Copper Extrusions

As a Specialty Copper Mill our high quality extruded shapes, rods and bars are produced from billets we cast in-house. The necessary materials are carefully combined in our two large induction furnaces and prior to pouring each heat the chemical composition is  evaluated in our laborato ry. This ensures precise control of the desired alloy composition. The billets are then cast in a controlled environment and cut to predetermined lengths for the extrusion process. Once the billets are thoroughly heated they are extruded in one of our two hydraulic presses.

Semi finished copper extrusions are then transferred to our drawing area where they are pointed and drawn. Within our mill department we have many pieces of specialized equipment to point, draw, straighten, co ld roll and  coil material. 

At specific points in the manufacturing process, we check and monitor the chemical, mechanical & electrical properties of the material to guarantee that it meets or exceeds your specification. 

Some of the tests we routinely perform include:

  • Tensile
  • Emission Spectrometer
  • Rockwell Hardness
  • Conductivity
  • Resistivity
  • Hydrogen Embrittlement
  • Oxygen PPM Analysis
  • Atomic Absorption Spectrometer Testing
  • Grain Size Evaluation.

As a leading producer of custom and standard shaped copper extrusions we carry an extensive tooling inventory consisting of several thousand dies. However, if custom tooling is necessary you can rely on our seasoned toolmakers and state of the art equipment to produce all required extrusion and draw dies in house.

We can provide a material Certificate of Compliance with your shipment or if requested, we will conduct Full Metal Tests for a minimal charge. We welcome the opportunity to review your copper extrusion requirements. Please submit your questions or quotation requests to TEMCO.SalesWebsite@elecmat.com
