Embodiment
[0030] The alloy compositions of the samples of Examples 1-5 and Comparative Group 1 and Comparative Group 2 are shown in Table 1, and rods of Φ22 mm were manufactured.
[0031] The production process of the alloys listed in Table 1 is the same, try to ensure comparability. The production process is as follows:
[0032] (1) each component is batched according to proportioning;
[0033] (2) Heating to 1000-1050°C for smelting, using a horizontal continuous casting process to produce ingots;
[0034] (3) The ingot is heated up to 550°C, and then extruded in a 1350-ton extruder at an extrusion speed of 10mm / s, and the extruded billet is cooled and interrupted;
[0035] (4) The interrupted extruded billet is peeled to remove surface defects, then stretched, straightened, and subjected to stress relief annealing to obtain a finished brass alloy.
[0036] The surface of the brass alloy is passivated, and the passivation method comprises the following steps:
[0037] (a) Degreasi...
