ã€China Aluminum Industry Network】 (1) The name of a product's brand name is represented by a code letter (prefix) or a combination of a chemical element symbol and an Arabic numeral. The number is used to indicate the principal component or sequence number; some brands have a suffix symbol to indicate Category, quality, characteristics, etc.
(2) The product code, represented by the combination of Hanyu Pinyin characters, chemical element symbols and Arabic numerals specified in the relevant standards.
The above general rules do not apply to four-character system grades used for deformed aluminum and aluminum alloys.
(3) The grades of this type of aluminum alloy product can adopt the character system representation method of GB/T16474-1996 standard.
In addition, the product's general name (such as aluminum), category, and product label (such as plates, tubes, tapes, foils, and wires) are still represented in Chinese characters.
The code of the status, processing method, and characteristics of the product shall be expressed in English letters specified in the relevant standards.
Precision alloy, is a kind of alloy owning special physical properties (such as magnetism, electrical, thermal and other properties).The vast majority of precision alloy is black metal based, only a few is based of nonferrous metals. It usually includes magnetic alloys, elastic alloys, expansion alloys, thermal bimetal, electrical alloy, hydrogen storage alloys, shape memory alloy, magnetostrictive alloy and etc.
In addition, in practical application some new type alloy are also considered to belonging into precision alloy, such as vibration damping alloy, stealth alloy, magnetic recording, superconducting alloys and microcrystalline amorphous alloy and etc.
