Description

The aldural of a kind of highly corrosion resistant and solderability

Technical field

The invention belongs to metal material field, refer to especially high strength, the low density aluminum alloy of a kind of highly corrosion resistant and solderability.

Background technology

Now use to manufacture various for building the product with transport trade, more especially for aerospace and the dissimilar aluminium alloy of shipping industry.

In many above-mentioned application, need to there is the alloy of performance after high strength, low density, excellent anticorrosive, superior weldability and excellent welding.

Summary of the invention

An object of the present invention is to provide there is high strength, the aluminum alloy materials of low density and excellent corrosive nature.

The present invention is achieved by the following technical solutions:

The aldural of a kind of highly corrosion resistant and solderability, it forms be the magnesium of 4.5-5.0% by weight percentage, the iron of the manganese of 0.5-1.0%, 0.1-0.3%, the copper of the silicon of 0.1-0.3%, 0.05-0.1%, the chromium of the zirconium of 0.05-0.30%, 0.05-0.3%, the scandium of the titanium of 0.05-0.1%, 0.01-0.03%, the lithium of the zinc of 0.8-1.5%, 0.05-0.3%, the tungsten of the vanadium of 0.01-0.03%, 0.001-0.0015%, 0.01-0.05% containing yttrium light rare earths, surplus is aluminium and inevitable impurity.

Described alloy at the annealing temperature of 280-310 ℃ to produce the product that includes but not limited to the temperature range that soft state, work-hardened condition or creep forming are required.

The invention has the beneficial effects as follows:

There is good mechanical property and have the low-density alloy of good erosion resistance concurrently.
