Copper weight calculation method
The regions are Japan, the United States, Hong Kong, Belgium, Australia and Germany. The types of imported scrap copper are mainly scrap copper, scrap wires, cables and a large number of scrap motors with low copper content. Domestic imports include Copper rod W=0.00698×diameter square
Brass rod W=0.00668×diameter square
Aluminum rod W=0.0022×diameter square
Square copper rod W=0.0089×side width square
Square brass rod W=0.0085×side width square
Hexagonal copper rod W=0.0077×distance from opposite sides square
Hexagonal brass rod W=0.00736×distance from opposite sides square
Copper plate W=0.0089×thickness×width
Brass plate W=0.0085×thickness×width
Aluminum plate (pure aluminum) W=0.00271×thickness×width
Pattern aluminum plate (pure aluminum) W=0.00271×thickness×width×length+(width×length×0.6)
Copper tube W=0.028×wall thickness×(outer diameter-wall thickness)
Brass tube W=0.0267×wall thickness×(outer diameter-wall thickness)
Aluminum tube W=0.00879×wall thickness×(outer diameter-wall thickness)
Copper busbar W=0.0089×width×thickness
Aluminum busbar W=0.0027×width×thickness
Note: The unit of W is kg/m, and other units are mm.
With the continuous standardization and development of the domestic recycling trading market, the rapid development and renewal of industries such as electricity, construction, and transportation, the domestic recycling and utilization of recycled copper has gradually increased, and the development of production, trade and finance has been integrated
The latest drilling results of projects such as Xinfa Copper Mine, Ecuador Condor Copper Mine, and Ecuador Condor Copper Mine have been obtained.
