Abstract

The invention discloses a high-strength aluminium alloy. The high-strength aluminium alloy comprises the following components in percentage by weight: 0.4-0.8% of Si, less than or equal to 0.7% of Fe, 0.15-0.4% of Cu, less than or equal to 0.15% of Mn, 0.8-1.2% of Mg, 0.04-0.14% of Cr, less than or equal to 0.25% of Zn, less than or equal to 0.15% of Ti, 0.2-0.4% of Pb, 0.4-0.8% of Bi and the balance of Al and inevitable impurities. The surface of an insert manufactured by using the high-strength aluminium alloy disclosed by the invention has few cold shut and cracks, the tensile strength of the insert reaches 290Mpa-360Mpa, the Rp of the insert reaches 240-330Mpa, the percentage elongation after fracture of the insert is 4%, and the Brinell hardness of the insert reaches 85-100HBW.

Description

technical field [0001] The invention relates to an aluminum alloy, in particular to a high-strength aluminum alloy. Background technique [0002] Aluminum is the second largest metal material after steel in output. Due to its good performance, wide application, large demand and low recycling cost, it is known as the "universal metal". Statistics show that 113 of the 124 industries in my country use aluminum products, and the industry correlation is as high as 91%. Therefore, the aluminum industry is one of the important pillar raw material industries for the sustainable development of the national economy. [0003] Aluminum alloy is an extended product of pure aluminum. The density of pure aluminum is small (ρ=2.7g / m3), about 1 / 3 of that of iron, and its melting point is low, about 660°C. Aluminum has a face-centered cubic structure, so It has high plasticity (δ: 32-40%, ψ: 70-90%), so it is easy to process, can be made into various profiles and plates, and has good corrosi...
