Embodiment Construction
[0015] The present invention is described in further detail below in conjunction with accompanying drawing:
[0016] A bismuth brass drawn tube containing a trace amount of rare earth, its alloy composition is as follows: Cu: 58.0%-61.0%, Bi: 0.8%-1.5%, impurity elements: Pb≤0.03% , Fe≤0.15%, Sn≤0.15%, Al≤0.10%, Ni≤0.10%, Mn≤0.02%, Si≤0.02%, Cd≤0.003%, the balance is Zn; the amount of rare earth modifier: 0.05% ~0.15%, the rare earth modifier refers to a mixture of metals such as cerium and lanthanum.
[0017] Such as figure 1 As shown, the manufacturing method of the bismuth brass drawn tube containing a trace amount of rare earth comprises the following steps:
[0018] Ingredients: 2500kg / furnace according to the alloy ratio;
[0019] Melting: Put copper and part of zinc into the melting furnace in batches to melt and stir; after the above-mentioned copper and zinc are all melted, add the remaining zinc and bismuth; after all are melted, stir the alloy liquid for 5-10 min...
