Aluminum profile refers to a solid straight aluminum alloy profile with a certain cross-sectional shape and size after plasticity, extrusion processing and forming based on aluminum with a certain amount of other alloying elements. The profile has a wide variety of specifications and a wide range of uses, which occupies a very important position in industrial production.
Characteristics of aluminum profile
Corrosion resistanceThe density of aluminum profile is only 2.7g/cm3, which is about 1/3 of the density of steel, copper or brass (7.83g/cm3, 8.93g/cm3, respectively). Under most environmental conditions, including air, water (or salt water), petrochemical and many chemical systems, aluminum can show excellent corrosion resistance.
High conductivity
Aluminum profile is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is close to 1/2 of copper.
High 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, and automobile cylinder heads and heat sinks.
Non-ferromagnetic
Aluminum profiles are non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials.
Excellent processability
The workability of the aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states these alloys have after being produced, the CNC machining characteristics vary considerably, which requires special machine tools or technology.
Malleability
The specific tensile strength, yield strength, ductility and corresponding work hardening rate dominate the change in allowable deformation.
Recyclability
Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost indistinguishable from primary aluminum.
Types of aluminum processed materials
In the 21st century, KangDing aluminum processing industry has closely combined with the needs of the market and scientific development, so that traditional aluminum processing profiles have gradually completed the transformation to modern aluminum processing materials. Therefore, the variety of KangDing aluminum processing profiles has undergone tremendous changes. The important feature of KangDing aluminum processing profile is the development of high performance, high precision, energy saving and environmental protection. Many products have become well-known brands at home and abroad and enjoy a high reputation in the domestic and foreign markets; The quality of products has been steadily improved, and the level of product standards has been in the international advanced ranks. In addition to producing according to national standards, all major aluminum profile manufacturers can directly accept orders according to the world's advanced national standards. This indicates KangDing aluminum profile production has been further internationalization, but also for the national economy and science and technology to meet the various needs of the sophisticated aluminum, aluminum fabrication enterprises KangDing has instituted a number of internal technical delivery standards.
There are about 300 alloys and 1500 varieties of aluminum processed aluminum profiles in China, which is one of the countries with the richest product varieties in the world. Among the numerous varieties of aluminum processing materials, a large number of international advanced products and national brand-name products have emerged, representing the mainstream direction of the development and application of modern aluminum processing technology in my country.
my country's industrial aluminum profiles account for about 30% of the total applications of profiles. Mainly used in transportation industry (including automobile manufacturing industry, rail transit industry), equipment and mechanical equipment manufacturing industry, durable consumer goods industry (including light industry), etc., accounting for about 10%, 10% and 12% of my country's profile applications respectively . In the same period, the proportion of aluminum profile consumption in Europe, North America and Japan reached 60%, 55% and 40%, which is much higher than that of my country. It is estimated that in the next 5-10 years, the consumption of industrial aluminum profiles in my country will continue to grow, and the proportion of aluminum profile products will rise from about 30% to about 45-50% in 2015.
