NBC ONE Valve Guides
Non-Beryllium Copper Valve Guides
PVD Valve stem coatings are tough. Used with inferior valve guide materials they will literally “take out” the guides. Our NBC ONE material is the answer. The same toughness and thermal conductivity that make it great for seats also works for guides.
What Makes our NBC ONE Valve Guides Better?
Beryllium-Free copper alloy enhanced with nickel and silicone for wear toughness.
Excellent thermal conductivity.
Highly compatible with PVD and DLC seat coatings.
Nickel and silicone enhanced for toughness against our MICRO-PVD coating. As the engine is initially run, a nikasil type matrix forms on the seat surface. The nickel silicon matrix is very hard, but it is comparatively ductile. The copper composition of the guide acts as a cushion to deter valve bounce.
