CNC Aluminum Machining
Aluminum is a metallic element with the symbol Al, a malleable silver-white light metal. Commodities are often made into rods, flakes, foils, powders, ribbons and filaments. In humid air, an oxide film can be formed to prevent metal corrosion. Aluminum powder can burn violently when heated in the air, and emit a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. The relative density is 2.70. The melting point is 660°C. The boiling point is 2327°C. The content of aluminum in the earth’s crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth’s crust.
Aluminum’s light weight and corrosion resistance are two outstanding features of its performance.
