marine grade aluminium sheets in Indonesia

Comprehensive knowledge of marine grade aluminium sheets in Indonesia

Marine grade aluminium sheets in Indonesia are made of aluminum materials with different cross-sectional shapes through hot melting and extrusion. The production process mainly includes three processes: casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, etc.). Aluminum profiles are classified according to their uses: 1. Industrial aluminum: mainly used in airplanes, trains, industrial radiators, automobiles, and electrical appliances.

Aluminum alloy building materials: marine grade aluminium sheets in Indonesia are mainly used for building doors and windows, curtain walls, indoor and outdoor decoration and building structures.

The surface treatment of surface treatment marine grade aluminium sheets in Indonesia

According to the surface treatment, marine grade aluminium sheets in Indonesia are divided into: 1. Anodized aluminum materials: the surface of the profiles is anodized, electrolytic colored or organic colored. 2. Electrophoretic painted aluminum: the surface of the profile is treated by anodizing and electrophoretic coating. 3. Powder sprayed aluminum: marine grade aluminium sheets in Indonesia are coated with thermosetting organic polymer powder. 4. Fluorocarbon paint sprayed aluminum: the surface is coated with polyvinylidene fluoride paint. At present, the commonly used heat-insulating aluminum material is a kind of Marine aluminum plate that adopts a strip type or a cast type composite.

The film thickness of anodized aluminum is divided into AA10, AA15, AA20, AA25, and the film thickness of electrophoretic painted aluminum is divided into A. B. S. The minimum local thickness of the coating on the decorative surface of powder sprayed aluminum is <40um. The thickness of the paint layer on the decorative surface of the fluorocarbon paint sprayed aluminum is different depending on the type of coating. The average thickness of the second coating is <30um, and the third coating Average film thickness <0um, average film thickness of four coatings <65um.

The chemical composition, mechanical properties and technical parameters of different grades and supply status are different. Customers should check one by one against the standard (contract). It is recommended to fully consider the impact of color and chromatic aberration on the building structure when selecting alloy grades and supply status. Salt spray corrosion resistance, abrasiveness, weatherability, mortar property, etc.: This is an important technical parameter of aluminum alloy, reflecting the properties of aluminum alloy.
