The cast aluminium alloy comprises the following components by weight percent: 0.2-0.5% of Si, 0.3-0.8% of Mn, 0.5-0.8% of Mg, less than 0.25% of Fe, less than 0.1% of Cu, less than 0.1% of Zn, 0.01-0.05% of Ti, 0.06-0.09% of Nb, 4.2-4.6% of Ce, 0.06-0.12% of Zr, 0.03-0.08% of Sc, less than 0.1% of total other impurities and the balance of Al. The problems that the existing cast aluminium alloys have lower heat conductivity and can not meet the development requirements of automobiles are solved by adopting the cast aluminium alloy.
Description
Technical field
The present invention relates to casting technology field, especially a kind of high heat conduction cast aluminium alloy.
Background technology
Aluminium alloy is common lightweight metal material, and it is widely used in the industry such as automobile, boats and ships, space flight, machinery, communication, and it has the features such as good processability, quality be light, energy-conservation.Along with the development along with automotive industry, automotive light weight technology and the low consumed requirement of the energy have become a megatrend of automobile industry, and the demand of aluminium alloy on automobile as lightweight first material also constantly expands.The aluminum alloy spare part being applied to automobile adopts casting mostly, and because casting is relative to other processing mode, its using rate of metal is high, and dimensional precision is high, can produce complex-shaped parts, has excellent mechanical property and physicals.The cast aluminium alloy that adopts such as current motor car engine, wheel rim is manufactured more, be conducive to like this solving heat radiation, can work-ing life of elongated component itself and the spare and accessory parts directly contacted with it, but, the heat-conductive characteristic of existing cast aluminium alloy is not ideal enough, limit the high speed of automobile and the development of superpower, in order to the demand of satisfied fast development, be necessary to develop the cast aluminium alloy with high thermal conductivity.
Summary of the invention
The object of this invention is to provide a kind of high heat conduction cast aluminium alloy, the heat-conductive characteristic that it can solve existing cast aluminium alloy is lower, cannot meet the problem of development of automobile demand.
In order to solve the problem, the technical solution used in the present invention is: a kind of high heat conduction cast aluminium alloy is made up of the component of following weight percentage: Si0.2-0.5%, Mn0.3-0.8%, Mg0.5-0.8%, Fe<0.25%, Cu<0.1%, Zn<0.1%, Ti0.01-0.05%, Nb0.06-0.09%, Ce4.2-4.6%, Zr0.06-0.12%, Sc0.03-0.08%, other impurity gross weight is less than 0.1%, and surplus is Al.
In the technical scheme of above-mentioned high heat conduction cast aluminium alloy, technical scheme can also be more specifically: Si0.35%, Mn0.58%, Mg0.6%, Fe0.08%, Cu0.05%, Zn0.04%, Ti0.2%, Nb0.09%, Ce4.4%, Zr0.09%, Sc0.06%.
Further, Si0.5%, Mn0.3%, Mg0.8%, Fe0.15%, Cu0.08%, Zn0.03%, Ti0.05%, Nb0.06%, Ce4.2%, Zr0.06%, Sc0.03%.
Further, Si0.2%, Mn0.8%, Mg0.5%, Fe0.2%, Cu0.04%, Zn0.06%, Ti0.01%, Nb0.08%, Ce4.6%, Zr0.12%, Sc0.08%.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: on the basis that ensure that castability, mechanical property and physicals, significantly improve the heat conductivility of cast aluminium alloy, thermal conductivity reaches more than 200W/mK.
