Description: 【Durable & Heat Treatable】The aluminum sheet is made of high-quality 6061-T651 aluminum alloy, with high hardness, corrosion resistance, excellent processing performance and welding performance and good oxidation effect. The hardness of 6061 is stronger than that of 5052 and 3003 series aluminum plates, which is very suitable for hardness processing conditions. 【Flat & Smooth Cutting Surface】All the aluminum plates are precisely cut and the surfaces are processed to be smooth and flat with no crack or airhole.
