Copper Alloy Strip, Coil, & Bar
When it comes to high conductivity applications in the electrical and electronics industry, few materials can offer the advantages of copper alloys. IRG has engineered the use of several high conductivity copper alloys in a range of electrical power system equipment applications. IRG can assist our customers in specifying the appropriate alloy for the application as well as the most cost effective size and form.
If you currently use copper alloy strip, coil, or bar for your electrical application, consider an alloy review to see whether a more cost effective option may exist for your application.
IRG supplies the following alloys:
