After heat treatment beryllium copper can be as strong/hard as high grade steels . However is retains coppers much greater heat conductivity, the thermal expansion is closer to that of aluminum and has a decent amount of corrosion resistance this makes it very good valve seat material.

Beryllium copper. Beryllium copper is an alloy comprising of copper as the base and 0.5 to 3 % of beryllium. In some cases, other alloying elements like nickel or cobalt are also used. The alloy has a huge demand in innumerable industries due to its high strength in adjunct with non-magnetic and non-sparking properties.
beryllium copper closely matches that of steels including the stainless grades. This insures that beryllium copper and steel are compatible in the same assembly. Specific heat of beryllium copper rises with temperature. For Alloys 25, M25 and 165, it is 0.086 Btu/(lb•F) at room temperature, and 0.097 Btu/(lb•F) at 200 F. For Alloys 3, 10
Cool Blue. Cool Blue is an abrasive spec created by Goodson specifically for grinding the Copper Beryllium valve seats found in high-performance applications. Copper Beryllium is a copper alloy with 0.5% – 3% Beryllium and sometimes with other alloying elements. Copper Beryllium combines high strength with non-magnetic and …
Some Be-Cu valve seats are 97% copper with 1.8 to 2.0% beryllium, and have a hardness of 38 to 41 Rockwell C. Other alloys …
Beryllium copper seats are often used in drag racing, NASCAR, Formula 1 and Indy racing because the material works well with titanium valves and has a higher …
Speaking of titanium valves, another choice of seat would be Beryllium copper. This material is noted for high strength and thermal conductivity. The greatest asset would be the ability to remove heat from the valve while taking a beating. Beryllium is only used in extreme racing applications. This is due primarily to the expense: a seat can ...
Beryllium copper, an alloy of copper and beryllium, is prized for its exceptional strength, hardness, electrical conductivity, and thermal conductivity. Widely used in applications requiring precision and reliability, such as electronic connectors, springs, and tools, its non-sparking and non-magnetic properties also make it valuable in ...

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 …
The most common recommendation from valve seat suppliers for cast seats being installed in aluminum heads is .003˝ to .005˝ of interference fit. If you are installing powder metal seats, use .005˝ to .007˝ of interference. If you are using beryllium-copper seats, go with .004˝ to .0045˝ of interference fit.
Pro-1 Racing Valve Seats. These valve seats are made out of an innovative non-beryllium copper material. Unlike most other copper seats available, our seats lack the hazardous beryllium element, making them non-toxic to machinists. Our seat material also dissipates heat seven-times as quickly as the stock powdered steel seat material.
These work especially well in Nitrous Oxide and Turbo applications. CHE also offers Ductile Iron and Beryllium Copper valve seats. All of our seats offer ultra tight tolerances with …
C17000 beryllium copper is a high-strength alloy with excellent conductivity and is resistant to wear, fatigue, and corrosion.

Alro stocks C17200, also known as Alloy 25, the most commonly utilized beryllium copper (BeCu) alloy. It is notable for exhibiting the higher strength and hardness compared to commercial copper alloys. 172 Beryllium Copper's strength and hardness is similar to that of steel. Beryllium Copper has extremely high hardness and tensile strength but ...
Nickel-silicon-chromium copper alloy seats provide an excellent alternative to the beryllium copper seats commonly used in racing today. The high thermal conductivity and wear resistance offer improved seat …
The BeCu doesn't "pull" the heat out, it speeds transfer because it has high thermal conductivity. If the head is hotter than the spring, the heat will transfer quicker from the head to the spring. If the head is cooler than the spring, the heat will transfer quicker from the spring to the head. You need to know your running temps of your parts ...
The copper beryllium seat is machined with a 50-degree seat and 40-degree top angle. Just below the seat is a very narrow 60-degree cut that Ertman says helps a 50-degree flow like a 55-degree. …
Copper seats, however, do offer a significant improvement in intake valve life. Probably, I think, mostly from the reduced operating temp of the valves (titanium's strength at high temps falls off more rapidly than steel valve alloys). Copper alloys include beryllium/copper (beryllium is toxic). Various proprietary alloys such as "Moldmax ...
In the fully heat treated and cold worked condition, beryllium copper (BeCu) is the hardest (HV 100-420) and strongest (tensile strength 410-1400 N/mm2 ) of any copper alloy. Beryllium copper is similar in mechanical properties to many high strength alloy steels but, compared to steels, it has better corrosion resistance, higher electrical ...

Beryllium copper seats would also require more maintenance in a street engine than ductile iron seats," says Haumont. It appears that ductile irons seats were used in the early days of titanium valves, so I assume they will work, but may not have the cooling properties needed for these valves. This is NOT an all out racing motor, just a …
