MAIN CHARACTERISTICS 

An alloy with excellent cold forming, good hot forming properties and is well suited for e.g. coinage, beating, embossing. This alloy has a higher strength than pure copper. CuZn15 has good welding and brazing properties. It is principally used in jewellery, metal goods, watch industry and in electronic industry for installation parts.

CuZn15 has in general a good resistance to natural-, sea- and industrial atmosphere, water, water vapour, different saline solutions, many organic liquids, neutral- and alkaline bonds. CuSn15 has a low sensitivity to stress corrosion cracking. CuSn15 is not sensitive to dezincification, that could occur in water with high clorine content and low carbonat-hardness. Not particularly resistant to Oxidizing acids, hydrous sulphur components, hydrous ammonia in the non-stress-relieved condition.
