What is C95200?
C95200 is a basic aluminium bronze casting alloy with about 9 % aluminium and iron, the entry grade of the copper-aluminium cast bronzes. It is chosen for general industrial hardware needing strength plus corrosion resistance, cast by sand, centrifugal and continuous routes, with 552 MPa tensile strength, 207 MPa yield, 30 % elongation and 115 HB. Machinability is only about 50 % of free-cutting brass and the tenacious alumina film complicates casting and plating; for seawater duty and higher strength, C95800 nickel-aluminium bronze is the usual step up. C95200 has a density of 7.64 g/cm³ (0.276 lb/in³), lighter than 92% of copper alloy grades. It melts at 1,043°C (1,909 °F). C95200 has a yield strength of 207 MPa (30 ksi) and a tensile strength of 552 MPa (80.1 ksi) — weaker than 52% of copper alloy grades. Elongation at break is 30% and the elastic modulus is 110 GPa (16 Msi).

Working with C95200
Is C95200 easy to machine?
Machines like a tough gummy bronze at ~50 % of free-cutting brass: use sharp positive-rake carbide, rigid setups, moderate speeds with generous coolant to avoid work-hardened skin and built-up edge.
Can C95200 be welded?
GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well; keep interpass temperature low, clean the tenacious Al₂O₃ film mechanically before each pass, and avoid oxyacetylene.
Can C95200 be formed, bent or molded?
A casting alloy only — sand, centrifugal and continuous cast; needs quiescent bottom filling, generous chills/risers and oxide-skim control because the oxide film causes lap defects.
C95200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| Alprimary strengthener, forms α+κ structure | 8.5 – 9.5 | 9 |
| Fegrain refiner / κ-phase former | 2.5 – 4 | 3 |
| Mnresidual limit (per B505 named-element practice) | ≤ 0.5 | |
| Niresidual limit; Ni-bearing service grades are C95500/C95800 | ≤ 1 | |

| Cu86 % min per ASTM B148/B505 | ≥ 86 (balance) |
What surface finishes work on C95200?
Not anodizable; pickle/passivate or shot-blast then paint, or leave bare for seawater service. Polishes to a golden lustre but tarnishes; electroless nickel or chrome plating requires activation of the aluminium oxide.

C95200 — frequently asked
What is C95200 used for?
C95200 is typically used for valve bodies, gears, bushings and marine hardware. In short: entry-level aluminium bronze; weldable cast bronze; high elongation, 30 %.
What is the yield strength of C95200?
C95200 has a typical yield strength of 207 MPa (30 ksi) and a tensile strength of 552 MPa (80.1 ksi) — weaker than 52% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is C95200 easy to machine?
Reasonably — machinability is rated fair (45/100, better than 64% of copper alloy grades). Machines like a tough gummy bronze at ~50 % of free-cutting brass: use sharp positive-rake carbide, rigid setups, moderate speeds with generous coolant to avoid work-hardened skin and built-up edge.
Can C95200 be welded?
Yes — weldability is rated very good (70/100). GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well; keep interpass temperature low, clean the tenacious Al₂O₃ film mechanically before each pass, and avoid oxyacetylene.

Can C95200 be formed, bent or molded?
A casting alloy only — sand, centrifugal and continuous cast; needs quiescent bottom filling, generous chills/risers and oxide-skim control because the oxide film causes lap defects.
What is the maximum service temperature of C95200?
C95200 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C95200 M01-AsCast and C95200-TQ50?
M01-AsCast is the default condition — standard stocked condition for pump/valve bodies and general hardware; best ductility, lowest cost. TQ50: choose when higher yield strength and hardness are needed for gears, wear plates and heavily loaded bushings. Yield strength is 207 MPa in M01-AsCast versus 276 MPa in TQ50.
