Beryllium Copper Sheet Properties

The high conductivity alloys nickel beryllide in copper have a range from 0 15 to 0 7 weight percent beryllium.

Beryllium copper sheet properties.

Beryllium copper physical properties brush 60 c17460 yield strength. Applications are in springs connectors switches and automotive parts. Properties edit beryllium copper is a ductile weldable and machinable alloy. Its strength and hardness is similar to that of steel.

Beryllium copper alloys combine form ability with very high strength properties when aged. C17200 copper s ultimate tensile and rockwell hardness properties in a peak aged condition are in the 200 ksi range and rc 45 respectively electrical conductivity 22 iacs minimum. 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. Min temp tensile strength yield strength 0 5 ext.

Like pure copper it is resistant to non oxidizing acidslike hydrochloric acid and carbonic acid to plastic decomposition products to abrasivewear and to galling. Mechanical properties measured at room temperature 68 f 20 c temper sectioncold size typ work. This alloy offers high strength hardness wear resistance with excellent fluidity. 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.

Here are five of the properties it s known for. 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 is ideal for investment sand or ceramic casting and provides excellent replication of intricate detail. 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. It can be heat treatedfor increased strength durability and electrical conductivity.

You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures. Beryllium copper 20c uns c82500.
