Do you use aluminum alloy boards or aluminum plates for outdoor billboards?
Aluminum alloy low density, but relatively high strength, close to or higher quality steel, plastic good, can be processed into various profiles, with excellent conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of only steelIn general, outdoor billboards are made of aluminium alloy sheets
Pure aluminum density (P =2.7g/cm3), iron is about 1/3, the low melting point (660 C), aluminum is face centered cubic structure, so it has high plasticity (delta psi:: 32~40%, 70~90%), easy processing, can be made into various sections and plates. The corrosion resistance is good; but pure aluminum strength is very low, the annealed state sigma B is about 8kgf/mm2, it is not as a structural material. Through the long-term production practice and scientific experiments, people gradually to join the alloying elements and the use of heat treatment to strengthen aluminum, which has been a series of Aluminum Alloy. Adding alloy elements to form certain can with high strength in keeping advantages of pure aluminum etc. at the same time, a b value can reach 24 ~ 60kgf/mm2. so that its "strength" (strength and the ratio of the proportion of b/ sigma rho) more than a lot of steel structure become an ideal material, widely used in machinery manufacturing, transport Machinery, power machinery and aviation industry, aircraft fuselage, skin, compressor and so on, often made of aluminum alloy, in order to reduce the weight. Using aluminum alloy instead of steel plate welding, the structure weight can be reduced by more than 50%
Aluminum Alloy is a kind of nonferrous metal structural materials widely used in industry, has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industry. In recent years, with the rapid development of science and technology and industrial economic structure, increasing demand for Aluminum Alloy welding, the welding of aluminum the alloy also further widely used. Aluminum Alloy promoted the development of welding technology Aluminum Alloy, at the same time the development of welding technology and expand the application field of Aluminum Alloy, so Aluminum Alloy welding technology is becoming the research hotspot. A Aluminum Alloy: aluminum based alloy in general. The main alloying elements copper and silicon, magnesium, zinc and manganese, minor alloying elements such as nickel, iron, chromium, titanium, lithium and so on.
