Description
Technical field
The present invention relates to a kind of high-strength heat-resisting aluminum-alloy.
Background technology
It is big that aluminium has reserves, density is little, and plurality of advantages such as specific tenacity height, good conductivity make aluminium and aluminium alloy thereof not only in war industrys such as Aeronautics and Astronautics, naval vessels, and in civilian industries such as building materials, household electrical appliances, telecommunications and power cable, occupy critical role, play a part to become more and more important.High-strength heat-resisting aluminum-alloy is to have the aluminium alloy that advantages of higher tensile strength has fine resistance toheat again.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-strength heat-resisting aluminum-alloy.
For solving the problems of the technologies described above, the present invention realizes like this
High-strength heat-resisting aluminum-alloy comprises following element by weight percentage: the aluminium of copper 1-5%, manganese 0.5-1.0%, titanium 0.1-0.5%, iron 0.1-0.3%, silicon 0.1-0.3%, magnesium 0.01-0.05, zinc 0.01-0.05, zirconium 0.1-0.5%, nickel 0.01-0.05%, tin 0.01-0.05%, indium 0.35-0.75% and surplus.
Copper can improve intensity, the hardness of aluminium alloy, but can reduce extensibility;
Manganese, zirconium, indium can increase the recrystallize humidity of aluminium alloy, improve processibility, opourability and the welding property of aluminium alloy;
Titanium, boron can crystal grain thinnings, and the processing of control casting original state is with grain fineness number and shape in the ingot casting,
Iron can increase DIMENTIONAL STABILITY and support performance, makes it at high temperature have high strength, hardness, but excessive iron and copper form the Cu2FeA7 component and reduces the required copper amount of annealing effect;
Silicon combines with iron, prevents that iron from combining the tensile property that reduces alloy with copper;
Magnesium can improve the molten admittedly thermal treatment of X alloy and the intensity of the back alloy that quenches, and makes aluminium alloy at room temperature have higher intensity and extension performance, but can reduce tensile strength.Addition element magnesium can improve the intensity of alloy system in zinciferous aluminium alloy, because of magnesium and zinc formation MgZn.But can reduce the overall corrosion resistance of aluminium, can overcome this shortcoming by adding copper or chromium;
Nickel, the solid solubility in aluminium is no more than 0.04%, if greater than 0.04%, nickel is insoluble intermediate metal, and many and iron combines, and can improve the intensity of fine aluminium, but reduce its ductility; Tin can strengthen artificially aged effect after the aluminium alloy solution heat treatment greatly, makes alloy strength increase, and erosion resistance improves, and the nickel of high level causes the alloy thermal crack, exists simultaneously if any small amount of magnesium, and then the artificially aged feature just obviously weakens.
It is 150-250MPa that the aluminum alloy heat that the present invention obtains is handled back tensile strength, and elongation is 2-8%, and Bu Shi intensity is 100-150HBS.The alloy that the present invention obtains is a high strength thermal resistant alloy, can be widely used in the Aeronautics and Astronautics industry.
