Haomei Industrial Co., Ltd has been engaged in the aluminum sheet manufacturing, and the series arranges from one series to the eight series, and the different series are of the different characters, today, we will introduce you one of it- the 3A21 aluminum sheet. The thickness of it is 0.2-4.5, and the width is 100-2600, and the length is 500-16000. The 3A21 aluminum plate sheet is a kind of widely used anti rust aluminum, the intensity is not high (only slightly higher than that of pure aluminum), can be strengthened by heat treatment, so we often use cold processing methods to improve its mechanical properties; in the annealed state have high plasticity, in the semi cold hardening plastic is good, when the low plasticity of cold hardening, good corrosion resistance, good weld ability, poor machine ability. The 3A21 aluminum sheet has many advantages, first, 3A21 aluminum plate sheet is a typical antirust aluminum, with excellent corrosion resistance, can adapt to the humid environment; Second, it has good weld ability, good tensile strength, elongation is better than 3003 aluminum plate 25%; Third, it has smooth surface, good plasticity, pressure resistance; Fourth, the company has a semi continuous casting production line of 6, continuous casting and rolling production line of the 10, other large-scale processing equipment 44 units, the annual output of up to 450 thousand tons. 

Haomei has been engaged in the aluminum product manufacturing for more than 30 years, which is reliable. If you are in demand of the 3A21 aluminum sheet, please contact us!
