Copper round bar

Our copper round bars are manufactured from tough pitch copper and oxygen-free copper.
Some products are finished by cold drawing after hot rolling or hot extrusion, while others are finished by lathe processing after hot forging.
We have a wide manufacturing range and excellent dimensional accuracy.
Types
・Tough pitch copper rod (CuB)
It has excellent electrical and thermal conductivity, ductility, corrosion resistance, and weather resistance, and is used for electrical components and chemical industry parts.
