Among the eight commonly used aluminium plates, the 1st, 3rd and 5th series are the two series which are widely used in the industry. Series 1 aluminium plate is also known as pure aluminium plate, the main brands are 1050, 1060, 3 series aluminium plate is also known as aluminium-manganese alloy, the main brands are 3003 and 3A21, 5 series aluminium plate is also known as aluminium-magnesium alloy, the main brands are 5052, 5083, 5754, 5A05 and 5A06. As the two most 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 road signs, stamping parts, low cost.
Aluminum manganese alloy: 3 series aluminium sheet has good rust resistance, 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 weight is only one third of that of the latter.
In practical applications, 3-Series aluminium sheets are mostly used in occasions requiring anti-corrosion and anti-rust performance, such as thermal insulation of pipes in power plants and chemical plants, ground anti-skid construction of refrigerators; 5-series aluminium sheets are more widely used in manufacturing industries, such as aircraft, automobiles, radiators, etc., with more commonly used brands.
