5083 aluminum plate is widely used in marine grade 4 x 8 aluminum sheet, the following is the production situation of aluminum manufacturers.

Different shapes and product forms are available such as angles, rods, seamless tubes, tubes, rods, sheets, plates, extrusions and fittings. Marine grade aluminum is a strain hardening and thermally conductive alloy that provides machinability, formability, weldability and corrosion resistance. Alloys are used in shipbuilding, oil and gas platforms, support structures, naval and commercial marine product applications. Custom lengths and anodized or powder coated can be specially ordered. Packing service and same-day delivery are available on most orders. Meets ASTM standards.

5083 aluminum sheet and plate have excellent thermal conductivity and higher strength than 5052. It is very resistant to seawater and industrial chemicals, making it ideal for welding. 5083 maintains excellent strength after welding and is easy to process.

Aluminum coil is a rectangular cross-section plate or coil processed by smelting, ingot casting, various preparations before rolling, flat rolling, heat treatment and finishing.

1. Preparation before hot rolling, including ingot quality inspection, soaking, sawing, milling, aluminum cladding and heating. The use of high-quality steel ingots is the premise to ensure the quality of finished products. The production of ingots for modern aluminum alloy strips adopts semi-continuous ingot production. The ingot size is large and the internal dendrites are fine.

2. The cooling rate of semi-continuous casting is very high, the solid phase diffusion process is difficult, and it is easy to form a structure with uneven chemical composition inside the ingot, such as intragranular segregation, which reduces the plasticity. Therefore, some aluminum alloys, especially hard aluminum alloy ingots, need to be homogenized.

3. When there are defects such as segregation floating material, slag inclusion, scarring and cracks on the surface of the ingot, milling should be carried out (see the milling surface of the non-ferrous alloy ingot billet), which is an important factor to ensure the good surface quality of the finished product. The amount of milling depends on the depth of the defect, usually 4 ~ 10mm.

4. For the machine heat treatment of aluminum sheet and sheet, in addition to the hot rolled and chilled products, the aluminum alloy strip should be annealed or quenched once according to the requirements (see heat treatment of non-ferrous alloys).
