Mingtai Aluminum introduces the difference between aluminum and aluminum alloy

Edit:admin001 Date: 2019-05-17 14:13
Aluminum is a product that you will often see in your life. The application of aluminum alloy is very wide. So is it good for aluminum or aluminum? Let's analyze the difference between the two today. You can also see in this analysis. The advantages of both come.
First, the introduction of aluminum
Aluminum is a light metal in non-ferrous metals with a density of 2.71 g/cm3 and silver white. Aluminum has good electrical conductivity and thermal conductivity, and its chemical properties are also very active. When exposed to air, the surface is prone to form an aluminum oxide film to protect the underlying metal from corrosion. Therefore, aluminum has high corrosion resistance in the atmosphere. However, since the film is extremely thin, its corrosion resistance has a certain limit. Pure aluminum has good plasticity and can be made into tubes, rods, plates, and the like. Aluminum has lower strength and hardness. The polished surface of aluminum has a reflectivity of more than 80% for white light, and has a strong reflective ability for ultraviolet rays and infrared rays. Aluminum can also be surface-colored to provide a good decorative effect.
Second, the introduction of aluminum alloy
Aluminum alloy is composed of elements such as magnesium, manganese, copper, zinc, and silicon added to aluminum in order to improve the practical value of aluminum. There are many types of aluminum alloys, and the aluminum alloy used for architectural decoration is a wrought aluminum alloy in a deformed aluminum alloy. The forged aluminum alloy is an aluminum-magnesium-silicon alloy, in which the LD31 has medium strength, high impact toughness, excellent thermoplasticity, and can be extruded at high speed into various structurally complex, thin-walled, hollow profiles or forged structurally complex forgings. LD31 has excellent welding performance and corrosion resistance. The surface is very smooth and easy to color after processing. It is the most widely used alloy in AI-Mg-St alloy. Aluminum alloy decorative products include: aluminum alloy doors and windows, aluminum alloy curtains, aluminum alloy decorative panels, aluminum foil, magnesium aluminum decorative panels, magnesium aluminum curved panels, aluminum alloy ceiling materials, aluminum alloy railings, handrails, screens, grilles, etc. Aluminum foil refers to a sheet product processed from pure aluminum or niobium alloy to 6.3 pm to 0.2 mm. Aluminum foil has good moisture resistance and thermal insulation properties, so aluminum foil is widely used in the construction industry with new multifunctional insulation materials and moisture-proof materials; for example, coiled aluminum foil can be used as thermal insulation curtains, sheet aluminum foil (such as aluminum foil corrugated board) , aluminum foil foam plastic board, etc.) are commonly used indoors, by choosing the appropriate color pattern, it can also play a good decorative role at the same time.
Third, the difference between aluminum and aluminum alloy
As can be seen from the above, aluminum and aluminum alloys differ greatly in composition. Aluminum alloy is composed of magnesium, manganese, copper, zinc, silicon and other elements added to aluminum. Due to the different ingredients, the two are used in many different fields, so choosing to use the product is not only good or not, but also inappropriate.
