Features of Aluminum Coil
1. Good temperature resistance
The melting point of aluminum is 660 degrees, and the general temperature does not reach its melting point.
2. Excellent Corrosion resistance
Because of its tight surface oxide film, it has strong adhesion, oxidation resistance, acid resistance, alkali resistance, corrosion resistance, decay resistance, and UV resistance.
3. Color uniform, long-lasting, even, and delicate
Soft and colorful, avoiding the individual chromatic aberration of traditional spraying, no matter how large the ceiling, its color, and color are consistent, lasting, and new.
4. Rigid joint, extremely high strength of the board
Rigid and tough combination, free to cut, slit, arc, balance, drilling, joint fixation, and edge compression molding.
5. Environmental protection
Not easy to turn yellow, using chromium-free treatment liquid to make up for the defects of easy discoloration of the laminating board; the roller paint contains active chemical molecules, which promote the formation of a protective layer on the surface of the material. Active chemical molecules are stable and easy to recycle, meeting environmental requirements.

How To Choose Aluminum Coils?
When we choose an aluminum coil, it is important to note that choosing the right alloy for the aluminum coil is directly dependent on the properties and the specific using scenario. Before you purchase aluminum coil, it is vital to pay attention to the flowing properties:
- Tensile Strength
- Thermal conductivity
- Weldability
- Formability
- Corrosion Resistance
Surface Coating For Aluminum Coil
1. Fluorocarbon-coated color-coated aluminum coil (PVDF)
The fluorocarbon coating is a coating of PVDF resin mainly referring to a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other small amounts of the fluorine-containing vinyl monomer. A fluorine/carbon bond combines the chemical structure of the fluoric acid base. This chemical structural stability and firmness make the physical properties of fluorocarbon coatings different from conventional coatings. In addition to the abrasion resistance in terms of mechanical properties, impact resistance has excellent performance, especially in harsh weather and environment, showing long-lasting resistance to fading and UV. After the high-temperature barbecue is formed into a film, the molecular structure in the coating is tight and has excellent weather resistance. It is especially suitable for the decoration and display of indoor, and outdoor decorations, commercial chains, exhibition advertisements, etc.
2. Polyester coated aluminum coil (PE)
The polyester coating formed by multiple baking of the surface of the aluminum plate can create a solid film adhered to have a protective decorative property. It is an anti-UV ultraviolet coating. The polyester resin uses a polymer containing an ester bond in the main chain as a monomer, and an alkyd resin is added. The ultraviolet absorber can be divided into a matt and a high-gloss series according to the gloss. It can give rich color to color aluminum products, has good shine and smoothness, as well as superior texture and hand feeling, and can also add layering and three-dimensionality. It can protect objects from ultraviolet radiation, wind, rain, frost, and snow; the coating can protect due to temperature differences, freeze-thaw cycles, corrosive gases, and microorganisms. Especially suitable for interior decoration and advertising panels.
