Alloy 3 Beryllium Copper

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 needed. 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 seawater, 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.

Typical Applications

Commercial applications for this engineering material include:

Automotive welding
Marine applications
Chemical processing equipment
Thermal management
Metal & plastic moulding

We stock Alloy 3 in a variety of shapes.
