Anucha Metals is a leading supplier of Beryllium Copper C17200 Bars and Rods, known for their exceptional strength, hardness, and wear resistance. Known as Alloy 25, C17200 is one of the strongest copper-based alloys and is used in heavy-duty electrical and mechanical applications. Manufactured in Bangkok, our bars meet ASTM B196, B197, and AMS 4535 standards. Offered in various tempers, C17200 is suitable for applications that need non-magnetic, corrosion-resistant materials with high fatigue strength.
C17200 contains 1.8–2.0% beryllium and the rest copper. It delivers tensile strength up to 1380 MPa and hardness between 38–44 HRC after aging. Electrical conductivity ranges from 22–30% IACS. This alloy provides high fatigue strength, resistance to stress relaxation, and excellent dimensional stability under cyclic loading.
