Abstract
The invention provides an aluminum alloy rail. The aluminum alloy rail is composed of, by weight, 1.2 to 1.8 parts of Cu, 1.6 to 2.6 parts of Mg, 0.1 to 0.4 part of Mn, 3 to 5 parts of Zn and the balance Al. The aluminum alloy rail mainly comprises Al-Mg alloy and Al-Mn alloy and is good in corrosion resistance and easy to machine, form and weld, a guide rail profile high in mechanical performance, rust resistance and corrosion resistance can be obtained after extrusion, quenching, drawing and manual aging, and the aluminum alloy rail completely meets the use requirements of the fields of aviation, aerospace, automobiles, mechanical manufacturing, ships, the chemical industry and the like.
Description
Technical field
The present invention relates to a kind of field of aluminum alloys, particularly a kind of aluminum alloy rail.
Background technology
At present, aluminium alloy has been most widely used structural metallic materials in industry, and it widely applies in Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry.But the aluminum alloy materials of existing composition proportion, its bad mechanical property, antirust, non-corrosibility is weak, so be badly in need of a kind of aluminum alloy materials of high-quality in orbit.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes a kind of mechanical property high, aluminum alloy rail that antirust, non-corrosibility is strong and preparation method thereof.
The technical problem to be solved in the present invention is achieved through the following technical solutions.The present invention is a kind of aluminum alloy rail, is characterized in, is grouped into: Cu1.2-1.8 by the one-tenth of following weight percent; Mg1.6-2.6; Mn0.1-0.4; Zn3-5; Surplus is Al.
In a kind of aluminum alloy rail technical scheme of the present invention, preferred technical scheme feature is further:
1, be grouped into by the one-tenth of following weight percent: Cu1.4-1.6; Mg2-2.4; Mn0.1-0.3; Zn3-4; Surplus is Al;
2, be grouped into by the one-tenth of following weight percent: Cu1.5; Mg2.2; Mn00.2; Zn3.5; Surplus is Al;
The technical problem to be solved in the present invention is achieved through the following technical solutions.The present invention is a kind of preparation method of aluminum alloy rail, is characterized in, aluminium alloy through extruding, quenching, stretch, artificial aging obtains that tensile strength is 500-700MPa, extensibility is 10%-14%, Brinell hardness is the guide rail section of 120-160.
In preparation method's technical scheme of a kind of aluminum alloy rail of the present invention, preferred technical scheme feature is further:
1, the tensile strength of described guide rail section is 600MPa, extensibility is 12%, Brinell hardness is 140;
2, described guide rail section is the I-beam be made up of top board, web plate and back plate, the conical bottom board that described base plate is big up and small down.
Compared with prior art, mainly Al-Mg and Al-Mn alloy in aluminum alloy rail of the present invention, its solidity to corrosion is good, be easy to shape and weld, mechanical property can be obtained high after extruding, quenching, stretching, artificial aging, the guide rail section that antirust, non-corrosibility is strong, meets the service requirements in the fields such as Aeronautics and Astronautics, automobile, machinofacture, boats and ships and chemical industry completely.
