Example Embodiment

[0016] Embodiment 1, a copper rod, in terms of mass percentage, it includes the following components: silicon 0.15-0.35%, copper 60-61%, iron 0.05-0.2%, aluminum 0.15-0.4%, tin <0.1%, nickel <0.05%, lead<0.15%, zinc 37~39%; total content of other impurities ≤0.5%.

Example Embodiment

[0017] Embodiment 2, a manufacturing process of a copper rod: including the following steps:

[0018] Step (1): Sort the raw materials into storage according to different varieties, and make obvious signs; when selecting materials, they must be treated in strict accordance with the principle of maximizing copper materials, and the materials that do not meet the process requirements and hazardous materials are separately disposed of ; In the selection of materials, iron wires, non-metals and other sundries must be selected and stacked separately, and the strong magnetic inspection is used to pick out the bright iron; after the raw materials pass the inspection, they are based on silicon 0.15%, copper 60%, iron 0.05%, and aluminum 0.15 %, tin <0.1%, nickel <0.05%, lead <0.15%, zinc 37%; the proportion of other impurities ≤0.5% is weighed and then sent to a temperature of 1050℃ for smelting into copper water;

Abstract

The invention discloses a copper bar and a manufacturing method thereof. The copper bar comprises the following components in mass by percentage: 0.15-0.35% of silicon, 60-61% of copper, 0.05-0.2% of ferrum, 0.15-0.4% of aluminum, less than 0.1% of tin, less than 0.05% of nickel, less than 0.15% of lead, 37-39% of zinc, and less than or equal to 0.5% of total content of other impurities. According to the invention, the problems that the existing production technological process of the copper bar is complicated, the rate of produced finished products is relatively low, the lead content is high, the product performance is unstable, and mass demand of the market cannot be met can be solved.

Description

technical field [0001] The invention relates to a copper rod and a manufacturing method thereof. Background technique [0002] Because of its excellent conductivity, plasticity and ability to withstand cold and hot processing, copper is widely used in electrical, sanitary, valve industries and other fields. With the further development of electrical, sanitary, and valve industrial technologies, the requirements for copper materials are increasing. The higher, the existing copper rod production process is complicated, the production yield is relatively low, the lead content is high, the product performance is unstable, and it cannot meet the mass demand of the market. Contents of the invention [0003] The purpose of the present invention is to provide a copper rod and its production method, which can solve the problems of complex production process of existing copper rods, relatively low production yield, high lead content, unstable product performance, and inability to me...
