Don't know how to choose high-quality aluminum profiles?
2025-09-28
When purchasing high-quality aluminum profiles, we often wonder what type to choose. Actually, there's a lot to learn about aluminum profiles. Below is some helpful information about aluminum profiles, hoping it will help you avoid wasting money. 1. Basic Properties of Aluminum Aluminum, a silvery-white metal, is the most abundant metal element in Earth’s crust (~8.3% by mass). It forms a protective oxide film in moist air, enhancing corrosion resistance though it may dull over time when exposed. With a low relative density of 2.7 g/cm³, it is lightweight; it melts at 660.37°C and boils at 2327°C. Boasting high specific strength (excellent strength-to-weight ratio), good electrical conductivity (second only to silver and copper, ideal for high-voltage lines), and exceptional thermal conductivity (~3x iron’s, suited for radiators), it also excels in reflectivity (for mirrors/coatings) and oxidation resistance, reinforced by its oxide layer. 2. Types Profiles: high-quality aluminum profiles, aluminum tubes, aluminum bars, etc. Sheets: Aluminum sheet, aluminum foil, aluminum strip (coil) Castings: Aluminum castings, aluminum pellets 3. Commonly Used Grades The first digit of the grade indicates the aluminum alloy series,...
