The main material of 3003 aluminum coil is aluminum-manganese alloy, has a good anti-corrosion on atmosphere, brine, freshwater, gasoline, etc., ranking first in corrosion resistance, is the best anti-corrosion material on aluminum product.
The strength of 3003 aluminum alloy coil is not high, the slightly higher strength one are used in industrial pure aluminum, it can not be hardening by heat treatment, usually use the cold processing methods to improve its mechanical properties. 3003 aluminum alloy coil has a high plasticity in the annealed state, a good plasticity in the semi-cold hardening, and a good weldability but a poor machinable performance. 3003 aluminum alloy coil widely used in processing parts or components that needs a good formability, high corrosion resistance and good weldability, like kitchenware, food and chemical processing and storage devices, tanks and cans for transporting liquid products, and a variety of pressure vessels and pipes processed with sheet metal.
Hollow aluminum made of 3003 aluminum alloy coil is one of the necessary materials for insulating glass, its quality is directly related to the effect, service life and thermal insulation function of insulating glass. The main role of 3003 aluminum alloy coil is to separate evenly and support two or more pieces of glass and. Hollow glass is made of high purity aluminum for raw materials, after dozens of craft process, with a flat surface, non-oxidizing and non-corrosive, desiccant has no effect on it, eliminate atomization phenomenon effectively. Hollow aluminum is new type of environmentally friendly building materials products, and has vast market
