Product Description
Beryllium copper, tin bronze, aluminum bronze, tungsten copper — high-purity alloys free from impurities. Non-standard specifications can be customized, and C17500 cutting services are available. The C17500 beryllium copper alloy belongs to the Cu-Be-Ni series and, thanks to its unique chemical composition and precipitation hardening properties, is widely used in fields requiring high strength combined with high conductivity.
The chemical composition of C17500 copper alloy is mainly composed of copper (Cu), beryllium (Be), and nickel (Ni). The presence of beryllium allows the C17500 alloy to undergo precipitation hardening after appropriate heat treatment, significantly improving its hardness and strength.
Precipitation hardening is a process that enhances the strength of metal materials through controlled heating and cooling. C17500 copper alloy achieves precipitation hardening through the following steps:
- Solution treatment: Heating the C17500 alloy to 780 °C–820 °C to fully dissolve beryllium in the copper matrix, followed by rapid quenching (usually water quenching) to maintain a uniform distribution of solute atoms in the solid solution.
- Aging treatment: Heating the solution-treated alloy to 310 °C–330 °C and holding it for several hours allows beryllium atoms to precipitate from the solid solution and form fine strengthening phases. These precipitated phases are usually γ (CuBe) or δ (NiBe) phases, which hinder dislocation movement and thereby improve the strength and hardness of the alloy.
The precipitation hardening treatment of C17500 alloy delivers excellent performance, especially a good balance between high strength and high conductivity.

Due to its excellent mechanical and physical properties, C17500 alloy is widely used in the following fields:
- Electronics industry: Commonly used to manufacture high-performance contactors, switches, connectors, and spring plates. Its high conductivity and strength ensure the reliability and durability of these electronic components.
- Aerospace: Used to manufacture components requiring high strength and light weight, such as springs and structural elements.
- Mold manufacturing: Its excellent wear resistance and thermal conductivity make it suitable for plastic molds and die-casting molds, improving mold service life and molding quality.
The C19900 series alloy adds titanium and other trace elements such as iron, lanthanum, and yttrium to copper to enhance performance. Compared with ordinary precipitation-hardened copper alloys, it improves the strength and hardness of the material, enhances product formability, and offers high strength, high hardness, high elongation, excellent formability, and good stress relaxation at high temperatures. It is widely used in electronic equipment and domestic military products, and is also suitable for certain mold materials.
