Applicability and limitations
Mass fraction wt%; GB/T5231—2012, Table 3, row 43, designation T49230. Zn is the balance; A dash means unspecified; it is not entered as zero; Tabulated total impurities ≤0.5%. Table 3, note c: total impurities are the sum of measured contents of the impurity elements listed in the table; The principal alloying constituent Bi must not be counted as an impurity.
