High-purity Metals
Our products in this category include High-purity Gallium, high-purity indium, high-purity antimony, high-purity copper, high-
purity zinc, high-purity magnesium, manganese and gallium oxide.
These products have been refined to a purity of 99.9999% or higher (6N).
In particular, we also hold the No. 1 share in sales of High-purity Gallium in the world market.
We are also recycling various types of metals.
