Dura-Bond's 70000 Series valve seats use a sintered, high speed (tungsten carbide) tool steel, valve seat insert. This material has special additives blended into the matrix which impart high temperature lubrication properties to the valve seat. These lubrication properties are “built-in” throughout, and are not affected by extreme heat or machining. These solid lubricants enable this material to be used in “dry” fuel applications such as propane (LPG) and natural gas. They prevent the “micro-welding” of the valve seat material to the valve face, therefore eliminating the primary cause of valve seat erosion. They also improve the machinability: Your tools last longer and you can cut faster.

Because of the special high temperature sintering and post heat treat processing, this valve seat material has cermet style metal alloy oxides - this gives it superior wear resistance to pounding abrasive ware at elevated temperatures. These metal alloy oxides are called “cer-met” style because they are similar to ceramic (they do not soften at elevated temperature), but retain the machinability of metal. It is this high tech, new generation processing that allows Dura-Bond to achieve such high, hot hardness without having to put in massive amounts of expensive alloys, which would be required to achieve equal performance.
