The starting base for all the copper semi-finished products handled by Ramisa are copper cathodes, managed as the main international “commodity”.
Oxygen-free pure copper in the form of cathodes has a purity grade of 99.90% with the following maximum impurities: Bi max. 0.001%; Pb max. 0.005%; As max. 0.0015%.
There are then various types of remelted copper containing oxygen, for which it is necessary to request the analysis case by case.
Ramisa sas handles all the main copper semi-finished products.
Material traded in the exchange warehouses of the London Metal Exchange.
The Grade A copper cathodes traded on the exchange have the following characteristics:
Grade A copper cathodes with 99.90% purity as above
On the exchange, delivery is allowed only of the brands approved according to the list issued by the London Metal Exchange.
