0.5" inch beryllium copper round bar C17200 Hard Drawn
Product Description
Alloy 25 is a high performance copper beryllium alloy used in
applications requiring strength, fatigue resistance, non magnetic
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.
