What is aluminum profile? Aluminum profile is generally a product formed by aluminum products through processing technology, which can be seen everywhere in our lives. Aluminum profiles can be formed into inherent characteristics after processing. Aluminum bars can be formed into aluminum profiles with different interfaces through coating technology and then hot melting and extrusion. Aluminum profiles have various colors and selectivity.

Characteristics of aluminum profile:

1) Corrosion 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.

2) 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.

3) thermal conductivity;

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.

4) Non-ferromagnetic;

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.

5) 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.

6) formability;

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

7) recyclability;

Aluminum is highly recyclable, and the characteristics of recycled aluminum are almost the same as those of primary aluminum.

Classification by purpose:

1. Building aluminum profiles (divided into doors, windows and curtain walls).

2. Aluminum profile of radiator.

3. General industrial aluminum profiles: mainly used in industrial production and manufacturing, such as automatic machinery and equipment, the skeleton of enclosure, and mold opening customized by companies according to their own mechanical equipment requirements, such as assembly line conveyor belt, elevator, glue dispenser, testing equipment, shelves, etc., and are mostly used in electronic machinery industry and clean room.

4. Aluminum alloy profile of rail vehicle structure: mainly used for manufacturing rail vehicle body.

5. Mount aluminum profiles, make aluminum alloy picture frames, and mount various exhibitions and decorative paintings.
