Aluminum alloy flange is a part connecting pipes, which is used to connect pipe ends. It is also very useful for the flange on the inlet and outlet of equipment, which is used to connect two devices, such as the flange of reducer. Flange connection or flange joint refers to the detachable connection in which flanges, gaskets and bolts are connected with each other to form a set of combined sealing structure.

The common material brands of aluminum alloy flanges are: 606 1 aluminum flange, 6060-T6 aluminum flange, 5083 aluminum flange, 5083-H 18 aluminum flange, 1060 aluminum flange, 6060 aluminum flange, etc.

Aluminum in aluminum alloy flange is silvery white light metal. Ductility can form an oxide film to prevent metal from corroding in humid air. Aluminum powder and aluminum foil can burn violently when heated in air, giving off a dazzling 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℃. The boiling point is 2327℃. The content of aluminum in the earth's crust is the third only to oxygen and silicon, and it is the most abundant metal element in the earth's crust. The development of three important industries, aviation, construction and automobile, requires that aluminum and its alloys have unique properties, which is of great benefit to the production and application of this new metal aluminum. It is widely used.
