Aluminum Cleaner/Briahtener Acid Cleaner for Aluminum Wheels and Trailers... 

Any welded reoair on aluminum wheel(s) on a steering axle. 

The leading powder is epoxy resin, applied 1 to 50 mils thick this is used for corrosion resistance in auto underbodies, steel rebars for concrete, petroleum industry, appliances, and citrus food cans. Epoxy-polyester powders are more resistant to yellowing and are used 1 to 20 nuls thick for aluminum wheels and architectnral trim. Polyester-polyurethane powders are smooth, flexible, and weather resistant 1 to 3 mil films are used for auto trim, steel wheels, fighting fixtures, patio furniture, and appliances.

Aluminum wheels with steel or plastic ball bearings. Used in applications where weight is a factor, particularly for portable conveyors. Plastic ball bearings should be used in corrosive atmospheres. 

An often overlooked element of application is contact wheels which are used to drive and support the abrasive belt products while controlling the degree of aggressiveness and finish required. Wheels can be made from a variety of materials, such as steel, aluminum, rubber, urethane, and cloth. The most common types are rubber coated aluminum wheels, serrated on their surface. A soft rubber contact wheel will allow the coated abrasive products to cut smoothly, but be less effective in removing stock than a harder rubber wheel. The serrations are designed to improve the coated abrasives aggressiveness. This usually extends the life of the coated products by reducing the level... 

Transportation. Both wrought and cast aluminum have found wide use in automobile construction. Aluminum sand, die, and permanent mold castings are critically important in engine construction. Cast aluminum wheels are growing in importance. Aluminum sheet is used for hoods, tnmk decks, bright finish trim, air intakes, and bumpers. Because of weight hmitations and desire to increase effective payloads, manufacturers have intensively employed aluminum cab, trailer, and truck... 

Corundum. Comndum [1302-75-5] (see Aluminum compounds) is a naturally occurring massive crystalline mineral composed of aluminum oxide. It is an impure form of the gems mby and sapphke. Prior to 1900 comndum was an important abrasive for the production of grinding wheels. Today it is mainly employed as a loose abrasive for grinding and polishing optical lenses. Almost all the world s supply of comndum now comes from Africa, primarily from Zimbabwe. 

Fluorotitanic acid is used as a metal surface cleaning agent, as a catalyst, and as an aluminum finishing solvent (see Metal surface treatments). Fluorotitanates are used in abrasive grinding wheels and for incorporating titanium into aluminum aHoys (see Abrasives Aluminumand aluminum alloys). 

Hexafluorozirconic acid is used ia metal finishing and cleaning of metal surfaces, whereas the fluorozirconates are used in the manufacture of abrasive grinding wheels, in aluminum metallurgy, ceramics industry, glass manufacturing, in electrolytic cells, in the preparation of fluxes, and as a fire retardant (see Abrasives Metal surface treati nts). 

Pulpstones. Improvements have been made in the composition and speed of the grinding wheel, in methods of feeding the wood and pressing it against the stone, in control of power to the stones, and in the size and capacity of the units. The first pulpstones were manufactured from quarried sandstone, but have been replaced by carbide and alumina embedded in a softer ceramic matrix, in which the harder grit particles project from the surface of the wheel (see Abrasives). The abrasive segments ate made up of three basic manufactured abrasive siUcon carbide, aluminum oxide, or a modified aluminum oxide. Synthetic stones have the mechanical strength to operate at peripheral surface speeds of about 1200—1400 m /min (3900 to 4600 ft/min) under conditions that consume 0.37—3.7 MJ/s (500—5000 hp) pet stone. 

Historically, strontium metal was produced only in very small quantities. Rapid growth of metal production occurred during the late 1980s, however, owing to use as a eutectic modifier in aluminum—silicon casting alloys. The addition of strontium changes the microstmcture of the alloy so that the siUcon is present as a fibrous stmcture, rather than as hard acicular particles. This results in improved ductility and strength in cast aluminum automotive parts such as wheels, intake manifolds, and cylinder heads. 

Chromium Oxide is present in just about every maintenance shop in the world. We call it the GRINDING WHEEL The abrasive material in your electric grinding wheel Is Chromium Oxide. Cheap wheels may tend to use aluminum oxide.
