Spirit of magnesium board

Introduction magnesium plate as the lightest practical metal plate having a large specific strength and specific stiffness, heat resistance, shock absorption, easy cutting and electromagnetic interference shielding and good. Magnesium plate strength and elastic modulus than the plastic of high unit weight, in the same strength, thin and lightweight magnesium alloy components than plastic parts. Strength aluminum magnesium alloy and iron is higher than in the case without reducing the strength of the magnesium alloy parts can reduce a lot of weight. Mobile phone, the size of the LCD screen on the laptop is growing, magnesium alloy parts and more widely used in branch support frame and the back of the housing. Magnesium alloy parts several times higher heat resistance than plastic, which can effectively distribute the heat inside electrical products. Magnesium alloy casing and magnesium alloy heat dissipation member computers and projectors and other electronic products that can better distribute the heat generated inside temperature. TV magnesium alloy casing can be done without vents. Electromagnetic shielding properties of magnesium alloy plating than plastic shielding effect is good film, mobile phone casing and magnesium alloy shielding materials can save electromagnetic wave shielding film plating processes. Magnesium plate than other metal cutting resistance, machining faster. As one of the most important AZ31B wrought magnesium alloys are widely used in 3C consumer electronics products to meet its highly integrated, lightweight, miniature, anti-beat hit, electromagnetic shielding, thermal performance, absorb noise, vibration, anti- radiation and environmental applications. As a well-structured materials, magnesium plate in transportation manufacturing, military manufacturing, office products, 3C consumer electronics (such as mobile phones, portable notebook computers, digital products, etc.) have been widely used. I. Application: 3C consumer electronic products and product components, such as mobile phones, laptops, digital cameras, projectors, PDA, CD machine, MP3, portable DVD, walkie-talkie; for the production of templates, vibrators, engraving and printing industry. Mobile phone, branch and back support frame on the laptop case. Second, the chemical composition: Our company produces magnesium alloy AZ31B follow ASTM B90 / B 90M standard, specifically: Alloy Mg Al Zn Mn Ca Cu Fe Ni Si Other Total AZ31B margin 2.5-3.5 0.60-1.4 0.20-1.0 ≤0.04 ≤0.05 ≤0.005 ≤0.005 ≤0.10 ≤0.30 III Specification: sheet thickness: 0.6-6.3mm sheet width: 500-1000mm sheet length: 800-2000mm maximum size: 0.6 mm X 600 mm X3000 mm Availability: O, H18 , H24 four, product performance gravity: 1.78g / cm3; Specific heat: room temperature 1.04KJ / kg / k; Thermal conductivity: at room temperature 76.9W / M / K; resistivity: at room temperature for 92 nΩm Melting point: 596 ℃; crystals size (depending on the status of the different supply vary): 5 ~ 15μm; elongation (depending on the status of the different supply vary): at room temperature for 15 to 21 percent; tensile strength (depending on the status of the different supply vary): at room temperature 250 ~ 290Mpa; yield strength (depending on the status of the different supply vary): at room temperature 180 ~ 220Mpa; (including condensate under atmospheric conditions) fatigue strength: 140 Mpa at room temperature under 6X10000 cycle times; hardness (somewhat different depending on supply status Change): room temperature 56 ~ 75Hb; damping coefficient (depending on the state of different supply vary): 30 to 60 (aluminum alloys 2 to 5);
