CuMg UHC

Lamifil’s CuMg UHC alloy delivers 10 to 16% higher conductivity compared to the EN50149 standard, while maintaining the required tensile strengths. Our (ASTM compliant) UHC contact wires with 85% conductivity have already been successfully implemented in Canada and Asia.

  • Reduced material costs
    Up to 6.5% savings in copper weight are possible, while maintaining high conductivity.
  • Lower costs
    Allowing longer substation intervals or reducing voltage drops, CuMg UHC significantly reduces overall costs.
  • Increased rail capacity
    Using the UHC alloy, operators can increase train frequency by up to 15%.
