Aluminum plates are widely used in products that do not require high strength. Products are commonly used in signboards, billboards, building exterior wall decoration, bus body, high-rise and factory wall decoration, kitchen sink, lamp holder, fan blade, electronic parts, chemical instruments, sheet metal processing parts, deep drawing or rotating concave utensils, welding parts, heat exchangers, clocks and nameplates, nameplates, kitchenware, decorations, reflective utensils, etc.
Look at the thickness. The thickness, strength and oxide film thickness of excellent pattern aluminum plate shall comply with national standards: aluminum plate thickness ≥ 1.2mm, tensile strength ≥ 157n / mm2, yield strength ≥ 108n / mm2, oxide film thickness ≥ 10 microns. If it does not meet the standard, it is inferior aluminum plate.
It is processed with 3003 as the main raw material. This kind of aluminum plate is also called antirust aluminum plate. Its strength is slightly higher than that of ordinary aluminum alloy checkered plate. It has certain antirust performance, but its hardness and corrosion resistance can not reach 5000 series flower board. Therefore, the product can be used for less stringent rust prevention requirements, such as truck model and cold storage floor.
Aluminum plate manufacturer, which is made of 5000 series aluminum plates (such as 5052 or 5083), has good milk corrosion, hardness and rust resistance. It is usually used in special places, such as ships and engine room lights. Aluminum plate has high hardness and certain bearing capacity.
The aluminum alloy checkered plate processed with 1060 Aluminum plate as the base material can adapt to the ordinary environment and has low price. Aluminum plates with this pattern are usually used for refrigeration, flooring and outer packaging.
Aluminum plate manufacturers second look at processing. The patterned aluminum plate produced by conventional large factories is made of smooth materials, with clear and tidy patterns, flat aluminum plate, and no defects such as oil stains, scratches and folds on the surface. Aluminum plates with patterns produced in small factories use waste aluminum as material. The surface is dull, the pattern is unclear and uneven, the board surface is uneven, the performance can not meet the standard and the quality is poor.
Third, look at the price. Patterned aluminum plate is divided into pure aluminum and alloy, and its price is naturally different. The processing cost of patterned aluminum plate produced by regular manufacturers is thousands of yuan per ton. The price of alloy is higher than that of pure aluminum. The price of aluminum plate of conventional manufacturers is about 20% - 30% higher than that of inferior aluminum plate. When purchasing, enterprises should not only compare prices. If they buy substandard products, it's too late to regret.
