Primary Metals and Alloys specializes in highly conductive, oxygen free, very pure copper for electrical and other manufacturing purposes (OF-OKTM). Our copper’s high purity provides you with electrical conductivity of at least 98% IACS which results in a typical oxygen content of 8ppm.
The most important property of our copper is its purity and freedom from oxygen. In addition, its great electrical and thermal conductivity, excellent weldability, brasability, solderability as well as good impact and fatigue strength guarantees you have a high quality end product time after time.

Service and quality are what we have built our company on and to guarantee a continuous supply of outstanding product, we only source our metal from ISO9001:2000 accredited mills.
Primary Metals and Alloys are able to supply you with the following copper solutions:
Primary Metals and Alloys has significant experience in sourcing the correct mill to ensure your requirements are met. We work with leading mills who lead the way in tooling design and in copper product development. This has resulted in their profile products being accurately matched to customer specifications and processes. Their tooling design is based on a thorough understanding of process and process control.
We see custom shapes as an opportunity for creative problem-solving and ingenuity, and believe that we have a genuine competitive strength in this area.
A sample, a drawing, or even a description of the desired shape gives our engineers enough of a starting point to develop the finished product. We regularly work CDA 10100, 10200, 10500, 10700, 11000, 12200, and 15000 alloys, but we welcome the opportunity to explore other possibilities for customised shape requirements.
