3003铝方管化学性能
耐蚀性：3003铝管的耐蚀性很好，接近工业纯铝的耐蚀性，对大气、淡水、海水、食品、有机酸、汽油、中性无机盐水溶液等均有良好的耐蚀性，在稀酸中的耐蚀性也很好。 在冷变形状态时，3003铝合金有剥落腐蚀倾向，变形越大，剥落越严重。由于阳极氧化后色彩不均匀，故一般不进行阳极化处理。
3003 square aluminum chemical properties
Corrosion resistance: the corrosion resistance of 3003 aluminum good corrosion resistance, close to the industrial pure aluminum, corrosion resistance of the atmosphere, fresh water, sea water, food, gasoline, neutral organic acid, inorganic salt solution has good, is also very good in corrosion resistance in dilute acid. During cold deformation state, 3003 aluminum alloy has the spalling corrosion, deformation is large, the more serious. Because after anodic oxidation uneven color, so they are not performing anodizing.
