Abstract

The invention provides a magnalium alloy material. The magnalium alloy material comprises, by weight, 10%-25% of magnesium, 1.5%-3% of silicon, 0.3%-1% of manganese, 0.01%-0.1% of copper, 0.03%-0.35% of titanium, 0.05%-0.4% of zinc, 0.005%-0.04% of carbon, 0.005%-0.035% of iron, and the balance aluminum and few impurities. The magnalium alloy material has excellent mechanical strength and toughness, and meanwhile the defects such as breakage, wrinkles and fatigue are avoided in the machining process; in addition, the preparation method is easy, the production efficiency is improved, the labor intensity and the production cost are reduced, and the service life of the material is prolonged.

Description

A kind of magnesium-aluminium alloy material

Technical field

The present invention relates to technical field of metal, be specifically related to a kind of magnesium-aluminium alloy material.

Background technology

Aluminium alloy is a most widely used class non-ferrous metal structured material in industry, and the density of fine aluminium is little, and be only 1/3 of iron, fusing point is low.Aluminium is face-centred cubic structure, has very high plasticity, and be easy to processing, can be made into various section bar, sheet material, corrosion resistance is good; But the intensity of fine aluminium is very low, structured material should not be made.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.

Magnalium traditional at present, due to the restriction of material, in the course of processing, easily occur the defects such as fracture, wrinkle, fatigue, yield rate is lower, result in the waste of material.Meanwhile, production efficiency is lower, adds labour intensity, adds production cost.

Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.

Summary of the invention

The object of this invention is to provide and a kind of there is excellent wear resistance, the magnesium-aluminium alloy material of ductility.

The present invention is achieved through the following technical solutions:

A kind of magnesium-aluminium alloy material, comprises the raw material composition of following weight percent content:

Magnesium 10% ~ 25%;

Silicon 1.5% ~ 3%;

Manganese 0.3% ~ 1%;

Copper 0.01% ~ 0.1%;

Titanium 0.03% ~ 0.35%;

Zinc 0.05% ~ 0.4%;

Carbon 0.005% ~ 0.04%;

Iron 0.005% ~ 0.035%;

Surplus is aluminium and a small amount of impurity.

Magnesium 12% ~ 25%;

Silicon 1.5% ~ 2.5%;

Manganese 0.4% ~ 1%;

Copper 0.025% ~ 0.1%;

Titanium 0.05% ~ 0.3%;

Zinc 0.05% ~ 0.25%;

Carbon 0.005% ~ 0.04%;

Iron 0.01% ~ 0.035%;

Surplus is aluminium and a small amount of impurity.

Further, the molybdenum that weight percent is 0.05% ~ 0.25% is also comprised.

Further, the scandium that weight percent is 0.03% ~ 0.4% is also comprised.

The invention has the beneficial effects as follows: magnalium proposed by the invention has excellent physical strength, and toughness is high, simultaneously, avoid occurring the defects such as fracture, wrinkle, fatigue in the course of processing, and preparation method is simple, improve production efficiency, reduce labour intensity of knowing clearly, reduce production cost, improve the work-ing life of material.
