Beryllium copper sheet properties.

Oftentimes shortened to becu beryllium copper is an extremely versatile alloy that s desirable for many different applications and industries. This alloy is ideal for investment sand or ceramic casting and provides excellent replication of intricate detail. Diamond pyramid rockwell b or c rockwell superficial electrical conductivity iacs. Beryllium copper physical properties brush 60 c17460 yield strength.

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. 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. Mechanical properties measured at room temperature 68 f 20 c temper sectioncold size typ work. Min temp tensile strength yield strength 0 5 ext.

Here are five of the properties it s known for. Applications are in springs connectors switches and automotive parts. Properties edit beryllium copper is a ductile weldable and machinable alloy. 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. Under load yield strengthstrength 0 2 offset yield. 0 05 offset el rockwellvickens hardness. Beryllium copper 20c uns c82500.

The high conductivity alloys nickel beryllide in copper have a range from 0 15 to 0 7 weight percent beryllium. You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures.
