3003鋁方管化學(xué)性能
耐蝕性：3003鋁管的耐蝕性很好，接近工業(yè)純鋁的耐蝕性，對大氣、淡水、海水、食品、有機(jī)酸、汽油、中性無機(jī)鹽水溶液等均有良好的耐蝕性，在稀酸中的耐蝕性也很好。 在冷變形狀態(tài)時，3003鋁合金有剝落腐蝕傾向，變形越大，剝落越嚴(yán)重。由于陽極氧化后色彩不均勻，故一般不進(jìn)行陽極化處理。
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.
