Beryllium copper sheet properties.

Beryllium copper physical properties brush 60 c17460 yield strength. Applications are in springs connectors switches and automotive parts. Beryllium copper 20c uns c82500. C17200 is also known as alloy 25 and is the most commonly utilized beryllium copper alloy and is notable for exhibiting the highest strength and hardness compared to commercial copper alloys.

Like pure copper it is resistant to non oxidizing acidslike hydrochloric acid and carbonic acid to plastic decomposition products to abrasivewear and to galling. Properties edit beryllium copper is a ductile weldable and machinable alloy. Oftentimes shortened to becu beryllium copper is an extremely versatile alloy that s desirable for many different applications and industries. Here are five of the properties it s known for.

It can be heat treatedfor increased strength durability and electrical conductivity. The high conductivity alloys nickel beryllide in copper have a range from 0 15 to 0 7 weight percent beryllium. Mechanical properties measured at room temperature 68 f 20 c temper sectioncold size typ work. Its strength and hardness is similar to that of steel.

This alloy is ideal for investment sand or ceramic casting and provides excellent replication of intricate detail. 0 05 offset el rockwellvickens hardness. 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. You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures.

Beryllium copper alloys combine form ability with very high strength properties when aged. 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.
