Description
C17200 Beryllium Copper Rod H04 – High-Strength Precision Bar Stock for Demanding Industrial Applications
C17200 Beryllium Copper Rod H04 is a precipitation-hardening copper alloy with 1.80–2.00% beryllium and trace cobalt and nickel. Manufactured by Dongguan Jiaye Dingsheng since 1997, the H04 temper rod adopts cold working and aging treatment, reaching 1110–1320 MPa tensile strength and 36–42 HRC hardness. It maintains 22–25% IACS conductivity and complies with ASTM B196, RWMA Class 4 and ISO 5182 standards. Available in 5–100mm diameters, all batches support full compliance certification and come with EN 10204 3.1 MTC test reports.
What Is C17200 Beryllium Copper Rod H04?
C17200 Beryllium Copper Rod H04 refers to hard-temper beryllium copper formed by cold working and 315°C constant-temperature aging treatment. This process refines internal grain structure and stabilizes overall dimensional performance. It balances the mechanical strength of alloy steel and the conductive and thermal transfer properties of copper materials, making up for the performance shortcomings of single standard steel and ordinary copper alloys for industrial use.
