Aluminum alloy research and development

Aluminum alloy research and development in the early days is mainly linked with the aviation industry, only nearly a hundred years of history, but the development of fast, the scope of use continues to expand, in the metal materials in its output after steel ranked second, in the non-ferrous metal materials in the first place. Aluminum alloy will have great development: the use of updated process methods, improve the original alloy, develop new alloys, give the update more perfect performance, expand the scope of use, increase the use of.

Quality requirements for aluminum alloy doors and Windows

The surface of doors and Windows should not have obvious scratches, scratches, bruises and other defects. The coloring surface of adjacent rods should not have obvious color difference.

The selection method of aluminum alloy doors and Windows

Compared with steel and wood doors and Windows, aluminum alloy doors and Windows have the following advantages: (1) Light weight and high strength. The density is only l/3 of steel.

Grades of aluminium and aluminium alloys

The brand nominating method of pure aluminum: when the aluminum content is not less than 99.00%, it is pure aluminum, and its brand is expressed by the 1XXX series. The last two digits of the grade indicate the minimum aluminum content. When the minimum aluminum percentage is accurate to 0.01%, the last two digits of the grade are the two digits after the decimal point in the minimum aluminum percentage. The second letter of the grade indicates the modification of the original pure aluminum. If the second letter is A, it is the original pure aluminum; If it is other letters from B to Y (selected in the order of the alphabet according to international regulations), it is expressed as a modification of the original pure aluminum, and its element content is slightly changed compared with the original pure aluminum.

Quality standards for aluminum alloy doors and Windows

Take a look at the materials. High quality aluminum alloy doors and Windows used in aluminum profiles, thickness, strength and oxide film, should meet the relevant national standards, aluminum alloy window main stress rod wall thickness should be more than 1.4 mm, aluminum alloy door main stress rod wall thickness should be more than 2.0 mm, tensile strength reached 157 Newton per square meter of millimeter, yield strength to reach 108 Newton per square millimeter, Oxide film thickness should reach 10 microns. If the above standards are not met, it is inferior aluminum alloy doors and Windows, which cannot be used.

Uses of aluminium and aluminium alloys

1060:1060 is a common industrial pure aluminum, containing no less than 99.60% aluminum, which is characterized by low strength, work hardening is the only way to strengthen. Good thermal and cold processing performance, high thermal conductivity, excellent corrosion resistance. It is widely used in industrial equipment requiring good formability, corrosion resistance and weldability, and can also be used as an electrical conductor material.
