Industrial aluminium profile is a kind of alloy material with aluminium as its main component. Aluminum rods can be hot melted and extruded to obtain aluminium materials with different cross-section shapes. However, the mechanical properties and application fields of industrial aluminium profiles are different due to the different proportion of alloys added. How can we buy industrial aluminium profiles with good quality? How to judge the quality of industrial aluminium profiles is introduced.
1. Aluminum profile manufacturers-large-scale aluminium profile factories, raw materials, production process standards, strict quality control, higher processing costs than small factories, processing costs can differ by 2000-3000/ton. Reduction of 2-3 yuan/kg. In recent years, with the level of industry, the aluminium industry is becoming more and more popular. Sales are also diversified, prices are disparity. Unknown customers, only. Choose industrial aluminium sales companies from the lowest prices. This forces some companies that insist on quality first to ensure sales from lower raw materials and processing costs. Market chaos is becoming more and more obvious.
2. The chemical composition of industrial aluminium profiles can be greatly reduced by mixing a large amount of scrap aluminium, but it will lead to the unqualified chemical composition of industrial aluminium and seriously endanger the safety engineering.
3. Thickness distribution of roughly the same size drawings, as well as section size, width, central hole, but the wall thickness difference is very large, can also be quite different weight, each price also corresponds to a large gap. In addition, lower industrial aluminium can reduce some shutdown time, reduce the consumption of chemical reagents, reduce costs, but the corrosion resistance of materials. Greatly reduced.

4. Thickness of oxide film - insufficient thickness, easy to rust and corrode on aluminium surface. National standards for building and industrial aluminium oxide film thickness should not be less than 10 um (micron). Some attribute names, addresses, production licenses, certificates for industrial aluminium profiles, film thickness is 2-4 um, and some even no film. According to expert estimates, every reduction of 1 um oxide film thickness, can be Reduce power consumption by more than 150 yuan per ton of material.
