Magnesium sheet and strip — very light, workable and practical in application. UD. weight of magnesium in normal conditions is = 1.7 g/cm3, t° melting point of 651 °C. of Its surface protected by the oxide film, which at 623 °C is destroyed, then the magnesium flashes and burns not only on air, but in carbon dioxide. Technical magnesium produced by the electrolysis of molten mixture of chlorides of potassium, magnesium and sodium. After the initial allocation of necessary additional cleaning. Electrolytic refining is used in a mixture with special fluxes. Chemically pure magnesium is obtained by sublimation in vacuum. Refined magnesium has impurities not more than 0.001%. Another thermal method of producing magnesium provides for the recovery of magnesium oxide by silicon or coke when heated. Price of 1 kg of magnesium ingot is about $ 3.
Magnesium flat rolled well stamped, bent, rolled, drilled and cut easily. This is one of the cheapest and most high-tech metals of the present. However, pure magnesium is quite brittle, the more valuable its alloys as structural material. The majority of its alloys are lightweight, strong and corrosion-resistant materials. Magnesium sheet and strip made from alloys with aluminum, zinc, titanium, manganese, beryllium. These alloys get bestlolitas melting under the protection of inert atmosphere. They absorb the vibration, have the widest field of use. Improved mechanical properties at high temperature is achieved additives of neodymium cerium, thorium. Cerium and zirconium modify the crystal lattice. Supplement of 0.6% Zr reduces the cross section of the grain. Zirconium, and manganese reduce the negative impact of iron and Nickel on the properties of the alloys.
The disadvantages include difficulties in melting, casting and hardening of magnesium alloys. Magnesium does not apply to heat-resistant materials. In its pure form is quite a fragile material.
Magnesium sheets are rolled lengths or dimensional, are cut from all sides, while the edges must be free of delaminations and burrs. The sheet surface must be clean, without dross, flux inclusions, bundles, cracks, tears. Acceptable minor irregularities, inconsequential roughness or traces of broach. But these defects must not go beyond the boundaries of normalized standard deviations. Where there is a fracture, the material should not contain foreign inclusions or voids. As the material sheets are divided into two groups: the annealed marking «M» and polunagartovannye marking «N». Sheet thickness more than 32 mm are produced with uncut edges and ends. Uncut on the ends and edges of any residual artifacts, however they must not go beyond the boundaries of normalized standard deviations. Surface additionally undergoes anti-corrosion treatment.
Lightweight, technologically advanced and durable sheets of magnesium alloys relevant to the automotive and aerospace industries, where it is particularly important to reduce the overall weight of the structure. Such items in the amount of greatly facilitate weight, reduce the fuel consumption and increases the efficiency of the model. Magnesium sheet is demanded for the production of parts fairings, landing gear, ailerons, doors, liners, pumps, fuel tanks. Thanks to the increasing weight, reduces fuel consumption and increases the efficiency of the motor. In the automotive industry are elements of automobile crankcase, shock absorbers, plastic molding, decorative items, covers tanks, magnesium rims for the wheels. The instrument is the body parts and instruments, cameras, mobile phones, cameras. in the automotive and aerospace industry. In automotive relevant magnesium alloys with aluminum, zinc and zirconium, operating at normal temperatures. Improved mechanical properties at high temperature is achieved additives of neodymium cerium, thorium. Cerium and zirconium modify the crystal lattice. Supplement of 0.6% Zr reduces the cross section of the grain. Zirconium, and manganese reduce the negative impact of iron and Nickel on the properties of the alloys. Magnesium alloys are especially needed in mechanical engineering for the manufacture of rotating parts have a minimum inertia; in the manufacture of lightweight tools and household appliances. The lack of interaction with the uranium was the reason for the use of magnesium rolled in the nuclear power industry
