3A21 Aluminum Sheet
3A21 aluminum sheet is the most widely used anti-rust aluminum. Its alloy parameters are almost the same as those of 3003 aluminum. Many customers in Yongsheng export require 3A21 aluminum. Yongsheng Aluminum was founded in 1999 with a factory area of 380,000 square meters. It specializes in the production of aluminum coil, aluminum sheet, aluminum foil, aluminum strip, aluminum circle, color aluminum, embossed aluminum, mirror aluminum and other products. Our product categories cover 1-8 series alloy grades, it undertakes large-scale project orders, and global annual export volume reaches 300,000 tons.
Product Introduction
The strength of 3A21 aluminum sheet is not high, only slightly higher than industrial pure aluminum. It cannot be heat treated. Cold working is often used to improve its mechanical properties. In the annealed state, it has high plasticity, good corrosion resistance, and machinability. bad. Mainly used in fields that require plasticity and weldability.
