Example Embodiment
[0025] Example 1
[0026] An environmentally friendly lead-free new alloy material tube, which is composed of the following components: zinc accounting for 1% of the total weight of the alloy material tube, tin accounting for 1% of the total weight of the alloy material tube, and aluminum accounting for 0.5% of the total weight of the alloy material tube. The total weight of the alloy material tube is 0.05% antimony, 0.5% of the total weight of the alloy material tube is silicon, and the balance is copper.
[0027] Put the zinc, tin, aluminum, antimony, silicon, and electrolytic copper in the power frequency electric furnace according to the above ratio, heat it to 1250-1300 degrees Celsius, and then heat it to 1200 degrees Celsius; stir the completely melted alloy liquid with special graphite tools Afterwards, it is covered with high-purity flake graphite powder to prevent its oxidation, with a thickness of 11-13cm; after holding for 1.2-1.5 hours, use the German imported Spike di...
