New High Performance Beryllium Free Alloy
Winsert’s newly developed composite copper alloy valve seat inserts possess both excellent wear resistance and high thermal conductivity, which are two key material properties required by high performance racing engines. High temperature laboratory valve and insert test results show that composite copper alloys are much better wear resistant alloys than copper beryllium alloys as well as nickel bronze type copper alloys currently used in the high performance engines.
High performance engine laboratory tests also confirm the excellent wear resistance of the composite copper alloy valve seat inserts. Special oxide film formed on the copper alloy provides good compatibility with DLC coated titanium valves or plain titanium valves. The greatly improved composite copper alloys gives engine valve train designers more freedom to enhance engine performance because they are wear resistance alloys.
The new copper alloy is also environmentally friendly, with no hazard beryllium, and achieves superior wear resistance. The unique combination of excellent high temperature sliding wear resistance and high thermal conductivity, together with good compatibility of mating components, makes the new composite copper alloy suitable for many other demanding applications, including valve seat inserts.
