Analysis of common problems of 5052 aluminum plates

The most common use of the 5052 aluminum plates is the appearance or electronic parts. The common problems of 5052 aluminum plates are as follows:


There are defects on the surface of the aluminum sheet.

The surface problem of 5052 aluminum plates, except for the case and billet, is derived from the production process of each machine.

2. After oxidation, color difference, black silk, sand hole and other defects.

Black silk can be caused by many reasons, such as the accessory machine drops of the mill on the oil due to poor management, such as stress or too much tension on the surface of indentation, if again to the thin material of rolling, the dark mark will become more and more to the more thin, dark lines or black line, and sometimes even can't distinguish oil or mark, even can't see what's the color on the surface, but were very obvious after oxidation, for the customer, see inconsistent phenomenon appearance, affirmation is to refuse. After oxidation, black silk is the most effective. Once this happens, there is almost no room for survival, and the loss and consequences are irreparable. Second off color, generally do look more products, also cannot appear off color, any customer is unwilling to accept a similar "two leatherface" products, in order to eliminate these problems, or want to rely on the source machine to control.

The reasons of sand hole, sand hole is commonly internal structure problem, because when slab ingot impurities or didn't rule out clean water, or other elements not mix factors such as, so request in ingot casting the source link to control testing.

3. Performance requirements: tensile strength, hardness, elongation, bending requirements, etc.

As for performance problems, the most is the bending deformation, this link because the customer product use different, cannot treat as the same, but in general the annealing at this stage, how many temperature, how long, how thick to retreat, there is a standard.

5052 aluminum plate has wide USES, the product is classified, but as long as pay attention to each link of the controls, to the common problem in source control, process stability, make sure to attract market products!
