Aluminum alloy profiles are widely used in construction, aviation, railways, automobiles, motorcycles, ships, electronics, machinery, chemicals, furniture and other fields.

It mainly plays the role of support, fixation, partition and decoration. Aluminum alloy profile has the characteristics of light weight, high strength, corrosion resistance, convenient processing and transplantation, and beautiful atmosphere, so it has become one of the most widely used materials in the construction field.

At the same time, the material can be recycled and meets the requirements of environmental protection, so it is favored by people more and more.

aluminium alloy extrusions

The alloy composition can be divided into aluminum profiles of various alloy brands, and the difference between different brands is that the proportion of various metal components is different. Aluminum profiles are mainly made of three metal materials: aluminum, magnesium and silicon.

Generally, domestic aluminum profiles are widely used, such as protective cover, workbench, laser room, etc. Their differences lie in different uses, different overall shapes and different cross-sectional shapes of aluminum profiles used, but they are all produced by hot melt extrusion and then connected by some accessories.

The section size of aluminum profiles is divided into several series, commonly used are 20 series, 30 series, 40 series, 45 series, 50 series, 60 series, 80 series, 90 series and 100 series.

There is also a profile, which is mainly processed according to the actual drawings of customers. Each series contains several sections, and the larger the section, the better the bearing capacity.

What are the performance characteristics of industrial aluminum profiles?

Industrial aluminum profile is an alloy material with aluminum as the main component. Aluminum bars can be obtained with different cross-sectional shapes by hot melting and extrusion. However, the mechanical properties and application fields of industrial aluminum profiles are different with different proportions of added alloys.

Generally speaking, industrial aluminum profiles refer to all aluminum profiles except those used for building doors and windows, curtain walls, indoor and outdoor decoration and building structures.

aluminum profile system

erosion resistance

The density of aluminum profile is only 2.7g/cm3, which is about 1/3 of that of steel, copper or brass (7.83g/ cm3 and 8.93g/ cm3 respectively). In most environmental conditions, including air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.

electrical conductivity

Aluminum profiles are often selected because of their excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.

Thermal conductivity rate

The thermal conductivity of aluminum alloy is about 50-60% of that of copper, which is beneficial to the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, cylinder heads and radiators of automobiles.

Nonferromagnetic

Aluminum profiles are non-ferromagnetic, which is an important characteristic for electrical and electronic industries. Aluminum profiles cannot spontaneously ignite, which is important for applications involving handling or contact with flammable and explosive materials.

Machinability

Machinability of aluminum profiles is excellent. In all kinds of wrought aluminum alloys and cast aluminum alloys, and in all kinds of states after these alloys are produced, the machining characteristics change greatly, which requires special machine tools or technologies.

Formability

Specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the variation of allowable deformation.
