    Summary:
    (1) Nomenclature The naming of non-ferrous metal and alloy product grades requires the use of Chinese pinyin letters or international element symbols as the subject code to indicate the category to which it belongs, such as L or AL for aluminum and T or Cu for copper. After the keyword, it is represented by the component number order in combination with the product category. That is, the code number after the subject word can indicate the state, characteristics or main components of the product, such as LF is aluminum (L) alloy for preventing (F) rust; LD is aluminum (L) alloy for forging (D); LY is hard (Y) Aluminum (L) alloy, the key words of these three alloys are aluminum alloy (L). For example, QSn is the main additive element in the green (Q) copper is tin (Sn); QAL9-4 is aluminum (Q) in the green (Q) copper, and the elemental aluminum added in the composition is 9%. The element is 4% and the subject of these two alloys is bronze (Q). Therefore, the product code is represented by a combination of the subject Chinese pinyin letters, chemical element symbols and Arabic numerals specified in the standard (GB340-78).
    The state, processing method and feature code of non-ferrous metals and alloy products are indicated by the specified Chinese pinyin letters. Such as hot processing R (heat), quenched C (quenching), aluminum without B (not), fine particles X (fine) and so on. However, there are a few exceptions, such as high-quality surface O (image representation is perfect).
