C84400 alloy specification and casting requirements
C84400 should not be described generically as interchangeable brass mill product. For a quotation, provide ASTM B584 or the governing project specification, casting method, component drawing, dimensions and tolerances, machining allowance, pressure or inspection requirements, certificate level, quantity and destination ZIP code.
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.
