Common problems and causes of 5052 aluminum sheet

5052 aluminum sheet commonly used in the appearance of electronic parts or accessories, which is widely used in aluminum products, but the production has a number of common problems, such as aluminum sheet surface defects.
The problem of the oxidation of color, black silk, sand holes and other issues of 5052 aluminum sheet oxide is how to produce and what is the reason?

There are many reasons of black silk of 5052 aluminium sheet, for example, like affiliated machine rolling oil drops on the poor management, the pressure is too large or too large in surface tension caused by indentation. If you go down the thin material rolling, these dark marks will become more and more thin and form the formation of dark or black line, sometimes it is even unclear whether oil or mark, even on the surface can not see the color difference. But after oxidation ,it is very obvious. For the customer, affirmation is to refuse if they see the inconsistent phenomenon appearance. After the oxidation, the emergence of black silk is one of the most deadly results. Once this happens, there is almost no room for survival, the loss and consequences are irreparable.
The second problem is the color difference. Generally used to make the appearance of the product, color difference is not to be. Any customer is unwilling to accept a similar “two shameless” products. To eliminate these problems, it is necessary to rely on the source column to control.
Sand hole is generally the internal structure, because of impurities in cast billets or vapor not removed, or other elements did not stir and other factors, so we should control the source of ingot casting.

5052 aluminum sheet elongs to Al-Mg alloy, cold forming has good processing performance, processing performance, good corrosion resistance, rust proof aluminum alloy 5052 is a most widely used, this alloy has high strength, especially the anti fatigue strength, ductility and high corrosion resistance, in the semi cold hard plastic is good, do not 5052 alloy used for the internal pressure of the beverage cover, the status of H19 material, do first oxidation treatment to improve coating adhesion and corrosion resistance, both sides painted after the tank cover forming processing, my company production of 5052 alloy lid material with good surface quality, stable performance.

5052 aluminum sheet of haomei aluminium is certificated to ASTM B209 and it can be cut to size at customers’ need. The primarily alloyed with magnesium and chromium which improve the strength of 5052 aluminum sheet Products with different thickness have different tensile and yield strength, as well as elongation, all of which live to international standards. plate is stronger than 1100 and 3003 and it is an excellent candidate for most processing techniques.
5052 Aluminum Alloy sheet is a medium strength alloy containing Magnesium as its major alloying element. 5052 Aluminum Alloy sheet has good workability, a high fatigue strength and is very good for welding. It has very good corrosion resistance to seawater and the marine and industrial atmosphere. Typical applications include aircraft fuel/oil lines, fuel tanks, other transportation areas, sheet metal work, appliances and lighting, wire, and rivets.
Performance advantage:
1,5052 Aluminum Alloy sheet has high plasticity, corrosion resistance, suitable for use in marine environment;
2, the surface of the Aluminum sheet without peeling, bubble, surface rough and local mechanical damage, the surface of the Aluminum sheet without cracks and corrosion spots and trace nitrate;
The company Haomei Industrial Co., Ltd. China’s largest Aluminum sheet manufacturers and suppliers, the production of 1-8 series aluminum alloy sheets to provide you with the best price and high quality services
