Foreword
Instead of the standard YS/T 275-2000 "high purity aluminum."
This standard is a revision of YS/T 275-2000 "high purity" of. Compared with YS/T 275-2000, the main changes are as follows.
--- Of Si, Ti, Zn impurity content has been revised;
--- Of grades that method has been modified;
--- On the surface quality it was clearly defined;
--- Product sampling were clearly defined;
--- The product packaging clearly defined.
This standard by the National Standardization Technical Committee of non-ferrous metals and centralized.
This standard is drafted by. Aluminum Corporation of China Guizhou Branch, public and Xinjiang Company.
The main drafters of this standard. high Shulan, who Ping, Cui Jian, Liu Gang, Shang Guangyu, Liu Jie, Di Xinsheng, He Xinguang, SONG.
This standard replaces the standards previously issued as follows.
--- GB/T 8179-1987;
--- YS/T 275-1994, YS/T 275-2000.
High purity aluminum
1 Scope
This standard specifies the high purity requirements, test methods, inspection rules and signs, packaging, transportation, storage, purchase orders (or contract) content.
This standard applies to 99.99% of aluminum as raw materials, solidification purification method such as the production of high purity aluminum.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research
Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

YS/T 244.1 ~ 244.9 Chemical analysis methods of high purity aluminum
3 Requirements
3.1 Categories
High purity aluminum into Al-5N, Al-5N5 two grades.
3.2 Chemical composition
High purity chemical composition shall comply with the requirements in Table 1.
Table 1

Chemical composition (mass fraction) /%
Al
not less than
Impurity content (× 10-4), not more than
Cu Si Fe Ti Zn Pb Ga Cd Ag In Cu + Si + Fe + Ti + Zn + Ga sum

Note 1. The aluminum content was 100% and the mass fraction of the table is equal to or greater than 0.10 × 10-4% of the difference between the sum of impurities.
Note 2. The analysis determined using numerical rounding comparative method, numerical rounding rules in accordance with relevant provisions of GB/T 8170 will be. Rounding digit pole and listed in the table
Limit the number of bits the same.
Note 3. impurity elements As, Hg, Cr, or other impurities demand side, if required, by agreement between the.
Note 4. For party have special requirements, both parties agree otherwise, but the content is less than 0.10 × 10-4% of impurities, not included in the sum of impurities.
3.3 surface quality
3.3.1 high purity aluminum products for the silver-white, bright surface with clear crystalline stripes.
3.3.2 high purity aluminum surface may not have visible inclusions.
3.3.3 high purity aluminum surface allows chipping process, but the process should not affect the chipping defect users.
3.4 Delivery shapes and sizes
High purity aluminum supplier shapes and sizes to comply with Table 2. For parties have special requirements, and both parties agree otherwise in the contract
