Embodiment Construction

[0008] This specific embodiment adopts the following technical scheme: its formula consists of: silicon 2.4%, copper 71%, iron 0.1%, manganese 0.05%, nickel 0.1%, lead 0.09%, tin 0.1%, zinc 26.16%.

[0009] The production process of this specific embodiment is as follows: 1. The purchased copper raw materials are inspected, weighed and put into storage after passing the inspection, and smelted at a temperature of 1030-1080 ° C. After smelting, the composition test is carried out. Component blending, followed by component testing. Products that pass the test are kept at a temperature of 1030-1035°C, and unqualified products are re-mixed until they pass the test; Pull the dead skin, and then temper the temperature to 320°C~325°C; 3. The tempered copper rods are inspected for finished products, and the qualified products are put into storage, and the unqualified ones are re-melted for production.

[0010] The tensile strength of the copper rod is 380~390N / mm 2 , The elongation a...
