7075 aluminum plate is a high-strength aluminum alloy plate, usually composed of aluminum, zinc, magnesium, copper and other elements. The specifications of 7075 aluminum plate usually include parameters such as plate thickness, width and length. Common specifications include thickness of 1mm-200mm, width of 500mm-2600mm, length of 1000mm-12000mm, etc. 7075 aluminum plate can usually undergo different heat treatment processes to obtain different states. Common states include T6 state, T651 state, O state, etc.
7075 aluminum plate suppliers are specialized in producing high quality aluminum plate and the general process of producing 7075 aluminum plate includes the following steps:
- Raw material preparation: Select high-purity aluminum, zinc, magnesium, copper and other raw materials, mix them in a certain proportion to prepare alloy raw materials.
- Melting: Put the alloy raw materials into the melting furnace for melting, and control the alloy composition and temperature.
- Casting: Pour the molten alloy liquid into the aluminum plate mold, and obtain the aluminum plate blank by shaping and cooling.
- Rough rolling: The aluminum sheet billet is initially rolled through a rolling mill to form the required sheet thickness.
- Finishing rolling: The aluminum sheet billet after initial rolling is finished to further adjust the size and surface quality of the sheet.
- Annealing: Annealing the 7075 aluminum plateto eliminate stress and improve the hardness and strength of the sheet.
- Surface treatment: Surface treatment of the 7075 aluminum plate, such as anodizing, sandblasting, etc., is performed to increase the corrosion resistance and aesthetics of the surface.
7075 aluminum plate is commonly used in aerospace, military, shipbuilding, automobile, sports equipment and other fields, and has the following main uses:
- Aerospace field: used to manufacture aircraft structural parts, aircraft engine parts, etc.
- Military field: used to manufacture military equipment, rocket engine parts, etc.
- Automobile field: used to manufacture automobile parts, such as body structure, wheels, etc.
- Sports equipment field: used to manufacture bicycle frames, trekking poles and other equipment with high strength requirements.
