Working with C95600-M07
Is C95600 easy to machine?
Machines noticeably better than iron-bearing aluminium bronzes — use rigid setups, positive-rake carbide, moderate speed with generous coolant to avoid work-hardening and built-up edge.
Can C95600 be welded?
GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well; remove the tenacious Al₂O₃ film, keep interpass temperature moderate and avoid high heat input to limit hot cracking.
Can C95600 be formed, bent or molded?
Foundry alloy: silicon gives good fluidity and reduced hot-tear sensitivity, but design for directional solidification with chills/risers and degas the melt; not intended for cold forming.
What surface finishes work on C95600?
Takes a bright mechanical polish and develops a protective brown patina; not anodizable — use passivation, lacquer, or electroless nickel/chrome plating for appearance or wear duty.
C95600 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.

C95600-M07 — frequently asked
What is C95600-M07 used for?
C95600-M07 is typically used for valve bodies, marine hardware and corrosion-resistant fittings. In short: easiest-machining aluminum bronze; silicon improves castability; good seawater corrosion resistance.
What is the yield strength of C95600-M07?
C95600-M07 has a typical yield strength of 214 MPa (31 ksi) and a tensile strength of 448 MPa (65 ksi) — weaker than 52% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is C95600-M07 easy to machine?
Reasonably — machinability is rated good (58/100, better than 73% of copper alloy grades). Machines noticeably better than iron-bearing aluminium bronzes — use rigid setups, positive-rake carbide, moderate speed with generous coolant to avoid work-hardening and built-up edge.
Can C95600-M07 be welded?
Yes — weldability is rated good (60/100). GTAW/GMAW with matching aluminium-bronze filler (ERCuAl-A2) works well; remove the tenacious Al₂O₃ film, keep interpass temperature moderate and avoid high heat input to limit hot cracking.
What surface finishes work on C95600-M07?

Can C95600-M07 be formed, bent or molded?
Foundry alloy: silicon gives good fluidity and reduced hot-tear sensitivity, but design for directional solidification with chills/risers and degas the melt; not intended for cold forming.
What is the maximum service temperature of C95600-M07?
C95600-M07 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 C95600-M01 and C95600-TQ50?
M01 is the default condition — standard commercial condition for pump housings, valve bodies and marine fittings poured in sand moulds. TQ50: rarely supplied for this alloy; specify only when a foundry offers a heat-treated variant for higher strength and hardness. Yield strength is 193 MPa in M01 versus 240 MPa in TQ50.
