INFORMATION ABOUT ALUMINUM SANDBLASTING
You can find information and explanations about aluminum sandblasting on this web page. Aluminum or aluminium is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is remarkable for the metal's low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium and its alloys are vital to the aerospace industry and important in transportation and structures, such as building facades and window frames.
Due to its convenient properties (high resistance to corrosion, good mechanical properties, low density etc.) and to a large presence in the earth crust, the aluminum is used in a high extend in various industrial fields. One must mention that not only the technical aluminum is used, but also the aluminum alloys are materials applied to solve various problems in machine building. Even the aluminum and some of its alloys have a high resistance to the oxidation phenomena, there are situation when the surfaces of aluminum parts must be cleaned or prepared for other operations and one of the techniques applied with this aim in view is the sandblasting. Aluminum sandblasting is the process where small angular or spherical particles are propelled at a part by compressed air, or mechanical high speed rotating wheels or water pumps.
Aluminum sandblasting is performed to achieve the purposes of aluminum surface cleaning, surface roughness or surface texture. General sandblasting priciples are acceptable for aluminum sandblasting. The blast media type, shape, size, density, and hardness, along with media acceleration and volume of media, combined with blasting distance from the workpiece, angle of impact and time cycles are important factors in the blast process capabilities. The blasting equipment is produced to deliver, reclaim and contain the media, contain the part to be blasted and collect the dust from the blasting process. Parts can be processed individually as a batch process or can be automated thru the system.
Considering Aluminum Sandblasting, it is important to know the differences in blasting media, since different abrasive blasting media are required for different applications. Blasting media can be used for purposes such as cleaning, stripping, etching, strengthening and polishing. In addition to the media type, grit or mesh size is another factor to consider for your application. The final choice of media depends on the nature of the work required and on the blasting equipment that is employed.
Aluminum because it is a soft metal, sandblasting abrasive to be used should be chosen carefully. Hard and sharp-edged abrasives can cause unwanted damage to the surface. We recommend the sandblasting abrasives of glass beads, stainless steel shots and ceramic shots primarily for aluminium sandblasting. Depending on the purpose of sandblasting aluminum; plastic abrasive, blasting soda or walnut shell granules are also used.
