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,...

This is an article about choosing between aluminum profiles and steel. It mainly talks about which is cheaper, aluminum profiles or steel. It introduces the differences and advantages of the two from the perspectives of raw materials, processing, cost, maintenance, etc., so as to help you choose the material that meets your needs and expectations. I hope it can help those in need.   Raw Materials The raw materials for aluminum profiles are more expensive than steel. The price of aluminum ingots (approximately 20,000 yuan/ton) is higher than that of ordinary steel (approximately 5,000 yuan/ton). However, the price of high-strength aluminum alloys (such as 7075) is close to that of specialty steel. Processing Costs Aluminum profiles are primarily extruded. Compared to steel rolling, the energy consumption is only one-third of that of steel, and the processing efficiency is much higher than that of steel. Therefore, aluminum profiles are more suitable for high-end customization needs. Overall cost is similar between the two. Transportation Costs Due to the low density of aluminum profiles, they are lighter. In terms of volume, steel is...
