What are the differences between aluminum coils and aluminum plates?

What are the differences between aluminum coils and aluminum plates?

Aluminum plates and aluminum strips are easier to understand. One is a plate and the other is a coil.

Cold-rolled aluminum plates do not have as good a surface as hot-rolled aluminum plates, which are suitable for oxidation.

The manufacturing processes of aluminum coils and aluminum plates are different

Aluminum strip (Aluminum strip/Aluminum strip) is in the shape of a roll. Cast-rolled aluminum coils and hot-rolled aluminum coils are made of pure aluminum or aluminum alloy, and are rolled into thin aluminum coils of different thicknesses and widths by a cold rolling mill. After bending and bending, they are slit longitudinally into aluminum coils of different widths by a slitting machine. Reel tape.

Aluminum sheet plate is a rectangular plate. Cast cast-rolled aluminum coils are cut into cast-rolled aluminum plates (CC materials), or cast aluminum flat ingots are used to roll and processed into rectangular plates (DC materials). They are divided into non-heat-treatable aluminum plates and heat-treatable aluminum alloy aluminum plates. , thin aluminum plates, medium-thick aluminum plates, patterned aluminum plates, etc.

What are the differences between cast-rolled and hot-rolled aluminum coils?

(1) The production process is different: cast-rolled aluminum coils are processed by a casting machine into cast coils (8mm thickness) and processed by a cold rolling machine, while hot-rolled aluminum coils are made from aluminum plate ingots (400-500mm thickness) Heated, rolled by a hot rolling mill at high temperatures;

(2) Different supply of raw materials: The difference between the two lies in the supply of billets. The hot-rolled billets are cast aluminum ingots - heated - rolled into coils for cold rolling, while the cast-rolled billets are cast-rolled coils - cast-rolled;

(3) Different thicknesses: The maximum thickness of cast-rolled aluminum coils is 7mm, and the hot-rolled aluminum coils can be 600mm thick and <7mm. They can usually be made into aluminum coils or aluminum plates.

(4) Different properties: hot-rolled aluminum plates have good surface quality, strong mechanical properties and ductility, and good oxidation effects. For example, aluminum discs are generally processed from aluminum plates, and are naturally affected by the properties of the aluminum plates;

(5) Different uses: Cast-rolled aluminum coils are mostly used in molds, while hot-rolled aluminum coils are suitable for stamping and stretching.

(6) Different prices: The process of cast-rolled aluminum coils is simple and the price is cheaper than hot-rolled aluminum coils.

(7) Different finished products: Usually the elongation of cast-rolled products is lower than that of hot-rolled products.

Aluminum plates and aluminum coils are packaged in different ways

Aluminum coils and sheets are widely used in various industries, and packaging and transportation are very important.

Usually, fumigation is done on tic-tac-toe wooden pallets or wooden boxes. The outside is fixed with steel strips, the outside of the aluminum coil is covered with double-layer moisture-proof tarpaulin, and the inside is protected from moisture-proof agent. It is packaged in a sealed manner and is suitable for long-distance transportation and sea transportation.

Aluminum coil packaging method

Vertical packaging: The inner diameter of the aluminum coil is facing upward and placed on the fumigation wooden pallet to save space and freight costs. The aluminum processing factory is required to have an aluminum coil vertical turning machine. The width of the aluminum coil is less than 1100mm, which is suitable for vertical packaging.

Horizontal packaging: Aluminum coils are laid horizontally and placed on fumigated wooden pallets. This takes up more space for transportation and is safer for shipment. Horizontal packaging is recommended for aluminum coils with a width exceeding 1250mm. .

Weight: 1-2 tons/pallet
