As the most abundant metal in the earth’s crust, aluminum alloy has gradually been widely used in production and life. In particular, aluminum alloys have increased hardness and strength in addition to their own corrosion resistance and plasticity after adding alloy components. In many fields, aluminum alloy profiles have been selected to replace steel. The reason is that aluminum profiles are lighter (only one-third of steel) and have more surface treatments, such as sandblasting, polishing, anodizing, coloring, electrophoresis, spraying, and more.
The density of aluminum is only 2.7, but the hardness of aluminum alloys is not proportional to the density. The aluminum alloy after adding magnesium and silicon is a light and hard metal, so it is widely used in industry, construction, and other fields.
The aluminum-magnesium alloy has strong plasticity and can be extruded to generate various complex cross-sections, while steel does not have such characteristics, and the cross-section of steel can only be processed into simple shapes through some complex processes. And the processing cost is high, time-consuming and laborious.
The corrosion resistance of the aluminum alloy profiles after surface treatment is greatly enhanced, and the service life of the aluminum alloy profiles is also greatly increased. In addition, the surface treatment methods of aluminum alloy profiles are various, and the effect like sand surface cannot be made of stainless steel. Even if it is made, the cost will be terrifyingly high. For the simplest example, now our mobile phone shells are basically made of aluminum alloy, and the surface is treated with alkaline sand or fine sandblasting to form a matte effect. In line with modern aesthetics, understated luxury.
