Aluminum leaf orange peel, Dnipropetrovsk region.

"
At present, aluminum sheet is the most practical type of colored rolled sheet, which is used in machine building, aircraft and shipbuilding, and other industries. The cost of the ego is low, because raw materials are found in abundance in natural deposits, this is one of the cheapest metals. Such a sheet is very strong, light, flexible, durable and plastic. It is perfectly amenable to cold processing, which is why products of any configuration can be obtained from it. It has a good thermostatic effect, is resistant to chemical reagents and is non-magnetic. It is resistant to corrosion, biologically inert, meets the strictest sanitary standards, which allows it to be used in any field of activity. This material has an aesthetic appearance, is easy to paint, retains its color for a long time, and does not require time-consuming care.
Aluminum sheet is a rolled product made from aluminum alloys. It is most in demand in mechanical engineering, aircraft engineering, and shipbuilding. Aluminum sheet, in the production process it undergoes the following processing stages:
- cold deformation (rolling/drawing);(//tractor-service.com)
- hot deformation.
Aluminum is a plastic material that is easily cold-formed, resulting in parts of the desired shape.
The aluminum sheet is made of aluminum alloys according to the standards of GOST 21631. It must not have visible defects on the surface, for example, cracks, bubbles, corrosion spots, tears.
Also, burn marks are not allowed on aluminum sheets - the surface must be glossy or matte."
