Henan Gnee New Material Co., Ltd. is one of the most reliable manufacturers and suppliers of 6061 marine aluminum sheet in China. With abundant experience, we warmly welcome you to wholesale high quality 6061 marine aluminum sheet in stock here from our factory. Good service and reasonable price are available.
6061 Aluminum Sheet is an alloy made of silicon and magnesium. It is an easily machined, weldable and formable aluminum grade.
In terms of corrosion resistance, 6061 Aluminum Alloy Sheet is the highest among similar heat treated aluminum grades. This allows it to be used in heavy structures and marine environments. The product has a protective surface film that helps prevent corrosion.
For further corrosion resistance, other coatings can be applied or it can be anodized.
It has a good weight-to-strength ratio, making it ideal for heavy structures.
The product is highly weldable and can be welded using any welding method. It can be annealed, which will put it in a state that is easy to cold work.
GNEE can provide a number of processing services for deep processing methods such as stamping, drilling, bending, deep drawing, tapping and cutting, CNC, etc.
When annealing this 6061 aluminum alloy, it is recommended to place it in 775 degrees Fahrenheit for two to three hours, and then steadily drop 50 degrees every hour until it drops to 500 degrees Fahrenheit. Other heat treatment methods that can be used include solution heat treatment, aging precipitation, heat treatment, and hot working.
Other applications for 6061 aluminum grades include marine fittings, marine components, fasteners, truck parts, hinge pins, magneto parts, frames, and structural components.

our advantages
GNEE is one of the best marine grade aluminum plate manufacturers and exporters in China, certified by multiple classification societies.
GNEE's aluminum products are widely used in ship decks, sides, bottoms, hulls, decks, keels, chimneys and other parts. It can be used to manufacture a variety of ships from small yachts to tens of tons of cruise ships.
The world's most advanced equipment 3000T stretching machine is introduced, which can be used to perform permanent tensile plastic deformation of 1.0%-3.0% on the plate within the specified time according to the process requirements. By transitioning from elastic deformation to plastic deformation, the residual internal stress after quenching is eliminated, ensuring that the product will not deform during processing.
GNEE adopts advanced production technology to reduce the tendency of ingot cracking and improve the surface quality of rolled plates.
GNEE can provide value-added services such as anodizing, chemical milling, deep hole drilling, grinding, perforation, polishing, rigidity, and ring drilling for your deep processing marine grade aluminum plate.
