Aluminum plate is a common raw materials in the production of mesh, aluminum plate division is mainly divided into pure aluminum and aluminum alloy plate. Pure aluminum is what we usually call ordinary aluminum plate, generally is pure aluminum plate 1060.

Aluminum alloy are mainly aluminum alloy and aluminum alloy 3003, 5052 aluminum alloy is the most widely used a kind of antirust aluminum, but the strength of the aluminum alloy 5052 is higher than aluminum alloy 5052, the strength of the aluminum alloy 3003 was slightly higher than that of industrial pure aluminum, with strong plastic with high corrosion resistance, fatigue resistance can't heat treatment reinforcement, corrosion resistance, good weldability, cutting performance is bad, can be polished. Aluminum perforated plate is mainly used for high plasticity and good weldability environment.

Aluminum alloy is the most widely used in industry of non-ferrous metal structural materials, in aviation, aerospace, automotive, machinery manufacturing, shipping and have been extensively applied in chemical industry. An alloy of aluminum alloy, aluminium as base. Main alloying elements are copper, silicon, magnesium, zinc, manganese, secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc. The density of pure aluminum (rho = 2.7 g/cm3), is about 1/3 of the iron, low melting point (660 ℃), aluminum is face-centered cubic structure, therefore, has the very high plasticity (delta: 32 ~ 40%, and bits of: 70 ~ 90%), easy to machining, can be made into various molding, plate. Corrosion resistant performance is good; But the strength of pure aluminium is very low, annealing state sigma b value is about 8 KGF/was, therefore, not as a structural material. Through the long-term production practice and scientific experiment, people gradually to add alloy elements and using the method of heat treatment to strengthen aluminum, it's got a series of aluminum alloy. Add some elements to form the alloy while maintaining the advantages of pure aluminum light can also has high strength, sigma b value can reach 24 ~ 60 KGF/was respectively. So that its "strength" (the ratio of intensity and the proportion of sigma b/rho) is better than a lot of alloy steel, become the ideal structural material, widely used in machinery manufacturing, transportation, machinery and aviation industry, the aircraft fuselage, skin, such as compressor with aluminum alloy manufacture, in order to reduce weight. The welding of aluminum alloy instead of steel material, the structure can reduce more than 50% in weight.

Aluminum alloy density is low, but the intensity is high, close to or more than high-quality steel, plastic, can be processed into various profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used on industry, usage is second only to the steel. General use of outdoor billboards in the majority with aluminium alloy plate.
