Working with C92200-M07
Is C92200 easy to machine?
Free-machining with the lead phase: use positive-rake carbide or HSS, high speed, light feed, soluble-oil coolant; chips are short and holes hold size well.
Can C92200 be welded?
Arc/gas welding is not recommended (lead causes hot cracking and porosity); repair by braze or soft solder, or use mechanical joints.
Can C92200 be formed, bent or molded?
A foundry alloy only — excellent fluidity and pressure tightness in sand, centrifugal and continuous casting; feed heavy sections to avoid tin sweat and interdendritic shrinkage.
What surface finishes work on C92200?
Not anodizable; take a bright turned or buffed finish, or apply tin, nickel or chrome plating; passivating/pickling in dilute sulphuric acid removes casting scale.

What is C92200-M07 used for?
C92200-M07 is typically used for valve bodies, pump housings, fittings and marine hardware. In short: standard valve-body bronze; pressure-tight and free-machining; lead blocks fusion welding.
What is the yield strength of C92200-M07?
C92200-M07 has a typical yield strength of 152 MPa (22 ksi) and a tensile strength of 276 MPa (40 ksi) — weaker than 67% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is C92200-M07 easy to machine?
Reasonably — machinability is rated fair (52/100, better than 69% of copper alloy grades). Free-machining with the lead phase: use positive-rake carbide or HSS, high speed, light feed, soluble-oil coolant; chips are short and holes hold size well.
Can C92200-M07 be welded?
Not readily — weldability is rated poor (25/100). Arc/gas welding is not recommended (lead causes hot cracking and porosity); repair by braze or soft solder, or use mechanical joints.
What surface finishes work on C92200-M07?
Not anodizable; take a bright turned or buffed finish, or apply tin, nickel or chrome plating; passivating/pickling in dilute sulphuric acid removes casting scale.
Can C92200-M07 be formed, bent or molded?
A foundry alloy only — excellent fluidity and pressure tightness in sand, centrifugal and continuous casting; feed heavy sections to avoid tin sweat and interdendritic shrinkage.
What is the maximum service temperature of C92200-M07?
C92200-M07 is rated for continuous use to about 260°C (500 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between C92200-M01 and C92200-M07?
M01 is the default condition — standard ASTM B61 sand-cast valve and fitting bodies; best all-round ductility and pressure tightness. M07: continuous-cast bar and tube (ASTM B505) for machined bushings and fittings — finer, more uniform structure and slightly higher yield than sand cast. Yield strength is 138 MPa in M01 versus 152 MPa in M07.
