Abstract
The invention discloses a high-compactness die-cast aluminum alloy and relates to the technical field of aluminum alloys. The high-compactness die-cast aluminum alloy consists of the following components in percentage by weight: 10-12.5% of Si, less than or equal to 0.6% of Cu, less than or equal to 0.2% of Zn, less than or equal to 0.6% of Mn, 0.1-0.6% of Mg, 0.05-0.15% of Ti, 0.01-0.02% of Sr, less than or equal to 0.15% of Cr, 0.6-1% of Fe, 0.05-0.15% of a rare earth element, less than 0.1% of other impurities, and the balance of Al. By adopting the high-compactness die-cast aluminum alloy disclosed by the invention, the problem that the existing die-cast aluminum is low in compactness is solved.
Description
Technical field
The present invention relates to technical field of aluminum alloy technology, especially a kind of high compactness aluminium diecast alloy.
Background technology
Aluminium alloy is common lightweight metal material, it is widely used in the industry such as automobile, boats and ships, space flight, machinery, communication, it has the features such as good processability, quality be light, and along with lightweight and the low consumed requirement of the energy, the demand of aluminium alloy constantly expands.Aluminium diecast alloy is a kind of aluminium alloy obtained by pressure die casting mode, and this aluminium diecast alloy can be used for producing complex-shaped workpiece, and its cost is low, therefore application is very general.At present, the compactness of aluminium diecast alloy more and more comes into one's own, and compactness is high, is conducive to improving mechanical property, but the spilehole that existing aluminium diecast alloy ubiquity is more, this has had a strong impact on the compactness of aluminium diecast alloy.
Summary of the invention
The object of this invention is to provide a kind of high compactness aluminium diecast alloy, it can solve the low problem of existing die casting aluminium compactness.
In order to solve the problem, the technical solution used in the present invention is: a kind of high compactness aluminium diecast alloy is made up of the component of following weight percentage: Si10-12.5%, Cu≤0.6%, Zn≤0.2%, Mn≤0.6%, Mg0.1-0.6%, Ti0.05-0.15%, Sr0.01-0.02%, Cr≤0.15%, Fe0.6-1%, rare earth element 0.05-0.15%, other impurity gross weight is less than 0.1%, and surplus is Al.
In the technical scheme of above-mentioned high compactness aluminium diecast alloy, technical scheme can also be more specifically: Si11.2%, Cu0.3%, Zn0.1%, Mn0.4%, Mg0.4%, Ti0.05%, Sr0.015%, Cr0.05%, Fe0.8%, rare earth element 0.01%.
Further, described rare earth element is lanthanide rare.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: the compactness that effectively improve aluminium diecast alloy by the content controlling alloy compositions, the alloy flowability of gained is good, and plasticity is high.
