Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the examples.

[0021] The following preparation method was adopted in the examples, and the chemical composition and properties of the examples are shown in Table 1.

[0022] a. Dosing, feeding, smelting and casting according to mass percentage: the feeding sequence is: first add electrolytic copper and industrial pure nickel, add copper-chromium master alloy after melting, and then add copper-beryllium master alloy; use medium frequency induction furnace for melting, The melting temperature is 1300-1350°C, and the casting temperature is 1200-1250°C; during the melting process, the surface of the liquid is covered with charcoal to prevent oxidation, and the thickness is 20mm.

[0023] b. Car wash.

[0024] c. Thermal deformation processing (hot forging or hot rolling): the thermal deformation processing temperature is 900-1000°C, and the temperature is kept for 2 hours.

[0025] d. Solution t...

Abstract

The invention discloses a high-conductivity, high-strength, and high-hardness copper alloy. The chemical element composition and mass percentage contained in the copper alloy are: Be 0.1-0.2%; Ni 0.6-1.6%; Cr 0.5-1.2%; the balance It is Cu; other trace elements and impurities are less than 0.5%. Its preparation method is composed of alloy composition design: melting and casting, processing and deformation, and heat treatment. The alloy of the present invention adopts a small amount of multiple elements to form binary and ternary compounds that can be solid-soluble in copper. After aging treatment, its strength can reach 935Mpa, hardness HRB105, electrical conductivity 67.4%, and softening temperature 650°C. It is a high-strength, Materials with high hardness, high electrical conductivity, and good comprehensive physical and mechanical properties. It is used in high-strength, high-hardness, high-conductivity, high-heat-resistant components, such as welding machine nozzles, spot welding heads, electrodes, generator slot wedges, electrical industry frames, etc., and has broad application prospects.
