According to official website, an aluminum bar manufacturer, the homogenization treatment temperature of aluminum bars is about 520℃ and the treatment time is 2-4 hours. The significance of homogenization treatment of aluminum rod is to make the internal structure of aluminum rod more uniform, avoid internal defects and improve the hardness and corrosion resistance of aluminum rod. Aluminum rod is a kind of nonferrous metal rod, which has the characteristics of high strength, corrosion resistance and light weight. The classification of aluminum bars can be classified according to shape, processing method and accuracy. Common aluminum bars are square bars, round bars, patterned bars and special-shaped bars.
