Chalco 5083 Aluminum cast mold plate has finer and homogeneous grain structure, with special state of stress digestion. Which makes almost no deformation after high speed of machining and cutting. Aluminum rolled plate sheet has orientated structure with strip distribution of grain along the processing direction, which makes more or less deformation of the parts after machining.
Characteristics of Chalco 5083 aluminum cast mold plate

1. State of stress digstion, almost no deformation for machining. Excellent formability and weldability.
2. Easy to processing, good effect of surface treatment.
3. High strength, good corrosion resistance and oxidation resistance.
4. Isotropic homogeneity, higher dimension stability.
5. Anti-magnetic, anti-radiation.
6. Fine surface miling as requirement. Good surface quality, the finished product can be double side filmed.

Application of Chalco 5083 aluminum cast mold plate:

Chalco 5083 aluminum cast mold plate is improved in the European standard DIN EN 573-3/3.3547, to meet the requirements of food grade material, widely used in IT, semiconductor, medical, electronic instrument, optical communication and the carrier and platform, precision machinery, base board, panel, engine manufacturing and fixture manufacturing, vehicle engineering, shipbuilding, aviation fixed parts, bicycle parts, valve, pipe mold, tableware mold, food grade packaging, plastic mold, blow / template, marine operations components, general tools and so on. Due to the addition of a small amount of rare earth elements and B and C, the heat conduction, heat dissipation, high temperature and corrosion resistance are improved. The dimensional accuracy and processing stability of the plate are at the international advanced level.
