Description
Technical field
The present invention relates to metal material field, and in particular to a kind of aluminium alloy ingots.
Background technology
Aluminium alloy, it is the alloy that one or more alloying element compositions are then added using aluminium as matrix element.Aluminium alloy
Density is low, but intensity is higher, and with excellent electric conductivity, thermal conductivity and corrosion stability etc. so that aluminum alloy materials are in electricity
Lixing industry has obtained relatively broad application.
Aluminium alloy is the extension product of fine aluminium, and the density of fine aluminium is small (ρ=2.7g/m3), about the 1/3 of iron, and fusing point
Low, about 660 DEG C or so, aluminium is face-centred cubic structure, therefore has very high plasticity (δ:32~40%, ψ:70~90%), because
This its it is easy to process, can be made into various section bars, sheet material, and corrosion resistance is good.But the intensity of fine aluminium is very low, therefore should not make knots
Structure material.By long-term production practices and scientific experiment, people gradually with add alloying element and be heat-treated the methods of
Carry out reinforced aluminum, this has just obtained a series of aluminium alloy.
Aluminium alloy density is low, but intensity is higher, and near or above high-quality steel, plasticity is good, therefore casting class product makes more
With aluminium alloy, existing aluminium alloy is easily cracked and corrodes.
The content of the invention
The technical problem to be solved in the present invention is in view of the shortcomings of the prior art, provide a kind of combination property preferable, corrosion resistant, property
The stable aluminium alloy ingots of energy.
To solve above-mentioned technical problem, technical scheme provided by the invention is：
