[China Aluminum Industry Network] Aluminum alloys have been widely used in buildings, doors, windows, curtain walls and other products for many years due to their small specific gravity, easy processing, and large mechanical strength. Aluminum is a more active light metal with silvery white luster, and its corrosion resistance has the following two characteristics: We have two types PTO pumps, PTO gear pump and PTO vane pump. this kind of pump can driven by truck engine and electric motor. Our PTO pump been used to transfer diesel fuel oil. engine oil, lube oil, lubricating oil , gasoline etc oil. pump small size, great strength, easy operation, low price.

(1) The higher the purity, the better the corrosion resistance, mainly because pure aluminum reacts with oxygen in the air, producing a thin layer of dense natural oxide film on the aluminum surface, which is faster than other metal oxide films. Thickness, and thus prevented the further corrosion of harmful gases and moisture in the air, played a protective role;
(2) Aluminum alloy has high mechanical strength but low corrosion resistance. The corrosion resistance of pure aluminum is good, but its mechanical strength is poor, which restricts the application of aluminum to a certain extent. For this reason, people add appropriate amounts of magnesium, copper, zinc, and other metals into aluminum to make various types of aluminum. Aluminum alloys greatly increase the mechanical strength of aluminum and greatly expand its application range, but its corrosion resistance is worse than that of pure aluminum, and it may be corroded by oxidation. This requires powder coating to protect the aluminum profiles.
In addition to the high corrosion resistance, the powder-coated aluminum profiles have many advantages such as multi-colors, good surface texture, and the like, and echoes with various colors of architectural exterior wall coatings to adapt to different architectural styles.
