Introducing the little-known "secret" of copper prices!

The price of copper is determined on the London Metal Exchange (LME). Why London, and why is it traded in dollars instead of pounds? We will explain this clearly through four pages of illustrations, covering the history of metal trading in 19th century Britain and the reasons for dollar-denominated trading specific to international commodities like copper. Ishigaki Shoten has a wide range of processing achievements in copper busbar products for transformer manufacturers and panel manufacturers in the Tokai region, with thicknesses ranging from 3mm to 20mm, processing as much as 150 tons of copper annually as a specialized copper processor. With a consistent production system from order to processing, plating, and delivery, we can respond quickly with drawings and order forms! Hand-drawn designs are acceptable! We truly accept orders from just one piece! Urgent orders are welcome! Please feel free to consult with us!
