Wrought Copper Alloys
Rods, Bars and Specialty Extrusions
The Electric Materials Company (TEMCO) specialty mills work with 26 wrought copper alloys regularly producing high quality rods, bars and extrusions. 
These products are available in an unlimited variety of shapes, sizes and lengths (copper alloy cold rolling, stamping, punching and other services are also available). As a fully integrated copper mill our process begins with copper billet production. Before each heat is poured our metallurgical laboratory analyzes the chemical composition for adherence to established standards. Material properties are checked again at regular intervals throughout the mill process per our in-house quality assurance program in coordination with our established ISO-9001:2008 quality control system.

Our vertical integration enables us to produce highly engineered components from billet production through the extrusion and cold working processes as well as finish machining and electroplating as required. In-house tool design and manufacture ensures rapid service and enables design changes to be implemented quickly. These unique capabilities keep all operations in-house and improves product throughput, minimizes scrap and reduces overall product costs.
