Material characteristics of aluminum profiles

Aluminum alloy has low density, but relatively high strength, approaching or surpassing high-quality steel. It has good prospects and can be processed into various profiles, with excellent conductivity, thermal conductivity, and corrosion resistance. It is widely used in industry, and its usage is only second to that of steel. The specifications of T-shaped profiles can be mainly divided into 15 series, 20 series, 30 series, 40 series, 45 series, 50 series, 60 series, 80 series, 90 series, 100 series, etc. These numbers represent the cross-sectional width of the profiles, and 15 series represents industrial aluminum profiles with a loading surface width of 15mm.

The 30 series and 40 series shoulder profiles are the most widely used. The 30 series includes 3030, 306030030120, etc. The 40 series includes 40404060.408040120.41604040, etc. The use of various specifications varies in places where they are not available. The 30 series is generally used for light equipment, while the 40 series is used for ordinary equipment. Each specification of industrial aluminum profile also has a thin or thick wall thickness. Thick ones have high prices and high load-bearing capacity, and each type of product can be classified into political and national standards. The main difference between European standards and international standards is the mouth. The European standard groove is trapezoidal, while the national standard is rectangular.

The density of aluminum profiles is only 2.7g/cm3, which is approximately 7.83 gcm3 for steel, 8.93 gcm3 for copper, or brass, respectively. Under most environmental conditions, including air, water, or water, petroleum chemistry, and many chemical systems, aluminum can exhibit excellent corrosion resistance.
