3000 aluminum is the most widely used rust-proof aluminum. It uses manganese as the main alloying element with a content of about 1.0-1.5. It is slightly lighter and more expensive than 1 series. It cannot be strengthened by heat treatment, but has good plasticity after cold working and annealing. The popular 3000 aluminum alloys are 3003, 3004, 3005, 3104, 3105, etc. The common thicknesses are 0.15/0.17/0.2/0.5/0.8/1.0/1.5/1.6/2.0/2.5/3.0/4.0/5.0/6.0/8.0mm.
3 series aluminum alloys have good formability, weldability, and corrosion resistance. They are used for processing parts that require good formability, high corrosion resistance, and good weldability, or work that requires both these properties and higher strength than 1 series alloys such as storage equipment.
3xxx VS 5xxx aluminum
3 series aluminum alloy is aluminum-manganese alloy, manganese is the main synthetic metal. 5 series is aluminum-magnesium alloy, magnesium is the main synthetic metal. Strictly speaking, 5 series alloy also contains manganese, but less than magnesium.
As the two most widely used aluminum alloys, 3 series aluminum plates have better anti-rust performance, good formability, high corrosion resistance and high strength. In addition to the characteristics of 3 series aluminum plates, 5 series aluminum plates have higher strength, corrosion resistance, better heat dissipation and strong pressure resistance.
In practical applications, 3 series aluminum plates are mostly used in places that require anti-corrosion and anti-rust properties, such as pipe insulation and cold storage floor anti-slip construction; 5 series aluminum plates are more used in manufacturing industries, such as ships, automobiles, radiators, etc., with a wider range of uses and more commonly used grades.
Because the 5 series covers the 3 series in terms of alloy composition, the production process and equipment requirements are higher, so the 5xxx aluminum sheets’ performance is better than the 3 series and the application range is wider, which ultimately leads to higher costs than the 3 series.
3003 VS3004
The chemical composition of 3003 aluminum sheet is usually composed of 1.2% manganese, 0.12% copper and 98.6% aluminum. At room temperature, the tensile strength of 3003 aluminum alloy reaches about 140MPa, and the yield strength is about 115MPa.
3004 aluminum has higher strength than 3003 aluminum plate with excellent formability, good corrosion resistance, good weldability and poor machinability. AA3004 aluminum-magnesium-manganese alloy is generally recognized as a roof and exterior wall material with a design service life of more than 50 years due to its moderate structural strength, weather resistance, stain resistance, and easy bending and welding processing.
