--Heat Sink Aluminum

 Light silver metal. It's malleable. Commodities are often made into bars, sheets, foils, powders, ribbons and filaments. An oxide film can be formed in moist air to prevent metal corrosion. Aluminum powders burn fiercely in the air, creating a blinding white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, but insoluble in water. Relative density 2.70. Melting point is 660 ℃. The boiling point of 2327 ℃. Aluminum is the most abundant metal element in the earth's crust, ranking third only after oxygen and silicon. The development of aviation, construction and automobile three important industries requires that the material characteristics have the unique properties of aluminum and its alloys, which is greatly conducive to the production and application of this new metal aluminum. It is widely used.f couplings.
