Alloy 3 beryllium copper alloyAlloy 3 (C17510)

High Conductivity Copper Beryllium Alloy

Alloy 3 is a high conductivity copper beryllium alloy used in applications requiring a combination of high thermal conductivity with moderate strength. Alloy 3, supplied with certified mechanical properties, is fully heat treated and no additional treatment is required. Alloy 3 is nonmagnetic and provides excellent resistance to thermal fatigue.

Corrosion Resistance:

Alloy 3’s corrosion resistance is similar to pure copper. It resists corrosion in sea water, most organic solutions, nonoxidizing acids, and dilute alkalis. Alloy 3 is not subject to hydrogen embrittlement, and it resists stress corrosion cracking in sulphide and chloride solutions. Alloy 3 is not recommended for use with ammonium hydroxide or strongly oxidizing acids.
