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.

Here are five of the properties it s known for. Min temp tensile strength yield strength 0 5 ext. It can be heat treatedfor increased strength durability and electrical conductivity. Its strength and hardness is similar to that of steel.

Applications are in springs connectors switches and automotive parts. 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. Beryllium copper physical properties brush 60 c17460 yield strength. Temper heat treatment tensile strength ksi 0 2 offset ksi elongation fatigue strength.

Under load yield strengthstrength 0 2 offset yield. 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. You ll notice beryllium copper used in cryogenic equipment because it keeps its strength even at low temperatures. Beryllium copper 20c uns c82500.

This alloy offers high strength hardness wear resistance with excellent fluidity. 3 4 ht th03 mill hardened 115 135 95 115 11min 46 47 50min ht th04. Beryllium copper alloys combine form ability with very high strength properties when aged. Oftentimes shortened to becu beryllium copper is an extremely versatile alloy that s desirable for many different applications and industries.

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. Mechanical properties measured at room temperature 68 f 20 c temper sectioncold size typ work. Beryllium copper 20c uns c82500. Like pure copper it is resistant to non oxidizing acidslike hydrochloric acid and carbonic acid to plastic decomposition products to abrasivewear and to galling.
