Scope*1.1 This is a classification of the various types of coppercurrently available in refinery shapes and wrought products incommercial quantities. It is not a specification for the va
3、rioustypes of copper.1.2 In this classification, use is made of the standard copperdesignations in use by the copper industry.1.3 Although this classification includes certain UNS des-ignations as described in Practice E527, these designations arefor cross-reference only and are not requirements. Th

The total copper plus specific permittedelements is usually specified
6、 as 99.85 % or more. These intentionallypermitted elements normally include, but are not limited to, arsenic,cadmium, chromium, lead, magnesium, silver, sulfur, tellurium, tin, zinc,and zirconium, plus deoxidizers, up to specific levels adopted by theInternational Standards Organization.1.5 UnitsThe

Basis of Classification5.1 Table 1 lists the standard designations, and the refineryshapes and fabricators products currently produced. The listedcoppers are not necessarily available in the complete range ofsizes in the form show
