Beryllium Copper Sheet Properties

Special heat treating of the wire at the mill produces a mill hardened hm tempered beryllium copper wire which can then be formed and used without additional heat treatment.

Beryllium copper sheet properties.

Applications are in springs connectors switches and automotive parts. Diamond pyramid rockwell b or c rockwell superficial electrical conductivity iacs. 0 05 offset el rockwellvickens hardness. Beryllium copper physical properties brush 60 c17460 yield strength.

Oftentimes shortened to becu beryllium copper is an extremely versatile alloy that s desirable for many different applications and industries. Beryllium copper 20c uns c82500. This alloy offers high strength hardness wear resistance with excellent fluidity. It can be heat treatedfor increased strength durability and electrical conductivity.

Beryllium copper 20c uns c82500. Beryllium copper alloys combine form ability with very high strength properties when aged. This alloy is ideal for investment sand or ceramic casting and provides excellent replication of intricate detail. Like pure copper it is resistant to non oxidizing acidslike hydrochloric acid and carbonic acid to plastic decomposition products to abrasivewear and to galling.

The maximum mechanical properties are obtained by treatment at 310 330 c for a period of 2 to 3 hours at temperature depending on the initial temper of the metal. Properties edit beryllium copper is a ductile weldable and machinable alloy. Mechanical properties measured at room temperature 68 f 20 c temper sectioncold size typ work. You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures.

Min temp tensile strength yield strength 0 5 ext. The high conductivity alloys nickel beryllide in copper have a range from 0 15 to 0 7 weight percent beryllium.
