The aluminum alloy air grille has high mechanical strength, but low corrosion resistance. Although pure aluminum has good corrosion resistance, it has poor mechanical strength, which restricts the use of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types of aluminum, which greatly improves the mechanical strength of aluminum and greatly expands the scale of use.
But the corrosion resistance is worse than pure aluminum, so it may be corroded by oxidation. This requires powder coating to maintain the combined gold tuyere factory room. The aluminum alloy air grille coated by powder has high corrosion resistance. It also has many advantages such as diversified colors and good appearance texture.
