Working with C92610-M07
Is C92610 easy to machine?
Free-machining thanks to the lead phase — use sharp positive-rake carbide or HSS tools, high speed, light feed and flood coolant; chips break short.
Can C92610 be welded?
Poor fusion weldability (lead causes hot cracking and porosity); repair by brazing or by low-heat gas/TIG with matching Cu-Sn filler and preheat, or use soft solder.
Can C92610 be formed, bent or molded?
Casting alloy only — wide freezing range needs good gating, risers and chills to avoid interdendritic shrinkage; suited to sand, permanent-mould, centrifugal and continuous casting.
What surface finishes work on C92610?
Takes tin, nickel or chrome plating well after careful degreasing; chemical patina or lacquer for decorative parts; polishing limited by lead smearing.

What is the yield strength of C92610-M07?
C92610-M07 has a typical yield strength of 165 MPa (23.9 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 64% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is C92610-M07 easy to machine?
Yes — machinability is rated very good (80/100, better than 86% of copper alloy grades). Free-machining thanks to the lead phase — use sharp positive-rake carbide or HSS tools, high speed, light feed and flood coolant; chips break short.
Can C92610-M07 be welded?
Not readily — weldability is rated poor (25/100). Poor fusion weldability (lead causes hot cracking and porosity); repair by brazing or by low-heat gas/TIG with matching Cu-Sn filler and preheat, or use soft solder.
What surface finishes work on C92610-M07?
Takes tin, nickel or chrome plating well after careful degreasing; chemical patina or lacquer for decorative parts; polishing limited by lead smearing.
Can C92610-M07 be formed, bent or molded?
Casting alloy only — wide freezing range needs good gating, risers and chills to avoid interdendritic shrinkage; suited to sand, permanent-mould, centrifugal and continuous casting.
What is the maximum service temperature of C92610-M07?
C92610-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 C92610-M01 and C92610-M07?
M01 is the default condition — standard as-cast condition for bearings, bushings, pump and valve components produced in sand moulds. M07: best choice for stock bar/tube to be machined into bushings — dense, porosity-free structure with the highest strength and hardness of the cast conditions. Yield strength is 145 MPa in M01 versus 165 MPa in M07.
