Aluminum alloy profiles with its small proportion, easy processing and mechanical strength and other characteristics, over the years has been widely used in the building doors and windows and curtain walls and other products. Aluminum is a kind of light metal with silver and white luster.
Aluminum alloy corrosion resistance has the following two characteristics:
The higher the purity, the better its corrosion resistance, mainly because pure aluminum in the air and oxygen had a certain role in the production of aluminum on the surface of a very thin and very dense natural oxide film, it should It is much faster and thicker than other metal oxide films, although it prevents further corrosion of harmful gases and moisture in the air, but it also protects it.
Aluminum alloy profile of the mechanical strength is relatively high, but its low corrosion resistance. Although the corrosion resistance of pure aluminum is good, but the mechanical strength is very poor, which in a certain extent, just restricts the application of aluminum, so people in the aluminum by adding the right amount of magnesium, copper and other zinc Metal, made of various types, and will make the mechanical strength of aluminum greatly improved, the scope of application is also greatly expanded, but its corrosion resistance than pure aluminum, so it may be due to oxidation corrosion. This time we need to carry out the powder coating to protect the aluminum alloy profiles.
After the powder coating of aluminum alloy in addition to its relatively high corrosion resistance, it also has a variety of color, the surface texture and many other advantages, and a variety of colors of the external walls of the building echoes to adapt Different building style.
