Aluminum Flux Powder
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. The development of three important industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which is greatly beneficial to the production and application of this new metal aluminum. The application is extremely extensive.
The Aluminum Flux Powder is a white powder or granular flux. After drying by a variety of inorganic salts, it is prepared by mixing in a certain ratio.
Aluminum Flux Powder Function
The refining agent is mainly used to remove the hydrogen inside the aluminum liquid and the floating oxidized slag, so that the aluminum liquid is more pure and has the function of clearing slag.
Aluminum Flux Powder Characteristics
Some components in the refining flux are easily decomposed at high temperature, and the generated gas is easy to react with hydrogen, and has strong adsorption force with slag and quickly escapes from the melt. The other components have a slag-removing agent effect.
Aluminum Flux Powder Application Scope
Suitable for aluminum alloys with common grades (alloys with high magnesium content and aluminum-magnesium alloys), and pure aluminum smelting, degassing refining and slag removal.
Aluminum Flux Powder Usage
The refining agent is sprinkled on the liquid surface, and is quickly pressed into the aluminum liquid. After being fully stirred, it is allowed to stand and slag; if it is sprayed, the effect of injecting the refining agent into the aluminum liquid with an inert gas is better.
Silver white light metal. It is malleable. The product is often formed into a rod shape, a sheet shape, a foil shape, a powder shape, a ribbon shape, and a filament shape. An oxide film that prevents corrosion of metals can be formed in humid air. The aluminum powder is heated in the air to burn violently and emit a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, difficult to dissolve in water. The relative density is 2.70. The temperature of 660 ° C. The boiling point is 2327 ° C.
