Copper and Copper Alloy Specifications

Copper is a medium strength, non-magnetic metal. It has excellent electrical and thermal conductivity properties and has a comparatively low cost. In its purest form it is soft and malleable but the introduction of alloying elements provides many industrial and commercial uses.

Reynolds & Law’s extensive range of copper product types includes a variety of copper alloys which have a high level of corrosion resistance that makes them ideal for the production of everything from valves and pipe fittings to architectural extrusions. As a good conductor copper is the metal of choice for the manufacture of electrical busbars for the switchgear industry as well as wire for printed circuit boards.

Other uses include domestic cookware and various bio-medical applications.
