The 1000 aluminum alloys have a high aluminum content of more than 99.00%. It has good electrical conductivity, good corrosion resistance and good welding performance, but has low strength and cannot be strengthened by heat treatment. The 2 series is an aluminum-containing alloy with copper as the main element, and has serious intergranular corrosion tendency.
3000 series aluminum alloys with manganese as the main alloying element cannot be strengthened by heat treatment. They have good corrosion resistance, good welding performance and plasticity, and low strength. However, the strength can be enhanced through cold work hardening. Coarse grains are easily produced during annealing. 5000 aluminum alloys have good durability, good welding performance and good fatigue strength. It cannot be strengthened by heat treatment and can only be strengthened by cold working.
The 6xxx aluminum alloys mainly contain two elements: magnesium and silicon. So they combines the advantages of the 4000 series and the 5000 series. Among them, 6063, 6061, and 6005 are the most used.
The magnesium content of 6005 is 0.4%~0.6%, and the silicon content is 0.6%~0.9%. The magnesium content of 6061 is 0.8%~1.2%, and the silicon content is 0.4%~0.8%. The magnesium content of 6063 is 0.45%~0.9%, and the silicon content is 0.2%~0.6%..
Alloy 6063 has excellent features such as processing performance, excellent welding characteristics and electroplating properties, good corrosion resistance, high toughness,etc. Alloy 6063 t6 is a common temper.
6061 aircraft aluminum is a cold-processed aluminum forged product suitable for applications requiring high corrosion resistance and oxidation resistance. It has good workability, excellent interface characteristics, easy coating, and good processability, which can be used on low voltage weapons and aircraft joints.
The plasticity properties of 6063 aluminum are better than 6061, so most extruded profiles are made of 6063. However, the strength and processing performance of 6063 are not as good as 6061 aluminum. Compared with 6061 and 6063, 6005 aluminum has higher tensile strength and yield strength, and has better fracture toughness. For profiles requiring higher strength, 6005 will be used.
The surface gloss of 6063 and 6061 is better than that of 6005, and 6005 aluminum will be darker. Therefore, 6063 aluminum is more suitable as a decorative material. 6061 and 6005 aluminum alloys can also be made into aluminum plates, while 6063 basically cannot be made into aluminum plates.
6063 aluminum alloy is an aluminum alloy material with extremely strong comprehensive properties and is widely used in industry and construction. 6061 aluminum is mainly used in aerospace, ship equipment, molds, electronic products, anti-corrosion structures and other fields. 6005 aluminum alloy is often used in structures that require high strength, such as ladders and TV antennas.
