example 1
[0021] Zinc-aluminum alloy, wherein the atomic percentage of metal aluminum in the alloy is 55%. First, 663g of zinc ingots containing 99.99% of zinc and 337g of aluminum ingots containing 99.7% of aluminum are placed in a vacuum induction melting furnace to melt into ZnAl 55 For alloy ingots, the melting temperature is 650°C, the dummy speed is 50-80mm / min, the cutting size is Φ18-30mm, and the lubricant is high-quality carbon ink. Then put the finished alloy ingot into a rotary forging machine for rotary forging to make its composition uniform. The heating temperature of the rotary forging is 400°C, the forging temperature is 400°C, and the final forged size is Φ8-15mm. Then put the forged alloy wire into the drawing equipment for medium-temperature drawing. At this time, the heating temperature is 350°C, the drawing temperature is 300°C, and the finally drawn alloy wire has a specification of Φ2.5-4mm.
