Example Embodiment
[0028] The present invention will be described in detail below with reference to the embodiments.
[0029] First, prepare manganese Mn, iron Fe, silicon Si master alloys to ensure that the weight ratio of Mn to Si is close to 3:1, and the manganese-copper alloy contains 25% manganese Mn; the iron-copper alloy contains Fe 10%; and the silicon-copper alloy contains 20% Si.
[0030] The preparation method of brass alloy tube is as follows: according to 60-65wt% copper, 0.5-3.5wt% manganese, 0.5-3.5wt% silicon, 0.2-3.0 wt% lead, 0.05-0.2 wt% iron, 0.1-0.3 wt% nickel, 0.1-0.3 wt% aluminum, the balance is zinc and unavoidable impurities, the total amount of unavoidable impurities is not more than 0.1wt% of the composition ratio, electrolytic copper, manganese copper alloy, silicon copper alloy, iron copper alloy, lead ingot , Nickel, copper, and zinc ingots are smelted in the induction electric furnace in turn, the smelting temperature is 1030~1080℃, after the metal is all melted, the te...
