WHAT IS C87500?
C87500 High Leaded Red Brass SAE 65 is a premium copper-based casting alloy designed for:
Excellent machinability
Superior casting fluidity
Good corrosion resistance
Pressure-tight industrial components
Marine and plumbing systems
Valve and pump bodies
The alloy belongs to the red brass family and is widely used where:
Complex casting geometry
Leak resistance
Smooth machining
Long-term durability
are critical.
Compared with ordinary brass alloys, C87500 provides better casting stability, dimensional consistency, and machining efficiency for industrial manufacturers.
Industry references show red brass alloys are widely used in pumps, valves, fittings, marine products, and industrial hardware due to their balanced corrosion resistance and machinability.
