Main characteristics of aluminum alloy materials

• 1. Lightweight and high strength: The density of aluminum alloy is about 2.7g/cm³, which is much lower than iron and steel (about 7.8g/cm³). Echter, through reasonable alloying design, its strength can reach or even exceed that of some high-quality steels. kind. Bijvoorbeeld, the tensile strength of aviation-grade 7075 aluminum alloy materials can reach more than 570MPa.
• 2. Sterke corrosieweerstand: A dense oxide film is easy to form on the aluminum surface, which effectively prevents the internal metal from contacting the air, thus having good corrosion resistance. In aanvulling, some aluminum alloys, zoals 6061, 5083 and other marine-grade aluminum alloys, show excellent corrosion resistance in seawater environments.
• 3. Good electrical and thermal conductivity: The electrical conductivity and thermal conductivity of aluminum alloy are second only to silver and copper, which have significant advantages for power transmission equipment, radiatoren, enz. The electrical conductivity of pure aluminum is 377W/(m·K), while some aluminum alloys such as 1050 aluminum alloy can still maintain high electrical conductivity.
• 4. Ease of processing: Aluminum alloy materials has good castability, forging and weldability, and is easy to undergo various forms of mechanical processing and heat treatment to meet the design needs of different structural parts and parts.

Applicationss of aluminum alloy

1050 aluminium profiel: This is a kind of industrial pure aluminum with high purity. Its aluminum content is usually more than 99.5%, and it has good electrical conductivity and corrosion resistance. It is mainly used in manufacturing applications that do not require high strength but require high electrical or thermal conductivity, such as shielding layers of power cables, electronic foils, and aluminum foil for food packaging. 1050 aluminum alloy can be made into sheets or foils of different thicknesses and maintains good formability after O-state (fully annealed) treatment.

3003 aluminium profiel: This series of aluminum alloy materials contains a small amount of manganese, which gives it good mechanical properties and corrosion resistance. It is a commonly used anti-rust aluminum alloy. It is suitable for making tanks, car radiators, household kitchenware and other parts that require both lightweight and corrosion resistance. 3003 aluminium plaat can be cold rolled into plates of different thicknesses or extruded into profiles of various cross-sectional shapes. The status codes include H14 (semi-hard), H16 (medium hardness), H18 (fully soft), enz., and different tempering states Corresponding to different molding and use requirements.

5052 aluminium profiel: This alloy contains magnesium and is a typical rust-proof aluminum alloy with high strength and excellent weldability. It is suitable for use in high-strength corrosion-resistant fields such as ships, voertuigen, and containers, as well as complex structural parts such as pressure vessels and aerospace components. 5052 aluminum alloy materials is often processed into thick or medium-thick plates. The states include H32 (solid solution + slight incomplete annealing), H34 (further annealing to increase toughness) and H38 (higher degree of annealing to improve ductility), depending on the final product. Select the corresponding state according to the mechanical performance requirements.

6061 aluminium profiel: Belongs to the 6xxx series. It mainly adds silicon and magnesium. It can be strengthened after heat treatment, so it has high mechanical strength and good corrosion resistance. It is widely used in building structures, bruggen, bicycle frames, aerospace parts and other fields. 6061 aluminium profiel products can be in T6 state (solid solution + artificial aging treatment). In this state, the material reaches the best balance of mechanical properties. Its size specifications can be customized according to design requirements, and can be produced from thin plates to thick-walled pipes.

7075 aluminium profiel: This ultra-high-strength aluminum alloy contains zinc and magnesium and is known as an “aerospace-grade” aluminum alloy with extremely high strength and hardness. It is mainly used in aircraft structural parts, high-end sports equipment, precision mechanical parts and other application scenarios that require extremely high strength to weight ratio. 7075 aluminum alloy materials is generally processed through T6 or T73/T76 conditions to obtain the best mechanical properties.
