United States Copper Metal and Scrap Use and Trade Patterns, 1995–2014.

摘要

Copper-containing products include copper metal, copper alloys, and copper chemicals. All of these are manufactured in the United States from primary raw materials supplemented by significant quantities of secondary materials (recycled scrap). Throughout the study period, 1995?2014, the flows of copper-containing materials needed for the manufacture of useful copper-containing products changed. Trends for these changes are reported here. This report considers changes to the copper and copper scrap industries of the United States.
