Working with C95200 M01-AsCast
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.
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 M01-AsCast — frequently asked
What is C95200 M01-AsCast used for?
C95200 M01-AsCast 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 M01-AsCast?
C95200 M01-AsCast 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 M01-AsCast 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 M01-AsCast 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.
What surface finishes work on C95200 M01-AsCast?
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.
Can C95200 M01-AsCast 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 M01-AsCast?
C95200 M01-AsCast 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.
