Beryllium copper contacts sheet mod.

Copper beryllium alloy is commonly used to make bushings bearings and springs. 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. 4977 is known for allowing excellent detail in your casting combined with high strength and an attractive color. 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.

Beryllium is also found as a trace metal in slags and fly ash. Beryllium copper is non sparking but physically tough and nonmagnetic fulfilling the requirements of atex directive for. Beryllium alloys are classified into two types. Beryllium copper is a copper alloy that is composed of 0 5 to 3 beryllium and other elements.

The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel. Mead metals carries alloy 172 beryllium copper in annealed quarter hard and half hard tempers from 0 003 to 0 060. The commercial grades of beryllium copper contain 0 4 to 2 0 percent beryllium. 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. High beryllium content up to 30 beryllium and low beryllium content 2 3 beryllium. It displays exceptional machining forming and metalworking capabilities along with a combination of high strength non magnetic and non sparking qualities. 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. Unfortunately beryllium dust is highly toxic so manufacturing methods that create airborne particulates cannot process it. Beryllium copper battery contacts are one of the more popular items manufactured here at atlantic precision spring. Full hard and mill hardened tempers are stocked on a limited basis.

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.
