COPPER EXTRUSION MANUFACTURING
SPECIALTY COPPER EXTRUSION PROCESS
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 before pouring each heat, the chemical composition is evaluated in our laboratory. 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, cold roll, and coil material.
At specific points in the manufacturing process, we check and monitor the chemical, mechanical, and 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
