Abstract
The invention relates to an aluminum magnesium alloy for a heat machining pipe. The aluminum magnesium alloy comprises, by mass percent, 1.8%-2.1% of magnesium, 0.1%-0.15% of silicon, 0.2%-0.3% of iron, 0.1%-0.3% of strontium, 0.17%-0.20% of chromium, 0.001%-0.003% of titanium, and the balance aluminum and inevitable impurities. In the heat machining process, the tensile strength is greatly improved compared with an existing magnesium aluminum alloy.
Description
Technical field
The invention belongs to field of alloy material, more particularly to a kind of hot-finished tubing almag.
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 casting or the effect for molding for some thin-gage goods, and 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 aluminium alloy containing magnesium for now 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 almag, its composition includes by mass percentage, the magnesium of 1.8%-2.1%, 0.1%-
0.15% silicon, the iron of 0.2%-0.3%, the strontium of 0.1-0.3%, the chromium of 0.17%-0.20%, 0.001%-0.003%'s
Titanium, remainder is aluminium and inevitable impurity.
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 after processing hole area rate is below 2.0%, 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：
The present invention tensile strength 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 is illustrated below by way of specific embodiment, following examples are simply to illustrate that the present invention
Rather than restriction the scope of the present invention.
A kind of hot-finished tubing almag, its composition includes by mass percentage, the magnesium of 1.8%-2.1%, 0.1%-
0.15% silicon, the iron of 0.2%-0.3%, the chromium of 0.17%-0.20%, the strontium of 0.1-0.3%, 0.001%-0.003%'s
Titanium, remainder is aluminium and inevitable impurity.
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 after processing hole area rate is below 2.0%, wall thickness is average to hot-finished tubing almag after processing
Between the 85%-90% of wall thickness.
