Aluminium anodized sheets
Electrochemical surface treatment, also known as anodizing, is a process of increasing the natural oxide layer formed on the aluminum surface when exposed to oxygen.
The oxide layer is increased using electric current, which makes the aluminum surface more durable. Anodizing can also be used for decorative purposes, as the anodized surface can be colored. Aesthetically, anodizing preserves the metallic surface of aluminum and makes it more uniform.
The anodizing layer is measured in microns (µm):
10 µm: Suitable for indoor use.
15 µm: Most common, good durability in both indoor and outdoor conditions – in dry and clean air.
20 µm: Normal to strong durability outdoors, e.g. in transportation and construction. Suitable for use in chemically affected indoor environments, e.g. food industry.
25 μm: The surface withstands corrosive environments and high wear loads.

Aluminum (aluminum) – non ferrous metal, lightweight, malleable and with silver-gray color
Aluminum properties
- Its content is 8% of the earth’s crust
- Its density is 2.699 g/cm3
- Its melting point is of 660oC
Other properties
- Resistance to corrosion due to aluminum oxide Al2O3, which coincides intrinsically
- Very high electrical and thermal conductivity
- Naturally found aluminum compounds (mostly with silicon and oxygen)
Application
Pure form of aluminum (content of Al – 99%) used for production of electrical wires, foils, cable coating, chemical equipment, capacitor foil, equipment for the food industry as well as in electronics and electrical engineering and plating process.
Aluminum alloys (attained by adding Si, Mg, Mn, Cu, Zn, Ti, Ni, Fe) used as structural materials in the construction industry (including roofing), automotive industry, aerospace industry, marine industry, rail industry, air-conditioning and ventilation industry, power industry, refrigeration industry, for heating elements (collectors, heat exchangers), as decorative elements in furniture and advertising industry as well as for manufacture of electrical wires.
