Embodiment Construction

[0010] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0011] An aluminum alloy of the present invention, the weight percentage of each group is as follows, manganese: 0.1-0.5, nickel: 0.1-0.5, silicon: 2-2.5, iron: 1.5-2, copper: 0.5-2, zinc: 0.1-0.2 , chromium 1-2.5, the rest is aluminum and a small amount of unavoidable impurities, and the components are fully proportioned. The small amount of unavoidable impurities is not more than 0.1 parts by weight.

[0012] Add various raw materials according to the formula for smelting, fully stir and then carry out refining, slag removal and degassing. Put it into the casting machine to cast the strip, and then lead the cast strip into the rolling mill, the obtained aluminum alloy has a strength of 190MPa, an elongat...

Abstract

The invention provides an aluminium alloy. The aluminium alloy is composed of, by weight, 0.1 to 0.5 part of manganese, 0.1 to 0.5 part of nickel, 2 to 2.5 parts of silicon, 1.5 to 2 parts of iron, 0.5 to 2 parts of copper, 0.1 to 0.2 part of zinc, 1 to 2.5 parts of chromium, the balance aluminium, and a small amount of inevitable impurities. Casting performance of the aluminium alloy is excellent; electrical conductivity, thermal conductivity, strength, and toughness are improved; corrosion resistance, welding performance, and machinability are excellent; and the aluminium alloy is suitable to be used for preparing housing parts.

Description

technical field [0001] The invention relates to an aluminum alloy. Background technique [0002] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of industrial economy, the demand for welded structural parts of aluminum alloy is increasing day by day, so that the research on weldability of aluminum alloy is also in-depth. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel. . Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance. Hard alu...
