ABSTRACT:
A composite material component for an injection molding assembly includes a first portion formed of a precipitation hardened, high thermal conductivity material and a second portion formed of a precipitation hardened, high strength material, which are integrally joined together. The thermal conductivity of the high thermal conductivity material is greater than the thermal conductivity of the high strength material, and at least one strength aspect of the high strength material has a value greater than the corresponding value of the same strength aspect of the high thermal conductivity material. The high thermal conductivity material and the high strength material can be precipitation hardened together under the same precipitation hardening conditions to achieve increases in the value of at least one strength aspect of the high thermal conductivity material and the value of at least one strength aspect of the high strength material, relative to their respective unhardened conditions.
