February 13, 2020

A black aluminum coil stock serves as a raw material for roofing sheets, advertising boards, cookware, interior decoration, exterior decoration, wall cladding, curtain walls and so on. It covers an extensive scope of application in numerous industries since it can be cut, bent and even drilled at random. Different shapes of black aluminum products are obtained in this way. In addition, the coil stock falls on varied alloys, rolling methods, tempers and sizes.

Cold rolled black aluminum coil stocks have a smaller grain fineness number and better structural properties than hot rolling stocks. Black stocks are actually color coated aluminum coil rolls with a black paint. Common alloys include 1050, 1060, 1070, 1100, 3003, 3004, 3005, 3104, 3105, 5005, 5052, 5083, 6061 and 6082, among which 6xxx alloys, combining advantages of 3xxx and 5xxx, enjoy the highest strength, corrosion resistance and price. 1xxx aluminum coil stocks are regarded as the pure aluminium series which display all primary physical and chemical properties of aluminum metal. 3xxx, on the other hand, boasts a longer service life with the help of manganese, the alloyed metal known for corrosion resistance stronger than aluminum. 5xxx contains magnesium that is even lighter than aluminum. As a result, the price of the three series gets higher successively.
