Chinese patent CN200810243568.0 involves brass alloy smelting technology, especially a high-strength wear-resistant brass smelting technology. The preparation method of the invention has the following steps: a. Preliminary preparation: baking the metal surface; b. Metal smelting: in Add manganese, cobalt and iron in sequence to the corundum crucible, add copper, zinc and aluminum to the melt after melting, smelt and take samples for analysis and get out of the furnace to obtain high-strength wear-resistant brass. Cobalt is added to the brass, and the mass content of copper is 58~ 65%, the mass content of iron is 2-8%, the mass content of zinc is 20-26%, the mass content of manganese is 2-6%, the mass content of aluminum is 3-9%, and the mass content of cobalt is 0.03%. Some brass alloys cannot meet the requirements of bearing parts. The hardness can reach more than 235HB, the tensile strength is equal to 780MPa, the yield strength is greater than 680MPa, and the elongation is above 12%.
Although this technology uses common alloy elements, the cost is low, but the mechanical properties are relatively low.
