting machining cost on intricate parts.

Continuous Casting

Continuous cast C95400 bar, tube and hollow to ASTM B505 provides a uniform, fine‑grained structure ideal for machined bushings, thrust washers and wear strips produced from stock rather than from a pattern.

Machining, Welding & Fabrication Guidance

• Machining: rating 60 relative to free‑cutting brass. Use rigid setups, positive rake carbide (K10/K20) or coated carbide, surface speed 60–120 m/min, generous feed and copious coolant. The alloy work hardens if the tool dwells, so avoid rubbing and light finishing cuts.
• Grinding: free grinding with silicon carbide wheels; keep the wheel dressed to prevent loading.
• Welding: readily welded by GTAW (TIG) and GMAW (MIG) with matching ERCuAl‑A2 filler. Preheat 150–200 °C for heavy sections, keep interpass temperature below 250 °C and clean the oxide film mechanically before each pass. Post‑weld stress relief at 600 °C is advised for pressure‑retaining parts.
• Brazing and soldering: difficult because of the tenacious alumina film; mechanical joints or welding are preferred.
• Galvanic compatibility: C95400 sits close to austenitic stainless steel and copper‑nickel in the galvanic series and pairs well with them. Avoid direct coupling to aluminium, zinc or plain carbon steel in an electrolyte without isolation.
• Surface treatment: supplied as‑cast, shot blasted, vibratory finished, machined or, on request, with cathodic protection provisions for immersed service.

Frequently Asked Questions About C95400 Aluminum Bronze Casting

What is the price of C95400 aluminum bronze casting?

Our indicative price for C95400 / AB1 grade bronze castings is US$ 15.60 per Kg, FOB India, for plain as‑cast components at a minimum order quantity of 50 Kg. The final price depends on casting weight, geometry, pattern cost, machining content, order volume and prevailing LME copper and aluminium prices.

Is C95400 the same as AB1?

They are the closest commercial equivalents but not chemically identical. C95400 is the American UNS designation (ASTM B148, nominally Cu‑11Al‑4Fe) while AB1 is the British BS 1400 designation for a nickel‑free CuAl10Fe3 aluminium bronze with a slightly lower aluminium and iron window. Both are nickel‑free general engineering aluminium bronzes and are routinely cross‑specified. We can pour to either specification and will certify to whichever standard your order names.

What is the difference between C95400 and C95500?

C95500 contains 3.0–5.5% nickel, which raises minimum as‑cast tensile strength from 515 to 620 N/mm² and substantially improves seawater and cavitation resistance. C95400 is nickel‑free, more economical and easier to machine, and is preferred for gears, bushings and wear parts where mechanical duty rather than aggressive corrosion governs the design.

Is C95400 aluminum bronze non‑sparking?

Yes. C95400 is classified as a non‑sparking copper alloy and is widely used for hand tools, tooling inserts, fittings and enclosure hardware in ATEX and other hazardous‑area installations in oil, gas, petrochemical, grain handling and mining environments.

Can C95400 castings be welded?

Yes. C95400 is readily welded by TIG and MIG using matching ERCuAl‑A2 aluminium bronze filler. Preheat heavy sections to 150–200 °C, remove the alumina film mechanically before each pass, keep interpass temperature below 250 °C and stress relieve at approximately 600 °C afterwards for pressure‑retaining components.

What ASTM standards cover C95400 castings?

ASTM B148 for sand castings, ASTM B271 for centrifugal castings, ASTM B505 for continuous castings, ASTM B806 for permanent mould (gravity die) castings and ASTM B763 for copper alloy sand castings used in valve applications.

Does C95400 resist seawater corrosion?

C95400 offers good resistance to seawater, brine and mine water and is used for splash‑zone and intermittently wetted marine hardware. For permanently immersed seawater service, or where selective phase (de‑aluminification) attack is a design concern, the nickel aluminium bronze grades C95500 and C95800 are the correct specification.

How hard is C95400 aluminium bronze?

As‑cast C95400 is typically 170 HB (150 HB minimum to ASTM B148). After TQ50 quench and temper heat treatment it typically reaches 195 HB, with a 190 HB minimum, making it suitable for heavily loaded wear surfaces running against hardened steel.

What is the minimum order quantity, and can you work to our drawing?

Our standard minimum order is 50 Kg per part number, with smaller trial quantities considered. We manufacture entirely to customer drawing, 3D model, sample or sketch, including pattern and core box manufacture in‑house, and can reverse engineer obsolete components.

Do you supply material test certificates?

Yes. EN 10204 3.1 certificates covering chemical analysis, mechanical properties and hardness are issued as standard with every shipment. Third‑party 3.2 certification and class society witnessing can be arranged on request.

Which countries do you export C95400 castings to?

We regularly export C95400 and AB1 aluminium bronze castings to the United Kingdom, United States, Canada, Germany, the Netherlands, France, Italy, Spain, Australia, New Zealand, the UAE, Saudi Arabia, Singapore, South Africa and Brazil.
