[0033]

[0034] Table 2

[0035]

[0036] The copper alloy material of the present invention is composed of the above-mentioned alloys. Compared with the original copper alloy for injection molds, the thermal conductivity is increased by 1.5 to 1.8 times, and the machinability is also significantly improved, especially when cutting at high speed, compared with the original injection mold Compared with copper alloy, it has increased by more than 10 times.

[0037] The alloy composition in the following Table 3 is obtained by smelting ingots, forging decomposition and hot working, 900°C solid solution treatment, rapid cooling in water, and aging treatment at 450-500°C. The hardness reaches HRC23.

Abstract

The invention relates to a copper alloy, which comprises nickel with a weight ratio of no less than 0.1 percent and smaller than 12.0 percent, cobalt with a weight ratio of no less than 0.1 percent and smaller than 12.0 percent as well as copper and impurity remaining, wherein, the total weight ratio of the nickel and cobalt is 2.0 to 12.1 percent. The invention can be used as the processing mold in formation of plastic material, and electrode material for machine welding. The copper alloy mold material has the advantages of increasing the thermal conductivity greatly, shortening the cycle of molding injection and improving the machinability distinctively, compared with the former copper alloy of injection molding mold. The copper alloy used in welding machine has the advantages of high strength, good conductivity, high precision of parts process and high feasibility of production, compared with the former beryllium copper material.

Description

technical field [0001] The invention relates to a copper alloy and its application. Background technique [0002] Originally, most of the mold materials used for plastic materials such as injection molding are carbon steel and tool steel. Due to the low thermal conductivity of these materials, the injection cycle time during injection molding will become longer. In order to solve this problem, various proposals have been made regarding the use of copper alloys as mold materials for injection molding, such as: CDA Ally No C-1800 Japanese Special Publication No. 62-14215, Japanese Patent Publication No. 2-190430, and Patent Publication 4- Publication No. 218631 proposes the use of Cu-Ni-Si alloys. These materials have higher thermal conductivity than conventional steel materials. Although they meet the above requirements, they are not enough for machinability. [0003] Therefore, it is desired to have a molding die material with high thermal conductivity and excellent machin...
