Make, boats and ships and chemical industry have obtained substantial amounts of application.Along with developing rapidly of industrial economy, for aluminum alloy welding access node
The snowball of component is increasing so that the welding performance for aluminium alloy requires more and more higher.Aluminium alloy density is low, light weight,
But intensity can be close to high-quality steel, and plasticity is good, it is possible to be processed into various section bar, there is excellent electric conductivity, heat conductivity and anti-corruption
Erosion performance.
Aluminium alloy can use heat treatment to obtain good mechanical performance, physical property and corrosion resistance.And aluminium alloy
It is grouped into according to its different one-tenth and is divided into duralumin, hard alumin ium alloy, extra super duralumin alloy and forging aluminium alloy；Wherein duralumin, hard alumin ium alloy belongs to AI Cu
Mg system, typically contains a small amount of Mn, heat-treatable strengthened. and it is characterized in that hardness is big, but plasticity is poor.Superduralumin belongs to Al mono-Cu
Mg Zn system, heat-treatable strengthened, it is the aluminium alloy that under room temperature, intensity is the highest. but corrosion-resistant, hot mastication is fast.Wrought aluminium closes
Gold mainly Al Zn Mg Si system alloy, although addition element kind is many, but content is few, thus has excellent thermoplastic
Property, suitably forge.
As fully visible, the performance of various aluminium alloy of the prior art is the most single so that thermoplasticity and corrosion resistance
The performances such as energy and heat treatment reinforcement are difficult to obtain preferably comprehensively, and existing aluminium alloy crackle is more, and elongation percentage is poor.
Based on this, researcher the raw material of aluminium alloy is made up of and studies, as number of patent application is
The aluminium alloy of 201510378121.4, composition is made up of the component of following weight percentage ratio: silicon 2～6%, ferrum 1～3%, copper 5～
8%, titanium 1～1.5%, zinc 2-5%, chromium 0.1-0.5%, cerium 0.1～0.2%；Surplus is the impurity of aluminum and content≤1%.Make
The elongation and the impact resistance that obtain aluminium alloy are improved, and provide a kind of new approaches for alloy product field.
Summary of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of aluminium alloy and preparation side thereof
Method.
It is achieved particular by techniques below scheme:
