Yellow Brass C85700 Sand Castings
Alloy C85700 (ASTM B5854-857) has 65% Copper with 1% Lead, 1% Tin and 35% Zinc. It has excellent casting and machining characteristics. The machinability rating is 80 (Fee cutting brass = 100). It is suitable for being joined by soldering (good) and brazing (good) but is not recommend for Oxyacetylene Welding or Arc Welding.
Typical applications for sand casting alloy C85700 are hardware fittings, architectural components where aesthetics are important, decorative and ornamental castings.
