Among the eight commonly used aluminium plates, the 1st, 3rd and 5th series are two series which are widely used. Series 1 aluminium plate is also known as pure aluminium plate, the main trademark: 1050, 1060, 3 series aluminium plate is also known as aluminium-manganese alloy.
The main trademarks are 3003 and 3A21,5 series aluminium plates, also known as aluminium-magnesium alloys. The main trademarks are 5052, 5083, 5754, 5A05 and 5A06. As the two most widely used alloys, what are the specific differences between Al-Mn alloy and Al-Mg alloy?
Pure aluminium sheet: 1 series aluminium sheet is mostly used in highway signs, stamping parts, low cost.
Aluminum-manganese alloy: 3 series aluminium sheet has good rust-proof function, good formability, high corrosion resistance and high strength.
Al-Mg alloy: 5-series aluminium sheet has light weight, high strength, corrosion resistance, easy coloring, low density, good heat dissipation and strong compressive resistance. It can fully meet the requirements of high integration, lightness, miniaturization, anti-collision, electromagnetic shielding and heat dissipation of 3C products. Its hardness is several times that of the traditional plastic case, but its component is only one third of that of the latter.
In practical application, three series aluminium sheets are mostly used in occasions requiring anticorrosion and rust-proof functions, such as heat preservation of pipes in power plants and chemical plants, ground anti-skid construction of refrigerators; five series aluminium sheets are more used in manufacturing professions, such as airplanes, automobiles, radiators, etc., with wider use and more commonly used trademarks.
