Classification and application of rust-proof aluminum sheets plates

Rust-proof aluminum sheets plates are mainly made of aluminum-manganese alloy (Al-Mn) or aluminum-magnesium alloy (Al-Mg), and are named for their good corrosion resistance. Rust-proof aluminum sheets plates can be divided into several types according to the magnesium content. This article will explore the classification of rust-proof aluminum sheets, representative alloys and their applications.

Low magnesium content aluminum alloy

◆Magnesium content: less than 0.5%

◆Representative alloys: mainly include pure aluminum alloys such as 1050 and 1060. Although they are not strictly rust-proof aluminum sheets, they can be used for mild corrosion protection in some cases.

• 1050 aluminum sheet: used in some occasions that require high corrosion resistance and formability but low strength requirements, such as packaging containers in the chemical industry.
• 1060 aluminum sheet: used for outdoor curtain walls, thermal insulation materials and decorative aluminum veneers with mild corrosion protection.

Medium magnesium content aluminum alloy

◆Magnesium content: 0.5% – 3.5%

◆Representative alloys: 3003, 3004, 3105, etc. These alloys use manganese as the main alloying element, have good rust resistance and weldability, and are often used to manufacture pressure vessels and building materials.

• 3003 aluminum plate: used as the shell of new energy vehicle power batteries, brazing core materials in automotive water cooling plates, and pipe insulation materials in the chemical industry.
• 3004 aluminum plate: used for chemical product production storage devices, beverage cans, building materials, etc.
• 3105 aluminum plate: used for beverage bottle caps, cosmetic bottle caps, roof and exterior wall decoration, etc.

High magnesium content aluminum alloy

◆Magnesium content: 3.5% – 5%

◆Representative alloys: 5005, 5052, 5083, 5086, etc. These alloys have excellent corrosion resistance and strength, and are suitable for use in marine environments and other harsh conditions.

• 5005 aluminum plate: can be used for high-end curtain walls and building decoration materials in the construction industry; used to make inspection tools, fixtures and body parts in automobile manufacturing.
• 5052 aluminum plate: commonly used in sheet metal parts of yachts and hulls, automobile fuel tanks and pressure vessels.
• 5083 aluminum plate is commonly used in ships, vehicle materials, automobile and aircraft panels, pressure vessels that require strict fire protection, etc.
• 5086 aluminum plate is particularly suitable for ships and marine engineering, and is often used to manufacture hull outer plates, decks and marine equipment.
