Beryllium Copper |
Properties
In the fully heat treated and cold worked condition, beryllium copper (BeCu) is the hardest (HV 100-420) and strongest (tensile strength 410-1400 N/mm2 ) of any copper alloy. Beryllium copper is similar in mechanical properties to many high strength alloy steels but, compared to steels, it has better corrosion resistance, higher electrical conductivity (16-65%IACS) and higher thermal conductivity (210W/moC ). It is also non-sparking and non-magnetic. Applications Beryllium copper has long been used for non-sparking tools in the mining, gas and petrochemical industries. Because of the excellent fatigue resistance, beryllium copper is widely used for springs, pressure responsive diaphragms, flexible bellows, connectors, contacts and relays, which are all subject to cyclic loading. The anti-galling, strength and good corrosion resistance lead to the widespread use of beryllium copper for down hole drilling tools for the oil and gas industry. Miniaturisation Smaller component size has become a major design criterion in several industries. Companies are constantly looking for ways to reduce the size and weight of their products without sacrificing performance. The unique combination of strength, electrical and thermal conductivity of beryllium copper make it an ideal choice for miniaturised components in many applications. Forms The main product forms for beryllium copper are sheet, strip, wire, rod, tube and forgings. |
