1060 aluminum sheet, as a core representative of the 1 Series pure aluminum, has an aluminum purity of over 99.6% and is the most basic general-purpose aluminum sheet on the market. Its greatest advantages are high plasticity, ease of cutting and bending, and excellent weldability. It also offers outstanding electrical and thermal conductivity, with an electrical conductivity of up to 60% IACS, all at a low cost with exceptional cost-performance. However, 1060 aluminum sheet has low hardness, relatively low strength, and poor wear resistance. Without alloy strengthening, it cannot withstand pressure-bearing or deformation-resistant conditions. It is currently mainly used in low-load, non-structural applications such as general electrical heat-conducting components, decorative panels, insulation enclosures, and simple sheet metal fabrication, making it the primary category of civil-use basic aluminum material.

3003 aluminum sheet belongs to the 3 Series aluminum-manganese alloy rust-proof aluminum sheet. The addition of manganese to pure aluminum thoroughly addresses the shortcomings of low strength and susceptibility to deformation found in pure aluminum sheets, while retaining excellent formability and weldability. This material offers corrosion resistance and anti-rust performance far superior to the 1 Series pure aluminum, with low processing difficulty and minimal cracking risk. It does not require heat treatment for strengthening and can achieve structural stability through cold working alone. Compared to other alloy aluminum sheets, 3003 offers a balanced cost-performance ratio and is primarily used in lightweight anti-rust applications. It is widely used in HVAC ducts, roofing waterproof panels, fuel and water tanks, light-duty outdoor decorations, and hardware stamping parts, making it the universal first choice for mid-range anti-rust sheets.

5052 aluminum sheet is a 5 Series aluminum-magnesium alloy sheet and is widely recognized in the industry as the "versatile rust-proof aluminum sheet," offering comprehensive performance superior to 3003. Through magnesium alloy strengthening, it delivers significantly improved tensile strength, hardness, and fatigue resistance, combined with exceptional resistance to seawater, salt spray, and humid corrosion. It offers stable bending and forming performance with minimal cracking during deep processing, and is suitable for medium- to high-pressure load-bearing conditions. By comparison, 1060 is more suited for basic decorative use, 3003 for light-duty anti-rust applications, while 5052 is positioned for high strength, high corrosion resistance, and high toughness. It is mainly used in demanding scenarios such as marine sheets, new energy battery enclosures, truck bed flooring, pressure vessels, outdoor heavy-duty sheet metal, and marine engineering components, making it the core material for industrial anti-rust structural aluminum sheets.

6061 aluminum sheet, as a representative of the 6 Series aluminum-magnesium-silicon alloy, is the only general-purpose structural aluminum sheet that can be strengthened through T6/T5 heat treatment. It can truly be called the "all-rounder" among aluminum sheets. Through the formation of strengthening phases by magnesium and silicon, it achieves comprehensive upgrades in strength, hardness, toughness, and deformation resistance, while also offering excellent weldability, machinability, and anodizing results, with outstanding dimensional stability. Compared to 3003 and 5052, which cannot be strengthened by heat treatment, 6061 can be tailored through process control to suit high-precision structural applications, addressing the structural strength limitations of rust-proof aluminum sheets. However, its corrosion resistance is slightly lower than that of the 5 Series, and its cost is relatively higher. It is primarily used in high-precision, high-load structural applications such as machinery structural plates, precision tooling plates, mold backing plates, high-end curtain wall structural components, and transportation equipment load-bearing sheets.

Industry analysts summarize that the four mainstream aluminum sheets form a clear material selection gradient: 1060 pure aluminum sheet focuses on low cost and high thermal conductivity, suitable for basic decorative and electrical applications; 3003 aluminum sheet focuses on light-duty anti-rust and high cost-performance, suitable for general light industrial anti-corrosion applications; 5052 aluminum sheet focuses on high-strength anti-corrosion and weather-resistant pressure-bearing, suitable for outdoor, marine, and new energy heavy-load applications; and 6061 aluminum sheet focuses on high precision and high strength, suitable for industrial precision load-bearing and high-end equipment applications. As lightweight and refinement upgrades accelerate across industries, precise matching of aluminum sheet materials and customized processing on demand will become the mainstream development trend in the aluminum application industry, continuously driving the high-quality development of the domestic aluminum materials sector.
