Alloy 25 beryllium copper alloyAlloy 25 (C17200)

High Strength Copper Beryllium Alloy

Alloy 25 is a high performance copper beryllium alloy used in applications requiring strength, fatigue resistance, nonmagnetic properties, conductivity, and corrosion resistance. Alloy 25, supplied with certified mechanical properties, is fully heat treated and no additional treatment is required.Alloy 25 magnetic properties are unaffected by machining and surface abrasion.

Galling &Wear Resistance:

Alloy 25 provides excellent galling resistance to itself and other alloys at high load conditions. Galling resistance, high hardness and low friction provide wear resistance in bearing and bushing applications under conditions of marginal lubrication.

Corrosion Resistance:

AAlloy 25’s corrosion resistance is similar to pure copper. It resists corrosion in sea water, most organic solutions, non-oxidizing acids, and dilute alkalis. Alloy 25 is not subject to hydrogen embrittlement, and it resists stress corrosion cracking in sulphide and chloride solutions. It meets the requirements of NACE MRO175. Alloy 25 is not recommended for use with ammonium hydroxide or strongly oxidizing acids.
