ABSTRACT:
A thermally conductive, wear-resistant alloy is particularly suited to cladding aluminum engine head valve seats. In the preferred embodiments, the alloys are metallurgically compatible with the cast Al—Si alloy used for the engine head. Three alternative embodiments are disclosed, namely, copper-based alloys; aluminum silicon-based alloys; and two-layer systems.
