Discount Abrasives
Abrasives are a material that have a higher degree of hardness, and are used to shape other materials by way of abrasive actions. Abrasives usually have a hardness of 7 or more on the Moh’s scale of hardness. They are used widely in industries for cutting and shaping parts and products, and are one of the key materials used in the manufacturing sector.
Previously, naturally occurring materials and minerals were used as abrasives; however, these have given way today to synthetic abrasives. Synthetic abrasives are more suitable for certain specific applications, but they are more costly than the naturally occurring abrasives. So if one is looking for cheaper abrasives to cut down costs, natural abrasives would be recommended, especially if you don’t have a highly specific requirement. Various naturally occurring abrasives like Calcite, Diamond dust, Emery, Novaculite, Pumice dust, Rouge, and Sand (sandpaper being one of the cheapest and most commonly used abrasive) can be used as cheaper alternatives to synthetic abrasives. Certain abrasives, like Zirconia Alumina, are very rare and difficult to obtain, and thus are costly. So if there is a specific requirement to use such abrasives, its synthetic versions (same material manufactured artificially, and not procured form the mineral) would be more cost effective. However, other synthetic abrasives like Borazon, Ceramic, Corundum, Dry Ice, Glass powder, and Silicon Carbide will turn out to be more costly than their naturally occurring counterparts. Nevertheless, at times such abrasives have to be used due to certain specific requirements.
When opting for discount abrasives, especially the naturally occurring ones, you should make sure that it will do the job that is required, and hence, such abrasives should be checked for certain criteria before ordering them:
Difference in hardness so as to cut quicker, or give the desired finish on certain hard materials.
Grain size, as bigger grit or grain tends to cut the material faster and deeper.
Adhesion between grains, as this will determine how fast the grains are eroded from the abrasive surface and the new grains exposed. This will help determine how long the abrasive will last for a particular job.
The force at contact, more force will cause faster abrasion.
Whether any coolant or lubricant is required, as this will determine if it will decrease friction, transfer heat, or create undesired stresses in a work piece.
Sand is one of the cheapest materials available that can be used as an abrasive. Sand blasting is one such technique, which makes the use of sand for abrasive action, and is quite cheap compared to other options. Sand blasting is used for shaping, smoothening, or cleaning a hard surface. Solid sand particles are forced across the surface at high speeds, which causes action that is similar to that of using sandpaper. However, it provides a better uniform finish, with no difficulties in working over crannies or corners.
The downside of using this technique is that it causes silicosis after long exposure to sand particles suspended in the air during the blasting process. However, using modern protective gear, and breathing equipment, makes the sandblasting process just as safe as any other.
Thus, it is evident that if you are looking for discount abrasives for more cost effective options, it is not only readily available, but is also safe. Although, the final choice of the abrasive will depend on many different factors, but if the job can be done by certain cost effective methods without hampering the quality, then go ahead, use them!
