Description
Technical field
The present invention relates to a kind of aluminium alloy and casting method.
Background technology
Aluminium alloy is most widely used a kind of non-ferrous metal structural material in industry, in Aeronautics and Astronautics, automobile, machinery
Widely applied in manufacture, ship and chemical industry.The rapid development of industrial economy, to the demand day of Welded structural member
Benefit increases, and the Research on Weldability enabled aluminum alloy to is also goed deep into therewith.Aluminium alloy density is low, but intensity is higher, near or above excellent
Matter steel, plasticity is good, can be processed into various section bars, has excellent electric conductivity, thermal conductivity and corrosion stability, industrially widely uses,
Usage amount is only second to steel.Some aluminium alloys can use heat treatment to obtain good mechanical performance, physical property and corrosion resistance
Energy.Duralumin, hard alumin ium alloy category AI-Cu-Mg systems, typically contain a small amount of Mn, and heat-treatable strengthened is characterized in that hardness is big, but plasticity compared with
Difference.Superduralumin category Al-Cu-Mg-Zn systems, it is heat-treatable strengthened, it is intensity highest aluminium alloy but corrosion-resistant at room temperature,
Hot mastication is fast.Forging aluminium alloy is mainly Al-Zn-Mg-Si systems alloy, although addition element species is more, content is few, thus
With excellent thermoplasticity, suitable forging, therefore also known as reflectal.Existing aluminium alloy crackle is more, and elongation percentage is poor.

0.1%th, chromium≤0.1%, titanium≤0.01%, surplus are aluminium.
Further, the rare earth ferrosilicon alloy includes following component percentage by weight：Rare earth 15%-31%, silicon 30%-
41%, manganese 4%-10%, calcium 5%-8%, titanium 5%, remaining is iron.
Further, the casting method of the aluminium alloy, it is characterised in that：Its manufacture method comprises the following steps：
(1) melting aluminium first, removes waste residue；
(2) temperature is risen to 1450 DEG C -1570 DEG C, adds rare earth ferrosilicon alloy；
