Copper Bar
Copper Bar is just one of the wide range of copper products available from Goodfellow. With 7 different variations, our copper bar can be customized to take advantage of its thermal and electrical conductivity, strength and malleability. This makes it perfect for a wide range of applications, including electrical wiring, heat sinks, fuel injectors, suspension systems and rocket engines. As a ductile and corrosion-resistant metal, copper is ideal for far-reaching uses ranging from electrical systems to industrial equipment. With Goodfellow's Copper Bar selection, engineers and designers can find the right product to meet their needs.
