[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:
(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.
CBN is a man-made Superabrasive that outperforms Diamond when used for Ferrous grinding operations.
CBN derives its name from its chemical makeup, of the cubic form of boron nitride (CBN). It has a very desirable characteristic that is sought after when working with difficult to grind (DTG) materials.
Due to its high thermal stability and chemical resistance, the CBN grinding wheel is most suitable for grinding hard ferrous materials, hardened steel, bearing steel, nickel based alloys. machining ferrous materials.
CBN Grinding Wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish.
Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures. When you`re tools become dull over time from use, a CBN wheel will bring them back to its sharp use.
Kemei produce CBN(cubic boron nitride)grinding wheels, which can be resin bonded CBN wheel, metal bonded CBN wheels and electroplated Diamond Grinding Wheels. For same steel parts, you can choose all three types CBN wheels, but there still some difference, if you need more information and the best solutions ,please contact us.
