Beryllium Copper Contacts Sheet Mod

Beryllium copper or becu is often used in metal spring clips and flat springs because of its elastic properties formability non metallic nature and its electrical conductivity.

Beryllium copper contacts sheet mod.

20c beryllium copper belmont product code. 17410 17460 and 17510 are also obtainable. Beryllium copper combines high strength with non magnetic and non sparking. Beryllium copper alloy 20c cda 825 is our most popular offering in this category and contains 2 beryllium 0 5 cobalt and 0 25 silicon.

The first of the two families c17200 and c17300 includes high strength with moderate conductivity while the second family c17500 and c17510. Copper beryllium alloy is commonly used to make bushings bearings and springs. The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel. 4977 is known for allowing excellent detail in your casting combined with high strength and an attractive color.

Beryllium copper battery contacts are one of the more popular items manufactured here at atlantic precision spring. Beryllium copper is a copper alloy that is composed of 0 5 to 3 beryllium and other elements. Unfortunately beryllium dust is highly toxic so manufacturing methods that create airborne particulates cannot process it. Commonly stocked beryllium copper.

Most material that is purchased for beryllium copper contacts is uns c17200 which is certified to 97 9 copper cu 1 9 beryllium be 02 cobalt co. The full physical properties are density 302 lb cu in elastic modulus 10 6 psi 19 thermal expansion coefficient 70 0 f to 400 0 f 9 7 x 10 6 thermal conductivity btu ft hr 0. It displays exceptional machining forming and metalworking capabilities along with a combination of high strength non magnetic and non sparking qualities. Beryllium copper is a material commonly specified for electrical contacts because it is electrically conductive and can be made very springy by heat treating after it has been bent to shape.

Beryllium copper is a non ferrous alloy used in springs spring wire load cells and other parts that must retain their shape under repeated stress and strain it has high electrical conductivity and is used in low current contacts for batteries and electrical connectors. Beryllium copper is non sparking but physically tough and nonmagnetic fulfilling the requirements of atex directive for. The commercial grades of beryllium copper contain 0 4 to 2 0 percent beryllium. Beryllium is also found as a trace metal in slags and fly ash.

Beryllium alloys are classified into two types.
