CDA, along with its brass and bronze ingot-producing member companies, has developed lead-free brass casting alloys. The alloys, called EnviroBrass I, II and III, employ a combination of selenium and bismuth to provide good castability and free-machining performance while offering significant environmental, health and safety benefits to foundrymen, machine shops, plumbing manufacturers and end users.
