The Electric Materials Company (TEMCO) has been providing quality copper forgings for over 90 years to a wide variety of industries including the electrical, transportation and mining markets. High quality forgings in high conductivity copper, chrome copper (conforming to RWMA Class II), and brass or bronze are available to meet your requirements. 

With over 400,000 square feet of manufacturing space available our expertise covers several key facets of copper production. In addition to our forging capabilities we offer extrusion production, sand & centrifugal castings, assembled fabrications, complete component machining, brazing & welding, commutator manufacturing, AC rotor manufacturing, heat treating and electroplating.   



Choosing the right material

With almost 50 different non-ferrous copper alloys available our engineering team will help you select the right material and process to produce a final product meeting all of your forging requirements. For a complete listing of available alloys click here.

Obtaining the right material  

As a vertically integrated specialty copper mill, TEMCO produces its own forging stock. Materials are produced in our own extrusion mill and foundry. Mechanical and chemical properties are certified by our in-house metallurgical lab. Outsourcing raw materials is eliminated minimizing lead-times.

Processing the material  

Often several operations or processes must be done to achieve desired material properties. All processes can be done in-house shortening your lead-time and delivering a completely finished product to you. We are your single source for quality forgings, complete metallurgical lab testing and certifications.


Equipment and Capabilities  

Our forge department is equipped with a full complement of 800 to 3500 pound drop hammers. Special presses are also available for close tolerance work, enhancing surface finish, flatness and mechanical properties. Forging, trimming and coining dies are produced in-house by our experienced toolmakers up to a maximum die block size of 24” x 24”. Our engineers will design the tooling best suited to your product and our in-house tooling production equipment will fabricate the forge dies. Whether your requirements call for 1 piece or several thousand pieces, our forge can process your order quickly and efficiently. Parts weighing as little as a few ounces or up to 100 pounds can be easily accommodated. 

Quality Systems and Compliance

Quality and dependable service are our primary concerns and all forgings are designed, engineered, manufactured and tested to the highest standards. All forgings are inspected regularly throughout the manufacturing process. A quality finished product begins with quality raw materials and at TEMCO this process begins with pre-pour chemistries since we produce our own billets and castings. Chemistries are evaluated to ensure proper alloy composition and compliance with customer specifications.
