5251 Aluminum Coil Introduction:

The 5251 aluminum coil is the form of the 5251 aluminum alloy through the coil. It is the same as the 5251 aluminum plate in terms of element content and mechanical properties. 5251 aluminum coil is a relatively hard aluminum coil in the 5 series aluminum alloy, containing about 2% magnesium and 0.3% manganese.

5251 Aluminum Coil Feature:

Ideal for welding methods such as gas welding, arc welding, contact spot welding and wire welding, with strong weldability

It can effectively resist corrosion from the atmosphere (including marine steam and industrial atmosphere), fresh water, sea water, neutral inorganic salt solutions, most acids and organic substances, and has strong corrosion resistance

Good machinability, ductility, formability, moderate static strength, high fatigue strength, high hardness and other mechanical properties

The thickness of the surface protective film can be increased by anodizing process, thereby improving its corrosion resistance

5251 Aluminum Coil Applications:

Lighting, wall and ceiling decoration, solar water heaters;

Nameplate, luggage, frame;

Home audio, refrigerator, TV, microwave oven;

Sheet metal, pipe insulation, automobile decoration, ship plate protection, traffic signs;

Ships, marine structures, boats, vehicles, containers;

Pressure vessels, heat transfer devices, welded structures, metalwork, paneling and pressing, silos or boiler fabrication;





Shipping and Packing Information:

1. Cover the fumigation chapter.
2. Place 20 packs of desiccant per carton.
3. Galvanized steel strip, coated cardboard package to prevent rust.
4. Pine wood bottom bracket is supported by glued bottom plate to maintain the flatness of the aluminum plate.
