Description
Technical field
The present invention relates to field of aluminum alloys, the aluminium alloy of a kind of high-strength high-tractility.
Background technology
Aluminium alloy owing to having the features such as high intensity, high tenacity, light structures, corrosion-resistant, processability good, is easily recycled,
It it is metal material that modern society is pursued, most promising.It is widely used in the civilian and armies such as traffic, building materials, Aeronautics and Astronautics
Work field, has irreplaceable important function in national economy and national defense construction.Development of the West Regions, modern railway transportation,
Under the application backgrounds such as bridge, large span, high load, extra-high type building window and curtain wall need one to have higher-strength and good
The material of good elongation percentage, 6061 aluminium alloy processing characteristicies and elongation percentage etc. can not meet this requirement.ALcoa company of the U.S.
Once preparing 6013 aluminium alloys, this aluminium alloy has higher intensity and good corrosion resistance.But owing to 6013 aluminium alloys extend
Rate is low, processing characteristics is not good enough, so its application is constantly subjected to limit.
Summary of the invention
It is an object of the invention to provide the aluminium alloy of the high-strength high-tractility of a kind of low cost, good combination property, with
The problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme:
The aluminium alloy of a kind of high-strength high-tractility, is grouped into according to the one-tenth of mass percent by following: Si 5 ~ 5.5%,
Mg 0.02 ~ 0.08%, Fe 0.6 ~ 0.7%, Bi 0.5 ~ 0.55%, W 0.05 ~ 0.08%, Ti 0.02 ~ 0.09%, surplus is Al.
As the further scheme of the present invention: the aluminium alloy of described high-strength high-tractility, by following according to percent mass
The one-tenth of ratio is grouped into: Si 5.2 ~ 5.3%, Mg 0.04 ~ 0.06%, Fe 0.63 ~ 0.67%, Bi 0.52 ~ 0.54%, W 0.06 ~
0.07%, Ti 0.05 ~ 0.07%, surplus is Al.
As the further scheme of the present invention: the aluminium alloy of described high-strength high-tractility, by following according to percent mass
The one-tenth of ratio is grouped into: Si 5.25%, Mg 0.05%, Fe 0.65%, Bi 0.53%, W 0.065%, Ti 0.06%, and surplus is Al.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention based on Al-Si alloy, add appropriate Mg, Fe, Bi, W, Ti so that the combination property of the present invention is excellent
Good: under room temperature, tensile strength is between 450 ~ 520MPa, yield strength is 285 ~ 375MPa, and Brinell hardness is 135 ~ 160, elongation
Rate is 15.8 ~ 18.8%, wear rate 1.15*10-9~1.82*10-9 g·mm-1·N-1.Ensure that the present invention has higher tension
Intensity and yield strength.Owing to the casting temperature of aluminium alloy is low, extrusion technique comparative maturity, continuous extrausion process can be used to prepare,
Thus production cost is relatively low.
