What is C83600 Leaded Red Brass?
C83600 leaded red brass is a cast copper alloy commonly used for valves, fittings, pump parts, plumbing components, and general cast hardware. It is often called SAE 40, ounce metal, or 85-5-5-5 because the alloy is built around copper with roughly balanced additions of lead, tin, and zinc.
For bearing and bushing buyers, C83600 is not the same choice as C93200 / SAE 660. It is useful for cast components that need good machinability, pressure-tightness, and corrosion resistance, but the final selection should follow the drawing, pressure service, and applicable lead-content requirements.

RFQ Details for C83600 Parts
Send the alloy callout, casting or machined-part drawing, pressure or fluid service if applicable, finished dimensions, tolerances, quantity, certification requirements, and any lead-content restrictions. If the part is a bearing under moderate load, compare C83600 with C93200 / SAE 660 bearing bronze.
