beryllium copper is C17200 and C17300, which have been age-hardened and cold-drawn. No further heat treatment is necessary beyond possible light stress relief. It is sufficiently ductile to wind on its diameter and can be formed into springs and most shapes. The tempered wire is most useful where the

as C17200 to C17400, the cast alloys are C82000 to C82800. The hardening process requires rapid cooling of the annealed metal, resulting in a solid-state solution of beryllium in copper, which is then kept at 200-460 °C for at least an hour, producing a precipitation of metastable

Beryllium copper valve seats and guides are used in high-performance four-stroke engines with coated titanium valves. BeCu dissipates heat from the valve as much as seven times faster than powdered steel or iron seats and guides. The softer BeCu reduces valve wear and increases valve

C17510 and C17500 beryllium copper alloys are age-hardenable and provide good electrical conductivity, physical properties, and wear-resistance. They are used in springs and wire where electrical conduction or retention of properties at elevated temperatures is important.

Copper alloys in general have always been considered non-sparking. C17200 has the strength to withstand use in hand and mechanical tools. These non-sparking features are best applied in explosive environments such as in the oil & gas and gunpowder industries.

alloys contain as much as 0.7% beryllium with some nickel and cobalt. The thermal conductivity of these alloys is greater than that of aluminum and slightly less than that of pure copper; they are often used as electrical contacts.
245:. Compared to steel tools, beryllium copper tools are more expensive and not as strong, but the properties of beryllium copper in hazardous environments may outweigh the disadvantages. Some of BeCu's varied uses include:
