Product Description
Product Overview
0.2mm x 20mm CW101C Beryllium Copper Alloy C17200 wire, engineered for high-performance temperature controller springs and relay applications requiring exceptional strength and thermal properties.
Material Specifications
Beryllium Copper C17200 Alloy
C17200 (CDA 172) Beryllium Copper delivers the highest strength and hardness among commercial copper alloys, with ultimate tensile strength exceeding 200 ksi and hardness approaching Rockwell C45. This alloy maintains excellent electrical conductivity (minimum 22% IACS) and exceptional resistance to stress relaxation at elevated temperatures.
