THERMOMET

ThermoMet (UNS C18000) is a copper nickel silicon chromium alloy with good strength and hardness along with high electrical and thermal conductivity.

To learn more about ThermoMet (C18000) physical and mechanical properties, forms and sizes, download our ThermoMet data sheet. For  information about tolerances, see the charts below.

ADVANTAGES AND BENEFITS

With its unique combination of thermal conductivity and strength, ThermoMet offers many benefits.

In plastic molds:

  • Shorter cycle time
  • Improved plastic part dimensional control
  • Better parting line maintenance
  • Excellent corrosion resistance

In resistance welding equipment:

  • Longer wear
  • Resists mushrooming

SPECIFICATIONS & STANDARDS

  • UNS Number C18000, RWMA Class III.
