Beryllium Copper Contacts Sheet Mod

Beryllium copper is non sparking but physically tough and nonmagnetic fulfilling the requirements of atex directive for.

Beryllium copper contacts sheet mod.

The small ratio of beryllium to copper creates a family of high copper alloys with strength as high as alloy steel. It displays exceptional machining forming and metalworking capabilities along with a combination of high strength non magnetic and non sparking qualities. Copper beryllium alloy is commonly used to make bushings bearings and springs. Beryllium is also found as a trace metal in slags and fly ash.

4977 is known for allowing excellent detail in your casting combined with high strength and an attractive color. 17410 17460 and 17510 are also obtainable. The commercial grades of beryllium copper contain 0 4 to 2 0 percent beryllium. High beryllium content up to 30 beryllium and low beryllium content 2 3 beryllium.

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 battery contacts are one of the more popular items manufactured here at atlantic precision spring. Mead metals carries alloy 172 beryllium copper in annealed quarter hard and half hard tempers from 0 003 to 0 060. Full hard and mill hardened tempers are stocked on a limited basis.

Unfortunately beryllium dust is highly toxic so manufacturing methods that create airborne particulates cannot process it. Beryllium alloys are classified into two types. 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. Commonly stocked beryllium copper.

The first of the two families c17200 and c17300 includes high strength with moderate conductivity while the second family c17500 and c17510.

Beryllium copper is a copper alloy that is composed of 0 5 to 3 beryllium and other elements.
