Plastic Injection Pre Hardened ElmedurB2 - V Steels Skip to main content

Plastic Injection

– Pre Hardened –

ElmedurB2

Precipitation hardened alloy with good thermal conductivity and high hardness.

Chemical Composition

CODE DIN Be Ni+Co Cu
CuBe2 CW101C 2.1247 2,0 0,4 balance

Material Properties

  • Precipitation hardened alloy with good thermal conductivity and high hardness.
  • Not suitable for case hardening or nitriding.

Applications

  • Plastic blow and injection moulds
  • Inserts in steel tools on spots requiring higher cooling rates. Due to a high tensile strength also suitable for inserts with a high ratio of length/cross section
  • Nozzles and needles for hot runner systems
  • Cooling inserts in moulds and ingot moulds

Heat Treatment

HEAT TREATMENT TEMPERATURE TIME COOLING HARDNESS HV
Solution annealing 750-800°C 1/2 h Water max. 210
Precipitation hardening 325°C min 2 h Water or air c. 400
