Abstract
The invention relates to a high-strength aluminum alloy material which comprises the components by weight percentage as follows: 0.2-0.3% of silicon, 0.5-0.8% of iron, 1.2-1.5% of copper, 0.3-0.5% of manganese, 0.5-0.8% of magnesium, 0.03-0.3% of chromium, 6.0-7.0% of zinc, 0.08-0.15% of titanium, and the balance of aluminum and avoidless impurities in a small amount.
Description
Technical field
The invention belongs to aluminum alloy materials, particularly relate to a kind of high-strength aluminum alloy material.
Background technology
Aluminum alloy materials is widely used in the fields such as industry, civilian, building, and present industrial aluminium has many different requirements, such as high strength, high tenacity and good corrosion resistance nature etc.Aldural is more and more in quantity and scope that industrial circle uses at present, but there are many problems in alloy aluminum of the prior art, can't satisfy the aspects such as machine-shaping, surface quality and thermal treatment, this is so that the use in industrial circle is restricted to high-strength aluminum alloy material.
Summary of the invention
The purpose of this invention is to provide a kind of aluminium alloy technical scheme, can in the high-intensity performance that guarantees aluminum alloy materials, have good processing characteristics by this scheme.
The present invention is achieved by the following technical solutions:
A kind of high-strength aluminum alloy material, including the following material of counting by weight percentage forms: the silicon of 0.2-0.3%, the iron of 0.5-0.8%, the copper of 1.2-1.5%, the manganese of 0.3-0.5%, the magnesium of 0.5-0.8%, the chromium of 0.03-0.3%, the zinc of 6.0-7.0%, the titanium of 0.08-0.15%, surplus is aluminium and a small amount of unavoidable impurity.
Described high-strength aluminum alloy material, the relation of copper and two kinds of elements of zinc was in the content range of two elements during it formed, the middle point range of copper is 1.35%, and the mid point of zinc is 6.5%, and the scope of zinc is between 6.5-7.0% when the compositing range of copper is between 1.2-1.35%; When the composition of copper was between 1.35-1.5%, the scope of zinc but did not comprise that scope when the scope of copper zinc 1.35% time is 6.5% between 6.0-6.5%.
The invention has the beneficial effects as follows:
By technical scheme of the present invention, optimized the prescription of existing high-strength aluminum alloy material, improved the machine-shaping ability, also improved surface quality and the surface treatment properties of converted products, have simultaneously high strength.
Embodiment
Describe technical scheme of the present invention in detail below in conjunction with specific embodiment.
Aluminum alloy materials in technical scheme of the present invention is mainly by hot-work production, particularly hot extrusion processing.
The techniques such as process for processing in the present invention are all identical with existing aluminum alloy production process and device, change only be change to the aluminum alloy materials composition, therefore in the present invention and following each embodiment, all illustrate no longer one by one.
