There are rich kinds of aluminum sheet types, including marine grade aluminum, pcb drilling board, anodized aluminum sheet, aluminum checker plate, aluminum reflector sheet, color coated aluminum sheet, automotive aluminum sheet, aircraft aluminum,etc.
The marine aluminum sheet mainly use 5000, 6000 and 7000 alloy. The aluminum alloys used in the hull structure mainly include 5083, 5086 and 5456. 6xxx aluminum alloys is easy to have intergranular corrosion in seawater, so they are mainly used for the superstructure of ships.7xxx aluminum has high strength, which is mainly used in the superstructure of ships.
When we choose the metal substrate for the PCB drilling board, in addition to the heat dissipation performance, the thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface state and cost of the metal substrate should also be considered. Generally speaking, considering the conditions of cost and technical performance, aluminum plate is an ideal choice. The optional aluminum plates are 6061, 5052, 1060 and so on.
The anodized aluminum sheet has strong decorative performance and moderate hardness. It can be easily bent and formed for continuous high-speed stamping, which is convenient for direct processing into products without complicated surface treatment, which greatly shortens the production cycle and reduces production costs. The surface hardness of the anodized aluminum plate is high, reaching the gem level, with good scratch resistance.
4X8 checker plate is in great demand. 4x8 is an international standard size, meaning 4 feet wide and 8 feet long. Therefore, 4×8 aluminum checker plates are commonly used in truck, cold storage floor, ships,etc. In addition, there are 0.9mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm and various other thicknesses to choose from.
The aluminum reflector sheet is widely used in lighting and lamp decoration, solar collector and reflective material, interior building decoration, exterior wall decoration, household appliance panel, electronic product shell, furniture kitchen, automobile interior and exterior decoration, signage, logo, luggage, jewelry box and other fields.
