5a83 ultra-precision aluminum plate sheet is a flat ingot made by mold water pouring casting process as raw material. The grain size of raw material is the same as that of rolled aluminum plate, and the control of hydrogen (H) and impurity content of 5083 raw material is more strict. 5083 is formed by sawing, which has less internal stress, better grain roundness and better product isotropy.

According to the production characteristics of 5a83 ultra-precision aluminum plate sheet, the casting internal stress is eliminated after homogenization annealing. In the production process of aluminum plate, there is no processing deformation and processing stress, so this processing method can ensure that the aluminum plate will not be deformed in the subsequent processing of parts.

Characteristics of 5a83 ultra-precision aluminum plate sheet 

• 1. Stress relief state, small processing deformation, good formability and weldability.
• 2. The product is easy to process and has good surface treatment effect.
• 3. High strength, good corrosion resistance and oxidation resistance.
• 4. The product is isotropic and has high dimensional stability.
• 5. Surface finish milling can be carried out as required, with good surface quality, and the finished product can be coated on both sides.
• 6. Excellent high temperature resistance.
• 7. The internal and external properties of ultra thick plate are consistent.

The strict control of impurities, alkali metal elements and low melting point elements of the 5083 ultra-precision aluminum plate sheet improves the corrosion resistance and creep resistance of the alloy. The two sides of the plate are milled and milled to present an ultra-flat and fine surface. The dimensional tolerance standards are world-leading, and the factory is fully Inspection, double-sided film protection, high thickness specification coverage (≥4. 5mm), 5083 ultra-precision aluminum plate sheet is improved on the basis of European standard DIN EN 573--3/3. 3547, to meet the requirements of food-grade materials, Widely used in fixtures, jigs, IT, semi-Conductors, Medical, Electronic Instruments, Optical and Communication Carriers and Platforms, Precision Mechanics, Reference Plates, Panels, Engine Manufacturing and Fixture Manufacturing, Vehicle Engineering, Shipbuilding, Aviation Fixtures, Bicycle Parts, Valve Bodies, Tube Formwork, Cutlery Moulds, Food Grade Packaging, Blow/Blister Moulds, Templates, Marine Operation Components, General Tools and more.
Due to the addition of trace amounts of rare earth elements and B and C, the thermal conductivity, heat dissipation, high temperature and corrosion resistance are improved; the dimensional accuracy and processing stability of the plate are at the international advanced level.
