Aluminium sheets are divided into cold-rolled and hot-rolled, as well as thin sheets and medium-thick sheets. Aluminium sheets have high plasticity, corrosion resistance, conductivity, and thermal conductivity, but low strength, cannot be strengthened by heat treatment, and have poor machinability. They can be gas welded, hydrogen atomic welded, and contact welded, but are not easily soldered. They can withstand various pressure processing, drawing, and bending.
Common aluminium sheet materials and their characteristics
1. Pure aluminium sheet: Made mainly of pure aluminium, it has good corrosion resistance, thermal conductivity, and electrical conductivity. It is lightweight, easy to process, and widely used in aviation, electronics, construction, and other fields.
2. Aluminium alloy sheet: Aluminium alloy sheet is made by alloying aluminium with other metal elements. Common aluminium alloy sheet materials include aluminium-manganese alloy sheet, aluminium-magnesium alloy sheet, aluminium-silicon alloy sheet, etc. Aluminium alloy sheets have high strength, corrosion resistance, and heat treatment performance, and can be used in the manufacturing of automobiles, aerospace, ships, and other fields.
3. Coated aluminium sheet: The surface of aluminium sheet can be coated with different coating materials to increase its weather resistance, corrosion resistance, and decorative properties. Common coating materials include fluorocarbon coating, polyester coating, oxide coating, etc. Coated aluminium sheets are suitable for architectural curtain walls, ceilings, billboards, etc.
4. Titanium alloy sheet: Made of titanium and its alloys, it has the advantages of low density, high strength, high temperature resistance, and corrosion resistance, and is widely used in aerospace, chemical, medical, and other fields.
5. Aluminium plastic sheet: Aluminium plastic sheet consists of a pure aluminium outer layer and a plastic composite layer. It has the rigidity and corrosion resistance of aluminium sheet, as well as the lightness and formability of plastic, and is widely used in billboards, signs, and interior decoration.
In general, there are many types of aluminium sheet materials, each with unique characteristics and applications. From pure aluminium sheet to aluminium alloy sheet, and then to aluminium plastic sheet and titanium alloy sheet, they all play important roles in different fields. With the continuous development and innovation of technology, the diversification of aluminium sheet materials will better meet the needs of various industries.
