Why is al alloy 5052 the most commonly used?
5052 aluminum plate is an AL-Mg series alloy aluminum plate, in which magnesium is the main alloying element of 5052 alloy aluminum plate. It is the most widely used anti-rust aluminum, which has high strength, especially anti-fatigue strength. It has high plasticity and corrosion resistance, cannot be strengthened by heat treatment, and has good plasticity during semi-cold work hardening, but low plasticity during cold work hardening. It has good corrosion resistance, good weldability, poor machinability, and can be polished.
5052 has magnesium as its main alloying element and has good formability, corrosion resistance, and weldability, with moderate strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles, ships, instruments, street lamp brackets, rivets, hardware products, and electrical appliance casings.
AL-Mn series alloy is the most widely used anti-rust aluminum, which has high strength, especially anti-fatigue strength. It has high plasticity and corrosion resistance, cannot be strengthened by heat treatment, and has good plasticity during semi-cold work hardening, but low plasticity during cold work hardening. It has good corrosion resistance, good weldability, poor machinability, and can be polished. It is mainly used for parts with high plasticity and good weldability that work in liquid or gas media under low loads, such as fuel tanks, gasoline or lubrication pipelines, various liquid containers, and other small load parts made by deep drawing: wire for making rivets.
The main applications of 5052 aluminum plate are for parts requiring high plasticity and good weldability. It is also commonly used in sheet metal parts for transportation vehicles and ships, instruments, street lamp brackets and rivets, hardware products, and electrical appliance casings. It can also be used to manufacture aircraft fuel tanks, oil pipes, and aerospace aluminum alloy materials. It is a typical anti-rust alloy material.
The composition of the aluminum alloy is as follows:
aluminum (Al) as the main component with a balance;
silicon (Si) at 0.25%;
copper (Cu) at 0.10%;
magnesium (Mg) at 2.2-2.8%;
zinc (Zn) at 0.10%;
manganese (Mn) at 0.10%;
chromium (Cr) at 0.15-0.35%;
iron (Fe) at 0.40%.
The tensile strength (σb) ranges from 170 to 305 MPa.
The conditional yield strength σ0.2 (MPa) is ≥65.
The elastic modulus (E) is 69.3-70.7 GPa.
The annealing temperature is 345°C.
The thickness of the aluminum plate ranges from 0.15 mm to 50 mm, with a width of 100 mm to 2000 mm and a length of 1000 mm to 9000 mm. The thickness of the aluminum coil ranges from 0.05 mm to 15 mm, with a width of 15 mm to 2000 mm.
5052 aluminum sheet is a representative aluminum sheet of the 5 series. 5052 is an Al-Mg series rust-resistant aluminum alloy that cannot be heat-treated for strengthening. Its chemical composition is similar to that of the 5A02 alloy, and its properties are basically the same as those of 5A02. The alloy has high plasticity and low strength, and good corrosion resistance and welding properties. However, the cutting performance of the alloy is poor in the annealed state.
Advantages of 5052 marine aluminum sheet:
- Good corrosion resistance, reducing maintenance costs such as oiling, and long service life;
- Good processing performance, easy to cut, stamp, bend, form and cut in various forms, suitable for streamlined ship structures; can extrude large wide thin-walled profiles, reducing the number of welds and rationalizing and lightening the ship structure;
- Good welding performance, easier to weld;
- Small elastic modulus, high ability to absorb impact stress, and large deformation capacity;
- Aluminum waste is easy to recycle and can be reused.
5052 aluminum sheet is mainly used for high plasticity and good welding properties, such as sheet metal parts for transportation vehicles, ships, instruments, street lamp brackets, rivets, hardware products, and electrical enclosures. As a typical rust-resistant aluminum sheet, it is also commonly used in ship operation consoles.
