Beryllium Copper Sheet Properties

Like pure copper it is resistant to non oxidizing acidslike hydrochloric acid and carbonic acid to plastic decomposition products to abrasivewear and to galling.

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. It can be heat treatedfor increased strength durability and electrical conductivity. Temper heat treatment tensile strength ksi 0 2 offset ksi elongation fatigue strength.

Oftentimes shortened to becu beryllium copper is an extremely versatile alloy that s desirable for many different applications and industries. Its strength and hardness is similar to that of steel. Under load yield strengthstrength 0 2 offset yield. You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures.

This alloy is ideal for investment sand or ceramic casting and provides excellent replication of intricate detail. 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. Applications are in springs connectors switches and automotive parts.

Properties edit beryllium copper is a ductile weldable and machinable alloy. 3 4 ht th03 mill hardened 115 135 95 115 11min 46 47 50min ht th04. 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. The high conductivity alloys nickel beryllide in copper have a range from 0 15 to 0 7 weight percent beryllium.

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. Beryllium copper 20c uns c82500.
