Melt
Copper cathode and graded scrap melt in an induction furnace. No combustion gas touches the metal, which keeps oxygen and impurities in check.
Most traders stop at the warehouse. Hyperion Industries melts, casts and rolls copper into the rod that cable makers draw into wire. Scroll to follow the metal down the line.

1,050 °C
The melt runs down a launder into the groove of a turning casting wheel and leaves it as a continuous bar.
900 to 600 °C
Stands of rolls, set alternately flat and upright, squeeze the hot bar down in steps until it is rod.
40 °C
A quench tube cools and cleans the rod, and a laying head lays it in rings into a coil of three to five tonnes.
Typical values for 8 mm Cu-ETP rod. Every coil ships with a mill certificate giving the measured figures for its heat.
| Material | Cu-ETP (electrolytic tough pitch copper), CW004A |
|---|---|
| Standards | EN 1977, ASTM B49 |
| Copper content | Cu + Ag ≥ 99.95% |
| Conductivity | ≥ 100% IACS (≥ 58.0 MS/m at 20 °C) |
| Oxygen | 150 to 400 ppm |
| Elongation | ≥ 35% (200 mm gauge) |
| Tensile strength | about 220 MPa |
| Diameter tolerance | 8.0 mm ± 0.4 mm |
| Surface | Bright, oxide-free; continuous length, no joins |
8 mm is the standard for wire drawing. Larger diameters are made to order for busbar, profiles and earthing. Pick a size to see it at actual size and what a five-tonne coil holds.
The group’s manufacturing company. It runs the copper rod line, holds the mill certificates and handles technical questions from cable plants.
