GB/T 3190-2008 in English

《GB/T 3190-2008变形铝及铝合金化学成分》由TC243（全国有色金属标准化技术委员会）归口，TC243SC2（全国有色金属标准化技术委员会重金属分会）执行，主管部门为中国有色金属工业协会。
本标准代替ＧＢ／Ｔ３１９０―１９９６《变形铝及铝合金化学成分》。本标准规定了变形铝及铝合金的化学成分。
本标准适用于以压力加工方法生产的铝及铝合金加工产品（板、带、箔、管、棒、型、线和锻件）及其所用的铸锭和坯料。本标准与ＧＢ／Ｔ３１９０―１９９６相比，主要变化如下：
―――新增加１３０个铝及铝合金牌号与成分，并将化学成分表一分为二：表１适用国际牌号，共收录牌号１５９个；表２适用为四位字符牌号，共收录牌号１１４个；
―――增加了对有毒有害元素的特殊控制要求；
―――增加了极限数值的表示方法；
―――修改了《新旧牌号对照表》（附录Ａ）。

1 Scope
This standard specifies chemical composition of wrought aluminium and aluminium alloy.
This standard is applicable to aluminium and aluminium alloy products (plate, strip, foil, pipe, stick, section, line and forging) produced with press working, and cast ingot and blanks used for them.

3 Requirements
3.1 Chemical composition
3.1.1 The chemical compositions of wrought aluminiums and aluminium alloys shall meet the requirements of Table 1 and Table 2. The column "others" indicates the metallic element not listed in the table. The content in the table, as single numerical value, is the minimal limit for aluminium; it is maximal limit for other elements. the denotation of limit value is as:
Limit Value of the total ferrum and silicon with the designation 1XXX 0.ΧΧ or 1.XX;
Other Limit Values:
