Aluminum Disk

Aluminum disk is a precision blanking material made from aluminum coils by stamping or deep drawing. It is widely used in cookware manufacturing, lighting, traffic signs, and industrial parts due to its excellent formability, lightweight, and corrosion resistance.

Aluminum disks are ideal for applications requiring deep drawing or spinning. The product features smooth surfaces, burr-free edges, uniform thickness, and high thermal conductivity, making it the preferred raw material in multiple manufacturing fields.

What is Aluminum Disk?

An aluminum disk is a flat, round alloy raw material produced by cutting or punching aluminum alloy plates. Due to its excellent formability, lightweight, corrosion resistance, and thermal conductivity, it is commonly used in industries such as cookware, lighting, road signs, and automotive parts. Common aluminum disk alloy grades include 1050, 1060, 3003, and 5052, and tempers include O, H14, and H24. Its smooth surface and uniform thickness make it ideal for deep drawing, spinning, and surface treatments such as polishing, anodizing, or coating. Aluminum disk is a key raw material for the manufacture of frying pans, pressure cookers, lampshade reflectors, traffic signs, and other shaped aluminum products.
