Aluminium, not alloyed:
Metal containing by weight at least 99 % of aluminium, provided that the content by weight of any other element does not exceed the limit specified in the following table:
a Other elements are, for example, Cr, Cu, Mg, Mn, Ni, Zn. | |
b Copper is permitted in a proportion greater than 0,1 % but not more than 0,2 %, provided that neither the chromium nor manganese content exceeds 0,05 %. | |
Element | Limiting content % by weight |
---|---|
Fe + Si (iron plus silicon) | 1 |
Other elementsa, each | 0,1b |
Aluminium alloys:
Metallic substances in which aluminium predominates by weight over each of the other elements, provided that:
the content by weight of at least one of the other elements or of iron plus silicon taken together is greater than the limit specified in the foregoing table; or
the total content by weight of such other elements exceeds 1 %.
