CuZn36 is the major brass alloy for the cold forming process. Even though brasses with lower Zinc content have better cold forming properties, CuZn36 is the most used alloy. Reasons for this are on the one hand economical due to lower price of Zinc compared to Copper, on the other hand the forming properties of this alloy meet the demand of many applications . The alloy type is listed in the USA by EPA to have good antimicrobial properties..

CuZn33, as well as CuZn28 and CuZn30 is combining excellent cold forming properties with good mechanical strength. CuZn30 has good hot forming properties and excellent soldering and brazing properties. Due to the outstanding deep drawing properties CuZn33 and the other two mentioned alloys are called “deep-draw” or “cartridge” brass. We produce qualities with grain sizes below 5 μm if needed. The alloy type is listed in the USA by EPA to have good antimicrobial properties.

CuZn15 has 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 as well as a good corrosion resistance and is not fragile to stress corrosion and dezincification. It is principally used in jewellery, metal goods, watch industry and in electronic industry for installation parts. We produce qualities with grain sizes below 5 μm if needed. The alloy type is listed in the USA by EPA to have good antimicrobial properties.

CuZn10 has very good cold forming properties and is well suited for e.g. coinage, beating, embossing. This alloy has a higher strength as pure copper. It has good welding and brazing properties as well as a good corrosion resistant and is not fragile to stress corrosion and dezincification. CuZn10 is principally used in jewellery, metal goods, watch industry and in electronic industry for installation parts.We produce qualities with grain sizes below 5 μm if needed.
