The melting point of aluminum is 660 ℃. The aluminum alloy as the different elements it contains, and between 482 ℃ -660 ℃ change its melting point. Aluminum and aluminum alloy is heated from room temperature to dissolve the state of Shandong Aluminum coil prices, no color change professional manufacturer of aluminum coil, which is close to the melting point to determine how difficult. Mechanical properties of aluminum and its alloys with changes in its purity aluminum coil manufacturer specializing in the production of higher purity, lower the intensity, the higher ductility. Minimum tensile strength as industrial aluminum rolled sheet between 70-110MPa, industrial high tensile strength aluminum only 50MPa, while the tensile strength of aluminum-magnesium alloy in the above 170MPa. Another characteristic of aluminum and aluminum alloys, with the temperature increases, the tensile strength reduced; the temperature decreases, the tensile strength is increased, the elongation increases. Aluminum and aluminum alloy, when exposed to air, will soon form a strong adhesion and thermal oxide films. Before welding, you must carefully remove this layer of the oxide film to the welding, the matrix and filler metal fusion good; when the fiber welding, brazing has good mobility. An aluminum oxide film is solvent-removable coil, may be under an inert atmosphere, removed by the action of the welding arc, or removed by mechanical or chemical methods.
