Abstract

A high-hardness aluminum alloy with a new formula is obtained by adopting aluminum liquid regeneration smelting, and the generated aluminum alloy comprises the following components in percentage by weight: copper: 5-6%, magnesium: 3.2-3.4%, manganese: 0.3 to 0.7 percent of zinc, 8.0 to 9.0 percent of zinc, 0.2 to 0.3 percent of chromium, 0.05 to 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum. The obtained aluminum alloy has high hardness.

Description

High-hardness aluminum alloy with new formula
The technical field is as follows:
the invention relates to the field of aluminum alloy, in particular to a high-hardness aluminum alloy with a new formula.
Background art:
the aluminum alloy has low density, high strength similar to or superior to that of high-quality steel, good plasticity, excellent electric conductivity, heat conductivity and corrosion resistance, is widely used in industry, and is second to steel in use amount. Have found numerous applications in the aerospace, automotive, machinery, marine and chemical industries.
Cast aluminum alloys have been used in engines, crankshaft components since 1903, and through the last hundred years of development cast aluminum alloys have evolved into a large series of cast aluminum alloys. With the progress of society, demand for aluminum for aviation and aluminum for automobile weight reduction is increasing, particularly for high-hardness aluminum alloys.
The aluminum alloy manufactured by the method provided by the invention can greatly improve the hardness of the product.
The invention content is as follows:
the invention aims to provide a new formula high-hardness aluminum alloy which is high in hardness.
Another object of the present invention is to provide a high hardness aluminum alloy with a new formulation, which improves the hardness of the aluminum alloy.
The technical scheme adopted by the invention is as follows:
the aluminum alloy with high hardness is obtained by adopting aluminum liquid regeneration smelting, and the generated aluminum alloy comprises the following components in percentage by weight: copper: 5-6%, magnesium: 3.2-3.4%, manganese: 0.3 to 0.7 percent of zinc, 8.0 to 9.0 percent of zinc, 0.2 to 0.3 percent of chromium, 0.05 to 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
Further, according to the weight ratio: copper: 5%, magnesium: 3.4%, manganese: 0.7 percent of zinc, 9.0 percent of zinc, 0.3 percent of chromium, 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
Further, according to the weight ratio: copper: 5.5%, magnesium: 3.3%, manganese: 0.5 percent of zinc, 8.5 percent of zinc, 0.25 percent of chromium, 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
Further, according to the weight ratio: copper: 6%, magnesium: 3.2%, manganese: 0.3 percent, 8.0 percent of zinc, 0.2 percent of chromium, 0.05 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
The specific implementation mode is as follows:
example 1
A new formula of high-hardness aluminum alloy comprises the following components in parts by weight:
copper: 5%, magnesium: 3.4%, manganese: 0.7 percent of zinc, 9.0 percent of zinc, 0.3 percent of chromium, 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
Example 2
A new formula of high-hardness aluminum alloy comprises the following components in parts by weight:
copper: 5.5%, magnesium: 3.3%, manganese: 0.5 percent of zinc, 8.5 percent of zinc, 0.25 percent of chromium, 0.1 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
Example 3
A new formula of high-hardness aluminum alloy comprises the following components in parts by weight:
copper: 6%, magnesium: 3.2%, manganese: 0.3 percent, 8.0 percent of zinc, 0.2 percent of chromium, 0.05 percent of titanium, less than 0.2 percent of other impurities in total, and the balance of aluminum.
The embodiments described above are some, but not all embodiments of the invention.
