Beryllium copper combines high strength with non-magnetic and non-sparking ...

The thermal conductivity is 15% greater than that of beryllium copper, thus greatly reducing the temperature of the exhaust valve. This remarkable formula was also designed to minimize valve "bounce," associated with high RPM (above 8000) and with radical cam grinds lacking a sufficient closing ramp. ... The expansion rates of this seat are ...

Mar 24, 2016· Copper provides good thermal conductivity to pull heat out of the valve when the valve is closed. For many years, copper-beryllium alloy seats were used with titanium valves. Copper-beryllium alloys typically contain less than 3% beryllium. Even so, beryllium dust is dangerous and requires special precautions when machining seats.

(because Beryllium Copper is toxic to humans) This comes with a financial cost, but it well worth it. We get the benefits of the copper seats but not the safety concerns. Simply, More Powerful- Because these seats machine so much easier than steel seats they achieving a good sealing valve job with little effort. It is said that as much as 75% ...

Beryllium Copper valve seats. Performance Head Engineering can install Beryllium Copper valve seats. These valve seats have excellent thermal qualities with enough hardness to keep the valve seat from pounding out. This helps extend the life of titanium valves and transfers heat more efficiently than stock valve seats.

One of the highest strength copper based alloys available on the market today is beryllium copper, also known as spring copper or beryllium bronze. The commercial grades of beryllium copper contain 0.4 to 2.0 percent beryllium. The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel.

The most popular alloy in the copper beryllium family is UNS C17200 and is commonly known as beryllium copper Alloy 25. In Europe, this alloy is referred to as CuBe2. It has 1.8 – 2% Beryllium and is the hardest and strongest copper beryllium material widely used.

mend seat materials such as beryllium copper. Beryllium copper seats are often used in drag racing, NASCAR, Formula 1 and Indy rac-ing because the material works well with titanium valves and has ahigher thermal conductivity than steel alloy seats. The main reason why racers use beryllium copper is for cooling the valves. For racing ...
