Description
C17200 Beryllium Copper Electrode Rod — High-Strength Alloy for Precision Welding & EDM Applications
C17200 Beryllium Copper Electrode Rod is also known as Alloy 25. It contains 1.8-2.0% beryllium and is the toughest and strongest of any copper based alloy after age hardening. The rod is manufactured by Dongguan Jiaye Dingsheng Precision Casting & Forging Co., Ltd. Founded in 1997, the firm has more than 25 years of expertise in processing copper alloys. The rod is made via vacuum melting, precision rolling and controlled heat treatment. Tensile strength is 1100-1300 MPa, hardness is 36-42 HRC and electrical conductivity is 22-25% IACS. A good material for resistance welding, EDM tooling and precision mould components.
What’s Special About C17200 Beryllium Copper Compared to Standard Copper?
The standard electrolytic copper is not hard enough for high pressure welding or abrasive mould applications. Tool steels, in contrast, are poor conductors of heat and electricity.
Grade C17200 Beryllium Copper Electrode Rod fills that niche. It gets to 45 HRC after age hardening at 315°C (600°F) for 2–3 hours, with 22–25% IACS conductivity, which no conventional copper or steel can equal.
This makes it especially ideal for situations where the electrode tips are exposed to regular mechanical stress, heat cycling or chemical exposure.
