Abstract
The invention relates to a magnesium-aluminium alloy material. The magnesium-aluminium alloy comprises, by weight, 8.9%-9.2% of Al, 0.19%-0.25% of Mn, 0.65%-0.75% of Zn, 0.035%-0.05% of Si, 0.015%-0.025% of Cu, less than 0.002% of Ni, less than 0.003% of Fe, less than 0.0015% of Be, and the balance being Mg. The magnesium-aluminium alloy material provided by the invention can effectively reduce generation of waste residues and increase product yield.
Description
Technical field
The present invention relates to Material Field, espespecially a kind of magnesium-aluminium alloy material.
Background technology
The damping performance that magnesium-aluminium alloy material has light weight, hard, corrosion resistance nature is strong, thermal diffusivity is good and good, is widely used in various industry in recent years, as cell phone, removable computer, automobile etc.Particularly in field of mobile phones; the application of magnesium-aluminium alloy material not only can increase metal-like; improve Consumer's Experience effect; simultaneously along with the development trend of mobile phone giant-screen; need the center of a high strength to protect large-sized touch-control display panel, avoid touch-control display panel shaking or easy cracked malfunctioning problem in slightly falling.
Current AZ91D magnesium ingot aborning mostly adopts GB or ASTM B94-94a to formulate, and two standard management and control a wider range, be applicable to the processing of a variety of industry product, but on concrete industry specific product, there will be again different problems, such as in the die casting of mobile phone center and computer fittings is produced, the problem that die casting waste residue is more can be run into, wasting while, waste residue also have impact on the quality effect of product, directly reduce the yield of product, affect the surface smoothness of product, add labour intensity and the complexity of process of surface treatment.
Summary of the invention
The object of the present invention is to provide in a kind of press casting procedure the magnesium-aluminium alloy material producing waste residue few, effective raising product surface smooth finish.
For solving the problems of the technologies described above, the invention provides a kind of magnesium-aluminium alloy material, by weight percentage, comprise Al 8.9%-9.2%, Mn 0.19%-0.25%, Zn 0.65%-0.75%, Si 0.035%-0.05%, Cu 0.015%-0.025%, Ni<0.002%, Fe<0.003%, Be<0.0015%, remaining Mg.
The weight percent that in described magnesium-aluminium alloy material, remaining often plants impurity does not surpass 0.02%.
Magnesium-aluminium alloy material of the present invention is when spare parts such as Die Casting mobile phone centers, and more existing formula can reduce by the waste residue of 70%, has saved material cost, the more important thing is the minimizing of producing waste residue, drastically increase product surface smooth finish, reduce process of surface treatment, improve product yield.
Embodiment
Magnesium-aluminium alloy material formula of the present invention is (weight percent): Al 8.9%-9.2%, Mn 0.19%-0.25%, Zn 0.65%-0.75%, Si 0.035%-0.05%, Cu 0.015%-0.025%, Ni<0.002%, Fe<0.003%, Be<0.0015%, remaining Mg.Requirement in above-mentioned formula, all the other impurity are often planted weight ratio and are not surpassed 0.02%.
Adopt the magnesium-aluminium alloy material of above-mentioned formula in the spare part processes such as Die Casting mobile phone center, more existing formula can reduce by the waste residue of 70%, save material cost, the more important thing is the minimizing of producing waste residue, drastically increase product surface smooth finish, reduce process of surface treatment, improve product yield.
