Copper Base Alloys

Copper Base Alloys

Brass Strip (70%). This is the standard brass strip most generally used consisting essentially of 70% copper and 30% zinc and classified by the Copper Development Association, Inc., formerly the Copper and Brass Research Association as "Copper Alloy No. 260 (Cartridge Brass, 70%)." Yellow in color, Alloy 260 is harder and stronger than either of its alloying elements, copper and zinc. It is highly corrosion resistant, has excellent electrical properties, is malleable, ductile and capable of developing high tensile strength and hardness. Its strip tempers range from dead soft to extra strong temper. It is not heat-treatable for hardening purposes.

Phosphor Bronze Strip - 5% A. This is a standard commercial grade extensively used by industry in all tempers but principally in the harder cold rolled tempers. It consists essentially of copper, alloyed with tin (copper 95% - tin 5%) which has been deoxidized with phosphorus. Classified by the Copper and Brass Research Association, now the Copper Development Association, as "Copper Alloy No. 510 (Phosphor Bronze, 5% A)." It has excellent resistance to corrosion and fatigue, wear and chemicals. It possesses good electrical conductivity, excellent toughness, fine grain structure and develops high tensile strength. It is not heat-treatable for hardening purposes.

Copper and Nickel Silver - Full range of alloys and sizes available on special order.

Note - Sizes and tempers available vary over time. Please inquire if your needs are not shown.

The minimum order for PSW coil products is $400.
