BERYLLIUM COPPER ALLOY :

Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze and spring copper, is a copper alloy with 0.5-3% beryllium and sometimes with other alloying elements. Beryllium copper combines high strength with non-magnetic and non-sparking qualities. It has excellent metalworking, forming and machining qualities. It has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace. Beryllium-containing alloys create an inhalation hazard during manufacturing due to their toxic properties.

PROPERTIES :

Beryllium copper is a ductile, weldable, and machinable alloy. It is resistant to non-oxidizing acids (for example, hydrochloric acid, or carbonic acid), to plastic decomposition products, to abrasive wear and to galling. Furthermore, it can be heat-treated to improve its strength, durability, and electrical conductivity. Beryllium copper attains the highest strength (to 1,400 MPa (200,000 psi)) of any copper-based alloy


ALLOYS:

Alloy 25 beryllium copper (C17200 & C17300) is an age-hardening alloy which attains the highest strength of any copper base alloy. It may be age hardened after forming into springs, intricate forms or complex shapes. It has superb spring properties, corrosion resistance and stability as well as good conductivity and low creep.

Tempered beryllium copper is Alloy 25 (C17200 & C17300) that has been age hardened and cold drawn. No further heat treatment is necessary except for a possible light stress relief. It is sufficiently ductile to wind on its own diameter and can be formed into springs and most shapes. Tempered wire is most useful where the properties of beryllium copper are desired, but age hardening of finished parts is not practical.

Alloys 3 (C17510) and 10 (C17500) beryllium copper are age-hardenable and provide excellent electrical conductivity in combination with good physical properties and endurance strength. Provided in either the age-hardenable condition or as tempered ware, they are used in springs and wire forms which are electrical conductors, or where retention of properties at elevated temperatures is important.
