Since its founding, KOUEI has been supplying high temperature / corrosion resistant alloys, magnetic materials, low-expansion alloys (Kovar, Invar), electronic metal parts and various special alloys to many different fields such as petrochemical, industrial machine, heat exchanger, electronics industry, marine development, electric power and aerospace industry and other industries.
At first, we have delivered raw materials in a shape of wire, bar, sheet, pipe and strip, and gradually as responding to various demands, we have been supplying processed parts.
Today, we also design and manufacture various industrial machineries and plant equipment.

Regarding to processing way for special metal alloys, there are variety of problems like poor machinability, difficult plasticity, specific heat treatment specification and special welding techniques.
We have improved and researched these processing techniques and application of the materials for a long time. And more, we have established network of cooperative factories.
In 2009, we opened a factory for rolling and heat treatment of strips, and for development of clad metals.
The factory can answer to customer’s requests such as small amount of custom-made products or from trial production to mass production.
In the field of advanced technology development, special alloys are playing an important role increasingly large every year.
KOUEI will contribute to development of technology through supplying highly- functional materials.

For nickel alloys and low-expansion alloys— ask KOUEI.

As the comprehensive manufacturer of nickel alloys, KOUEI stocks variety of nickel alloys and low-expansion alloys such as Kovar, Invar, Super invar. It is our feature that not only selling metal materials, we can also accomplish total management consistently from design, processing to assembly by ourselves.
