2A12 Aluminum is a typical hard aluminum alloy with moderate alumium, copper and magnesium content. Its alloy composition ratio is reasonable, and the overall performance is good. 2A12 aluminum plates are also the largest in terms of global duralumin consumption.
2A12 aluminum alloy features high strength, a certain degree of heat resistance, which can be used as working parts below 150 ℃. At temperatures higher than 125 ℃, its strength is higher than that of 7075 alloys.
The forming properties in the hot state, annealing and new quenching state are relatively good, and the heat treatment strengthening effect is significant, but the heat treatment process requirements are strict.
Its corrosion resistance is poor, but it can be effectively protected by covering with pure aluminum; it is easy to produce cracks during welding, but it can be welded or riveted by special technology.
2A12 aluminum sheet is is very suitable for the production requirements of the machinery manufacturing industry. It is also widely used in aircraft structures, rivets, truck wheels. More and more manufacturers are beginning to use 2A12 aluminum sheet as their raw material.
2A12 aircraft aluminum is high-strength duralumium that its Mg content is increased to 1.5%, and it contains higher Mn content. The high temperature strength of this duralumin is higher than that of standard duralumin and super duralumin. The 2A12-T4 alloy aluminum plate has high strength and qualified plasticity. It is the most widely used hard aluminum in the aviation industry.
Because 2A12 aluminum plate contains high Cu, its corrosion resistance is lower than that of pure aluminum and Al-Mn alloy. Therefore, the corrosion resistance of 2A12-T4 aluminum in the ocean and humid atmosphere is very low, which cannot meet the requirements of use and needs to be artificially protected.One of the protection methods is to use pure aluminum plate with a purity over 99.5% to cover its surface.
Haomei Aluminum has a strict control of Cu and Mg content, so that the tensile strength and natural aging effect of quenching of 2A12 alloy can be greater. We can offer 2A12 aluminum sheets in O , T3, T4, T351, and H112 tempers. Welcome to leave message below to inquire it.
