GB/T3190--1996
This standard is a revision of GB3190--82 based on the newly formulated GB/T16474-1996 "Methods for indicating grades of wrought aluminum and aluminum alloys" and the development of domestic production and use of wrought aluminum alloys in the past decade. This standard changes the original standard's grade indication method. All alloys with the same chemical composition as the alloys named by the International Grade Registration Agreement Organization for Wrought Aluminum and Aluminum Alloys (hereinafter referred to as the International Grade Registration Organization) directly use the international four-digit system grade: other alloys except the above alloys use the four-character system grade specified in GB/T16474--1996. In this way, the grade indication method of wrought aluminum and aluminum alloys in my country is basically consistent with the more common method in the world. This standard includes 143 grades, 62 grades in GB3190--82 are retained (including six industrial pure aluminum grades L1, L2, 1.3, 1.4, 1.5 and L5-1 replaced by grades with similar composition), and 81 new grades are added. LT62 and LT75 in GB3190-82 are no longer used, LF11 is merged into LF5, LQ1 and LQ2 for pin connection are bimetallic, directly included in the pin connection plate standard, and no longer included in this standard. Among the newly added grades, some have been developed and finalized in China, such as 1.Y20, IY19, LF15, LF16, I.C15, I.C19 and LC52 in the national military standard; most of the grades are alloys directly introduced from the international grade registration organization. When these alloys are used for important purposes, they must be developed and identified before they can be officially produced and used. The following three standards are closely related and should be used simultaneously: GB/T3190-1996 Chemical composition of wrought aluminum and aluminum alloys GB/T16474-1996 Method of indicating grades of wrought aluminum and aluminum alloys GB/T16475-1996 State codes of wrought aluminum and aluminum alloys This standard replaces GB3190-82 from the date of its entry into force. The old grades listed in the "Remarks" column of Table 1 of this standard may continue to be used during the transition period, but the new technical documents should use the new grades. Natural transition, no limit on the transition time. Appendix A of this standard is a reminder appendix.
This standard is proposed by China Nonferrous Metals Industry Corporation. The Standard Metrology Institute of China Nonferrous Metals Industry Corporation is responsible for this standard. This standard was drafted by Northeast Light Alloy Jiahui Factory. The main drafters of this standard are: Zou Zhenchu, Xiao Yaqing, Huang Yongqing, Wu Xinfeng, Liu Yuanchao and Ge Lixin.3

GB/T164?4-1996 Deformed aluminum and aluminum alloy grade indication method 3 Requirements
3.1 Chemical composition
The chemical composition of deformed aluminum and aluminum alloys shall comply with the provisions of Table 1. 3.2 Sampling
3.2.1 Production shall be carried out according to For each melting, take a sample for chemical composition analysis from the melt. For continuous casting, at least one sample should be taken per shift. 3.2.2 The user shall take a sample for chemical composition analysis from the processed product. When sampling, the sample should be as representative as possible. The sample taken should be cleaned to remove the oxide scale, coating, dirt, oil and lubricating oil, etc., and the composition of the sample should not be changed due to corrosion, oxidation or contamination. 3.2.3 The sample should be taken in duplicate, one for analysis and one for reference. The shelf life of the sample for reference is: no less than half a year for pure aluminum and no less than 1 year for aluminum alloy.
3.3 Composition analysis Analysis
3.3.1 During routine analysis, only the elements with numerical values ​​specified in Table 1 shall be analyzed. Aluminum shall not be analyzed unless otherwise specified. If it is suspected that other elements exceed the specified values, further analysis shall be conducted. 3.3.2 Routine analysis may be conducted using methods specified in national standards or other accurate and reliable methods. In case of dispute, arbitration analysis shall be conducted using GB/T6987 or other methods agreed upon by both parties. 3.3.3 If the results of the first analysis are unqualified, a second analysis is allowed, and the results of the second analysis shall be used as the basis for the manufacturer's factory delivery and acceptance.

GB/T3190--1996
4.1 When the aluminum content is greater than or equal to 99.00% but less than 99.90%, it shall be determined by calculation, that is, the difference between 100.00% and the sum of all elements not less than 0.010%. Before summing, the value of each element shall be expressed to 0.0×%. 4.2 When the aluminum content is greater than 99.90% and less than or equal to 99.99%, it should be determined by calculation, that is, the difference between 100.00% and the sum of all elements with a content of not less than 0.0010%. Before summing, the value of each element should be expressed to 0.0××%, and after summing, the sum should be rounded to 0.0x%
4.3 In Table 1, those with upper and lower limits are alloying elements; those with a single value, aluminum is the lowest limit, and other impurity elements are the highest limit. The "other" column refers to metal elements that are not listed or have no specified values. For some elements not listed in the header, when there are limit requirements, their specific provisions are listed in the blank column.
4.4 The number of digits of the element content given in the chemical composition analysis report should be consistent with the number of digits of the corresponding grade specified in Table 1. 4.5 The method of numerical rounding shall be carried out in accordance with the provisions of GB/T8170. 4.6 The terms of this standard conform to the provisions of GB/T8005. 4.7 The designations of grades in this standard conform to the provisions of GB/T16474. 4.8 For the comparison of the old and new grades, see Appendix A (suggestive appendix).
