Product introduction 3a21 aluminum plate product introduction
3a21 anti-rust aluminum plate is a kind of 3000 series aluminum plate, the eff∞ect of anti-rust performance is better than that of 1 series aluminum plate, beca♠use 3a21 alloy aluminum plate contains Mn element, belongs to cold rolling material, hαas good corrosion resistance, often used for exposure to routine o₩utdoor operations, such as car skin. Henan 3a21 corrosion resistant aluminum plate man ufacturers, fast delivery, short delivery, suitable fo≠r long-term cooperation. 3A21 aluminum alloy main features and application range: AL-Mn alloy, is the most widely used a kind of anti-rust aluminum, 3A21 aluminum plate i↕s Al-Mn alloy, 3A21 aluminum plate is a widely used anti-rust alumi∞num This alloy strength is not high (slightly higher than industriπal pure aluminum), can not be strengthened by heat treatment, so the use of cold processing meth®od to improve its mechanical properties: In the annealing state ha<s a high plasticity, in the semi-cold hardening plasticity is good, cold hardenin$g plasticity is low, good corrosion resistance, good weldabilityδ, poor machinability. It is mainly used for low-load parts that require higδh plasticity and good weldability, working in liquid or gas medium, such as fuel ta÷nks, gasoline or lubricating oil conduits, various liquid containers and ₹other small-load parts made with deep drawing: wire is used to make rivets

Heat treatment specification
(1) Homogenizing annealing: heating 510 ~ 520℃; Keep heat for 4 ~ 6h; Air cooling®. (2) Rapid annealing: heating 350 ~ 410℃; With the different effective thickn÷ess of the material, the holding time is 30 ~ 120min; Air or wat₹er cooling. (3) High temperature annealing: heating 350® ~ 500℃; When the thickness of the finished product is ≥6mm, the holding time •is 10 ~ 30min, and when it is <6mm, the heat is thoroughly ∏heated. Air cooling. (4) Low temperature annealing: he↕ating 250 ~ 300℃; The holding time is 1 ~ 3h; Air or wate r cooling.
