Aluminum gussets are "hats" for kitchens and bathrooms, and quality and quality are very important. The following five aspects should be noted when selecting.

Look at the surface treatment process of aluminum buckle plate
There are mainly five kinds of aluminum buckle surface treatment process, namely, spraying, paint, film, roller coating, AO anodizing process. Among them, spraying and baking paint plates are prone to color difference and have a shorter service life. Coated and roller-coated plates have no color difference and have a long service life. AO anodizing plates use aluminum and its alloys as anodes in corresponding electrolytes (such as sulfuric acid, chromic acid, oxalic acid, etc.), under specific conditions and applied currents. Next, conduct electrolysis. The aluminum molecular structure is changed so that a protective layer is formed on the surface of aluminum, that is, the aluminum or alloy part of the anode is oxidized, the surface of the aluminum oxide layer is formed, the wear resistance and hardness are improved, and the corrosion resistance is enhanced. Excellent performance, heat resistance, insulation, breakdown voltage up to 2000V, a large number of microporous adsorption capacity in the oxide film layer, AO process can be guaranteed to not fade.
Look at the substrate material of aluminum gussets
China's aluminum is mainly divided into ordinary aluminum, wide aluminum, southwest aluminum, the former is recycled aluminum, the latter are all native aluminum.
See if recycled aluminum
Ordinary coated sheet substrates are made of recycled aluminum (recycled aluminum products such as cans, old aluminum pans, and aluminum filaments, etc. are recoated and reprocessed). Since the recycled aluminum material is re-processed many times, its aluminum Low purity, many impurities, poor environmental performance, contains certain heavy metals, such as lead, chromium, nickel, potassium, etc., high lead content, lead to lead poisoning (many manifested as hyperactivity in children, lack of concentration, memory loss, etc.) Therefore, the cost of recycled aluminum is low. At the same time, the recycled aluminum has low strength, flatness, poor toughness, and is not evenly leveled after being installed.
Look at the substrate
The quality of the coated substrate is better than that of the aluminum-magnesium alloy substrate produced by the Southwest Aluminum Plant, which has stable domestic aluminum processing performance. The substrate is directly derived from the mineral raw aluminum, followed by magnesium and a small amount of manganese. Processed. Because raw materials are directly extracted from minerals, their raw materials are of high purity aluminum, less impurities, and non-toxic environmental protection. At the same time, they have good flatness, flat surface, high toughness, and no deformation, so the cost of the product is higher than that of recycled aluminum.
Identification of recycled aluminum and native aluminum
Compared with the original aluminum metal has a unique metal texture and luster, from the cross-section to see the substrate metal gloss is strong and bright; while the recycled aluminum due to its own impurities more than the product does not have the unique texture and gloss of the metal, from the cross-section to see The material shows a dull, non-metallic luster.
