濟南鋁板分為生鋁與熟鋁，生鋁是98%以下的鋁，性質對比脆硬，只能翻砂鑄造商品；熟鋁是98%以上的鋁，性質柔軟，可壓延或沖軋多種器皿。那么大家在選購時如何判斷鋁板的質量呢？劣質鋁板一般一般具備哪些特征呢？

1、濟南鋁板http://www.pdadn.com/如果劣質的話化學成分不合格，會致使修建鋁型材化學成分不合格，嚴重危及修建工程安全，削減了化學試劑損耗，本錢降了，但型材耐腐蝕功能也大大降低了。
Jinan aluminum if the chemical composition of poor quality, then failed, resulting in the construction of aluminum chemical composition will fail, seriously endanger the safety of construction projects, reducing the chemical reagent

consumption, cost reduction, but the profiles corrosion function is also greatly reduced.

2、濟南鋁板質量差的氧化膜厚度薄。厚度不夠，鋁型材外表易銹蝕、腐蝕。抽驗中一些無產名、廠址、生產許可證、合格證的鋁型材，其氧化膜厚度僅2至4um，有的乃至沒有氧化膜。
Jinan oxide film thickness of poor quality aluminum. Thick enough, aluminum exterior is easy to rust, corrosion. Sample testing of some proletarian name, address, production license, certificate of aluminum, oxide film thickness of only

2 to 4um, some even no oxide film.

3、濟南鋁板http://www.pdadn.com/不合格的運用時會由于空氣、雨水、陽光等影響，致使鋁型材變形，乃至形成玻璃決裂、掉落等表象。
Jinan failed when using aluminum due to the air, rain, sunlight and other factors, resulting in deformation of aluminum, as well as the formation of glass break, falling, etc. appearance.
