C84400 alloy

Technical characteristics

UNS C84400 is semi-red brass alloy that contains 7−10% of zinc, and not less than78% of copper. This is a modern substitute of tombak. Due to modern technological possibilities, there are can be manufactured the most complex details out of semi-red brass. These details can be joined by brazing with a help of braze solders. There is not recommended to use such types of welding: arc welding in atmosphere of protective gas, carbon electrode welding, oxy-acetylene welding.
