VALVE GUIDES
We choose to use the copper based C63000 nickel-aluminum
bronze as a material to make our bronze valve guides because of its ideal
characteristics for the application. The 5% nickel content provides superior resistance to wear, and the
approximately 80 percent copper content delivers outstanding heat conductivity. KPMI® guide profiles
are designed to have minimal effect on the airstream while maintaining critical cross sectional thick-
ness in high temperature areas, which promotes high performance and endurance.
