Brass Equal Tee / Brass Compression Fitting for Pex-Al-Pex Pipe (EM-F-A118)

Because of lead brass with excellent hot and cold processing properties and machinability, combined with good mechanical and physical performance, price, cheap, and is widely used in instruments and meters, electronics, electrical appliances, daily hardware, system for drinking water, etc, among them with dosage biggest Hpb59-1. Water system components, however, lead in electronics, electrical appliances, and other waste to enter the water or soil, when after intake will produce harm to human body. So the United States, Japan, the European Union and countries are restricted and puts forward the corresponding provisions, namely to July 1, 2006, electrical and electronic products exported to the countries and regions and plumbing, hardware equipment shall meet the requirements of lead. Therefore, the research of the free-cutting nonleaded brass are thriving, but its processing technology was studied. In this paper, we adopt two phase (alpha + beta) using bismuth brass instead of traditional lead in free-cutting brass. Control of zinc equivalent coefficient in 40 ~ 43%. Adjust the Bi content to different ways of hot working, verify the validity of the design parameters. Successfully produce excellent bismuth brass material, make it quickly replaced the use of leaded brass material
