Abstract
The present invention relates to a kind of hot-finished tubing aluminium alloy containing magnesium, its composition includes by mass percentage, 1.8% 2.1% magnesium, 0.1% 0.15% silicon, 0.2% 0.3% iron, 0.01 0.03% yttrium, 0.17% 0.20% chromium, 0.001% 0.003% titanium, 0.003% 0.015% boron, remainder is aluminium and inevitable impurity.In hot procedure tensile strength compared with aluminium alloy containing magnesium improve a lot.
Description
Technical field
The invention belongs to field of alloy material, more particularly to a kind of hot-finished tubing aluminium alloy containing magnesium.
Background technology
With the lightweight for requiring vehicle part, substitute steel product using the manufactured part of aluminium alloy and be increasingly becoming often
State.But it is bad using the effect of casting or molding for some thin-gage goods, and be made aluminium alloy using extension processing mode
During the part of complicated shape, easily there is material cracks problem in the Cold-forming process for using in the past.
Therefore, it is taken seriously using hot-working method.But the coarse grains of the existing aluminium alloy containing magnesium for using, can cause anti-tired
Labor intensity decreases.Also when aluminium alloy wall is extended processing or hole machined, intensity can be caused to decline.And it is existing containing magnalium
Alloy can not meet processing request when hot-working is carried out.
The content of the invention
It is an object of the invention to provide a kind of aluminium alloy containing magnesium material, can in hot procedure proof strength.
The present invention is achieved by the following technical solutions：
A kind of hot-finished tubing aluminium alloy containing magnesium, its composition includes by mass percentage, the magnesium of 1.8%-2.1%,
The silicon of 0.1%-0.15%, the iron of 0.2%-0.3%, the chromium of 0.17%-0.20%, the yttrium of 0.01-0.03%, 0.001%-
0.003% titanium, the boron of 0.003%-0.015%, remainder is aluminium and inevitable impurity；The wherein quality of boron and titanium
Than being 1: 1-1: 5.
The crystallization particle diameter of the hot-finished tubing almag is below 300 μm.
The tensile strength of the hot-finished tubing almag is 210-305MPa.
The yield strength of the hot-finished tubing almag is 101-130MPa.
When hole area rate is below 2.0% after processing, wall thickness is average to hot-finished tubing almag after processing
Between the 85%-90% of wall thickness.
Present invention beneficial effect compared with the existing technology is：
Tensile strength of the invention compared with aluminium alloy containing magnesium improve a lot, especially in hot procedure,
Because add that the titanium and chromium of grainiess can be reduced in the alloy, crystal grain diameter has substantial degradation in alloy.
Specific embodiment
Technical scheme, following examples are illustrated below by way of specific embodiment simply to illustrate that the present invention
Rather than restriction the scope of the present invention.
A kind of hot-finished tubing aluminium alloy containing magnesium, its composition includes by mass percentage, the magnesium of 1.8%-2.1%,
The silicon of 0.1%-0.15%, the iron of 0.2%-0.3%, the chromium of 0.17%-0.20%, the yttrium of 0.01-0.03%, 0.001%-
0.003% titanium, the boron of 0.003%-0.015%, remainder is aluminium and inevitable impurity；The wherein quality of boron and titanium
Than being 1: 1-1: 5.
The crystallization particle diameter of the hot-finished tubing almag is below 300 μm.
The tensile strength of the hot-finished tubing almag is 210-305MPa.
The yield strength of the hot-finished tubing almag is 101-130MPa.
When hole area rate is below 2.0% after processing, wall thickness is average to hot-finished tubing almag after processing
Between the 85%-90% of wall thickness.
