Copper Manganese alloys

CuMnNi & CuMnSn products

CuMn product

Highly controlled resistivity. _Very low temperature dependence on resistivity.

Our Copper Manganese alloys are widely recognised for their quality and reliability. They are used in a large range of stringent applications, notably due to their dielectric properties.

  • Possibility to achieve very tight restance on final component
  • High stability of resistance over large range of temperature
  • Ability to miniaturize components by choosing low resistivity grades
