Description of business
KOUEI provides specialty metal materials, processed parts, design and manufacturing service for plant equipment.
Pure nickel, magnetic materials, low-expansion materials, and resistive materials are used in various forms in the battery, energy, and semiconductor industries, contributing to the development and production of products.

Processed products of iron-nickel alloys such as Permalloy, and of equivalent materials to Inconel and Hastelloy
Strip rolling and cladding

Plant equipment (auxiliary tilting furnace for low melting point metals)
Introduction of rolling process
Products and Technologies
Sales of pure nickel, nickel alloys and processed products
Various shapes are available from one piece

Shipment in the form of strip, round bar, billet, plate, pipe, etc.
●Possible as a comprehensive handling of nickel alloys
Materials stocked in abundance as strips, round bars, billets, plates, pipes, etc.:
Pure Nickel, Permalloy, Invar, Super Invar, Kovar, 42 Nickel, Nichrome, Constantan, Inconel (equivalent), Hastelloy (equivalent)
KOUEI cuts these materials and offers them in single pieces.

Processed products of iron-nickel alloys such as Permalloy, and of equivalent materials to Inconel and Hastelloy
●Both standard and custom specs are available
In addition to standard specifications, KOUEI coordinates processing methods such as lathe, milling, press work, heat treatment, plating, welding, etc., according to customer specifications and drawings. A wide range of quantities, from one to millions, can be accommodated as well as customer specifications.
KOUEI also promotes production rationalization to achieve short delivery time and cost reduction! For example, it is possible to produce plates from billets, pipes from billets and stamping instead of billet machining.
Precious metal clad and special rolled foil
From prototype to mass production
Cladding
●Precious and non-precious metal cladding
KOUEI manufactures clad materials in which precious metals are laminated to rolled copper products. The clad surfaces are heat-treated to form a strong alloy layer, resulting in a composite material with excellent adhesion and are mainly used as electrical contact material.
KOUEI offers cladding process to inlay different metals and overlaying process with two layers. In addition, KOUEI has in-house inspection equipment capable of verifying customer specifications to ensure thorough quality control.
Special rolled foil
●Manufacturing of rolled strips
KOUEI manufactures rolled strips in a wide range of steel grades, from pure nickel, nickel alloys, copper alloys and to aluminum alloys.
The 20 axis rolling mill at its own factory can produce rolled foil up to 20 μm. KOUEI can accommodate small batch production from prototype level.
Design and manufacture equipment for the plants using various alloys!
Various services such as material selection, strength calculation and drawing are available.
High pressure storage tank (ASME certification)
●Proven record
KOUEI has a proven track record in the design and manufacture of a wide range of plant equipment made primarily from heat and corrosion resistant materials such as nickel and titanium-based materials.
KOUEI responds to customer needs with a comprehensive manufacturing system that includes the procurement of materials necessary for production, as well as the design and manufacture of pressure vessels, electric furnaces and core tubes, and special specification welding equipment.

Piping 3D
●Research with 3D data
Even for products with complex shapes, 3D data is created in-house to allow customers to examine the shape of the product.
Data inspection not only solves 3D interference and layout problems at the design stage, but also enables strength issues, etc. to be checked in advance.
Quality can also be assured as the company has a variety of high function measuring instruments.
