Description

A kind of high-strength aluminum alloy

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 field such as industry, civilian, building, and current industrial aluminum has many different wanting Ask, such as high intensity, high tenacity and good decay resistance etc..The quantity that at present high-strength aluminum alloy uses at industrial circle with Scope gets more and more, but alloy aluminum of the prior art exists many problems, it is impossible to meet machine-shaping, surface quality and Re Chu The aspects such as reason, this makes to be restricted high-strength aluminum alloy material use in industrial circle.

Summary of the invention

It is an object of the invention to provide a kind of aluminium alloy technical scheme, aluminum alloy materials can ensured by the program There is while high-intensity performance good processing characteristics.

The present invention is achieved by the following technical solutions:

A kind of high-strength aluminum alloy, includes following material count by weight percentage and forms: the silicon of 0.2-0.3%, The ferrum of 0.5-0.8%, the copper of 1.2-1.5%, the manganese of 0.03-0.05%, the magnesium of 0.5-0.8%, the vanadium of 0.3-0.5%, 0.05- The zirconium of 0.1%, the chromium of 0.05-0.2%, the zinc of 6.0-7.0%, the tungsten of 0.1-0.3%, the scandium of 0.001-0.003%, 0.001- The boron of 0.005%, the titanium of 0.03-0.05%, surplus is aluminum and a small amount of unavoidable impurity.

Described high-strength aluminum alloy, in its composition, the relation of copper and two kinds of elements of zinc is the content range at two elements In, the middle point range of copper is 1.35%, and the midpoint of zinc is 6.5%, the zinc when the compositing range of copper is between 1.2-1.35% Scope is between 6.5-7.0%；When the composition of copper is between 1.35-1.5%, the scope of zinc is between 6.0-6.5%；Do not deposit In the scope of zinc when the scope of copper is 1.35% 6.5%.

The invention has the beneficial effects as follows:

By technical scheme, optimize the formula of existing high-strength aluminum alloy material, improve and be processed into Type ability, also improves surface quality and the surface treatment properties of converted products, has high intensity simultaneously.

Detailed description of the invention

Technical scheme is described in detail below in conjunction with specific embodiment.

Aluminum alloy materials in the inventive solutions is mainly produced by hot-working, and particularly hot extrusion processing is raw Produce.

The techniques such as production and processing in the present invention compared with aluminum alloy production process and device the most identical, change is only It is the change to aluminum alloy materials composition, therefore says the most one by one in the present invention and following each embodiment Bright.

Unit selected in the present invention is weight percentage, respectively forms in the case of not illustrating Unit be weight percentage.

Described high-strength aluminum alloy, in its composition, the relation of copper and two kinds of elements of zinc is the content range at two elements In, the middle point range of copper is 1.35%, and the midpoint of zinc is 6.5%, the zinc when the compositing range of copper is between 1.2-1.35% Scope is between 6.5-7.0%；When the composition of copper is between 1.35-1.5%, the scope of zinc is between 6.0-6.5%；Do not deposit In the scope of zinc when the scope of copper is 1.35% 6.5%.The midpoint of wherein said copper refers to (1.2%+1.5%)/2= 1.35%；The midpoint of described zinc refers to (6.0%+7.0%)/2=6.5%.
