Properties of aluminum grain

Aluminum grain aka pills aluminum, aluminum sand, aluminum particles with 99% aluminum batten again drawing, cutting, cutting action and refined. The apparent ablaze appearance, terete, acclimated in aluminum, zinc or thin-walled workpiece. Blast cleaning, has accessible whitening aftereffect on workpiece surface. Apparent finishing processing is broadly acclimated in aluminum casting and copper, zinc castings, all kinds of metal apparent sandblast, burr, brier removing casting workpiece, brand surface, casting articles apparent sandblast etc.. Can accomplish your articles collapsed and smooth, shiny, accomplish the whitening effect. At the aforementioned time, aluminum particles and can be acclimated with a stainless animate grit, stainless animate bolus participation, accomplished on the workpiece apparent brighter and whiter effect. It has the ductility and malleability. Articles are fabricated of rod-like, sheet, foil, powder, award and filamentous. In the boiling air can anatomy a band of oxide blur to anticipate metal corrosion. Aluminum and aluminum antithesis and acrimonious in air afire fiercely, and emits a blinding white flame. Soluble in adulterate sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, baffling in water. The about body of 2.70. The melting point of 660 DEG C. Boiling point is 2327 ℃.

Because aluminum grain active and strong, not simple to be reduced, appropriately it was begin later. The 1800 Italy physicist Voet created the array afterwards 1808 ~ 1810 years, British chemist David and the Swedish chemist Betsy Rius Du approved to use the accepted break of aluminum from bauxite, but afterwards success. Betsy Rius gave this bootless to access the metal has a name alumien. This is from the Latin alumen. The noun in medieval Europe is a accepted appellation for a accumulation of aggregation of alum, refers to the acerbic dye cotton. Aluminum Latin name afterwards aluminium and attribute of aspect Al is the resulting. In 1825, Danish chemist Oster appear beginning alertness of aluminum after. In 1827, the German chemist Vul again the oersted's experiment, and continuously advance the assembly adjustment of aluminum. In 1854, the German chemist Deweier use instead of potassium sodium abridgement aluminum chloride, metal aluminum ingots prepared. Aluminum has acceptable ductility ( ductility it additional alone to gold and silver), at 100℃ ~ 150 ℃can be fabricated of aluminum antithesis thinner than 0.01 mm. The aluminum antithesis is broadly acclimated for packaging cigarettes, bonbon and so on, can aswell be fabricated of aluminum wire, aluminum strip, and rolling all kinds of aluminum products.
