Beryllium Copper Strip
Beryllium, when alloyed with copper, produces metal strip that can justifiably be described as the heat treatable, high strength, copper alloys. Heat-treated, this alloy metal strip has an electrical conductivity between 20-60 % IACS and possible tensile strengths of 500-1300 N/mm2.
High Strength (high beryllium) Metal Strip
Higher beryllium content alloys (1.6-2.1%) combine high strength with the lowest conductivity and higher cost. The high strength and proof stress makes these beryllium copper strip alloys ideally suited for conducting springs and contacts.
High Conductivity (low beryllium) Metal Strip
Lower beryllium content metal strip alloys (less than 0.7%) offer a metal strip with greater electrical conductivity and cost benefits at the expense of strength.
