The 1-series aluminum coil is pure aluminum, and its aluminum content reaches more than 99.0%.
1. The density is small. The specific gravity of pure aluminum is 2.71. Under the same volume, the weight of 1-series aluminum plate is only 35% of that of iron.
2. It can be strengthened. The strength of 1000 series aluminum coil can be increased by cold working, up to more than 1 times.
3. Easy to process. Series 1 aluminum coils have good plasticity and are more suitable for machining, such as sawing, shearing, milling, boring, planing, turning, etc.
4. Corrosion resistance. The surface of the 1-series aluminum plate without special processing will naturally form a dense layer of aluminum oxide protective film, which is difficult to be destroyed. Therefore, the 1-series aluminum plate has good resistance to the atmosphere (including industrial atmosphere, ocean, etc.) Atmospheric) corrosion and water corrosion capabilities.
5. No low-temperature brittleness, the strength and plasticity of 1-series aluminum coils will not decrease due to the decrease of temperature. Below zero, the lower the temperature, the higher the strength and plasticity will be.
6. Good electrical and thermal conductivity. Among metals, the electrical and thermal conductivity of aluminum is second only to gold, silver and copper.
7. Good reflectivity. After polishing, the reflectivity of the surface of the 1-series aluminum plate to light can reach more than 80%. The higher the purity of aluminum, the higher the reflectivity. In addition to visible light, aluminum has good reflectivity to infrared rays, ultraviolet rays, electromagnetic waves, heat radiation, etc.

Performance characteristics of 3 series aluminum coils in aluminum coils:

The 3-series aluminum coil belongs to the aluminum-manganese alloy, the main component is manganese, which belongs to the alloy that cannot be strengthened by heat treatment.
1. The 3-series aluminum coil alloy has high plasticity and good welding performance;
2. The strength is higher than that of industrial pure aluminum, and its corrosion resistance is similar to that of industrial pure aluminum. It is called anti-rust aluminum alloy with aluminum-magnesium alloy.
3. The 3-series aluminum coil alloy has good plasticity in the annealed state, and has good deep drawing performance after annealing. It is mainly used in the manufacture of automobiles, aircraft fuel tank oil pipes, containers and tanks, mechanical parts and other fields.

Performance characteristics of 8 series aluminum coils in aluminum coils:

The 8-series aluminum coil belongs to the aluminum-lithium alloy, the main component is lithium, because lithium is the lightest metal in nature, adding lithium to the aluminum plate can effectively reduce the specific gravity of the aluminum plate while ensuring the strength of the aluminum plate
1. Light weight. The biggest feature of aluminum-lithium alloy is its quality. The addition of lithium makes the aluminum-lithium alloy lighter than most metals. As the content of lithium increases, its quality will further decrease. This feature attracts many scientists to study it.
2. High strength. Aluminum-lithium alloy has high strength, and its strength will not change significantly due to the increase of lithium element, and the strength of the alloy can be further improved by adding copper, magnesium, zinc and other elements.
3. High rigidity. Aluminum-lithium alloy has high stiffness and strong deformation resistance, and its stiffness will be further improved with the increase of lithium element.
4. Anti-corrosion. Compared with pure aluminum, aluminum-lithium alloy has good corrosion resistance and strong environmental adaptability.
5. Anti-fatigue. Metal fatigue is one of the main factors limiting the application range of aluminum plates, while aluminum-lithium alloys have excellent fatigue resistance and long service life.
6. Good ductility. Aluminum-lithium alloy has good ductility, which effectively reduces the processing difficulty of aluminum-lithium alloy.
