2、e case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers pure aluminum metal (unal-loyed) for use in evaporation sour

3、ces and sputtering targets.This material is intended as a raw material for electronicapplications. The material is used as-supplied in some cases(for example, as e-beam evaporation sources). In other in-stances it may be remelted, alloyed, cast and processed by thepurchaser to make finished products

4、 (for example, sputteringtargets).1.2 This specification sets purity grade levels, physicalattributes, analytical methods, and packaging.1.3 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.2. Referenced Documents2.1 ASTM Standar

6、.1 Grades of aluminum are defined in Table 1. Impuritycontents are reported in parts per million by weight (wt ppm).4.2 Purity and total metallic impurity levels are based uponelements listed in Table 2.5. Ordering Information5.1 Orders for pure aluminum source material shall includethe following:5.

7、1.1 Grade (4.1),5.1.2 Configuration (8.1 and 8.2),5.1.3 Whether or not certification is required (12.1), and5.1.4 Whether or not a sample representative of the finishedproduct is required to be provided by the supplier to thepurchaser.6. Impurities6.1 The minimum suite of metallic impurity elements

8、to beanalyzed is defined in Table 2. Acceptable analysis methodsand detection limits are specified in Section 11. Elements notdetected will be counted and reported as present at thedetection limit. Additional elements may be analyzed andreported, as agreed upon between the supplier and the pur-chase

9、r, but these shall not be counted in defining the gradedesignation.6.2 Nonmetalic elements to be analyzed and reported are C,H, O, N, and S.6.3 Acceptable limits and analytical techniques for particu-lar elements in critical applications shall be as agreed uponbetween the supplier and the purchaser.

22、2.3 Impurity levels are to be reported in the certificate ofanalysis/compliance using actual analytical (not “typical”)results for the material lot. All impurity levels, except uraniumand thorium, shall be reported in wt. ppm. Uranium andthorium are ordinarily controlled at very low levels in thisma

23、terial and may be reported in parts per billion by weight (wt.ppb). Nondetected trace impurities shall be reported as presentat the mdl concentrations (6.1).13.
