Red Brass C83600 Sand Castings

Alloy C83600 (ASTM B5854-836), the most common red brass, is called 85 metal or 85-5-5-5. It contains 85% copper and 5% each of tin, lead, and zinc. Typical uses for red brass are for low-pressure valves, pump housings, impellers, and fittings.

Alloy C89833 is a lead-free solution option for C83600 Red Brass that contains virtually no Selenium but does utilize Bismuth as a lead substitute. Typical uses are for potable water systems, pumps, impellers, and corrosion-resistant applications.
