Free Cutting Brass

Featuring good machinability, for example, free cutting bronze such as JIS C3604 and ASTM C36000 are common work-piece for Lathe (numerical or CNC) in mass production. Not only is it eco-friendly, low content in cadmium, chromium, mercury but suitable for producing components of PC, electronic usage, Bathroom Accessories, watch & clock, fishing tackles, pens, illuminations, bolts, nuts, optical, medical, valves, camera and other hardware because of its excellence in machinability, cold-forging and ductility.
