Used as an electrode material for aluminum electrolytic capacitors. Our proprietary refining technology and integrated production system, the only one of its kind in Japan, has enabled us to achieve high performance and quality, and we have the largest market share in the world.
A revolutionary aluminium alloy sheet with high strength comparable to 6061 structural material, and with thermal and electrical conductivity comparable to pure aluminum. It has good anodizing properties, and a color tone similar to 6063 extruded material.
We manufacture various products, such as aluminium sheets and foils with purities ranging from 99.9％～99.99％. We can provide products of any purity and size according to your requirements, in small lots.
An aluminum alloy sheet with a low expansion coefficient that can resist solder cracks that occur in environments with repeated temperature changes between high and low temperatures.
A special product made of 99.99% high-purity aluminum. It is used in the electronic components field, such as for sputtering targets and evaporation materials, and in the superconducting materials field.
Superior in brilliance to 1070 aluminium alloy, this series is used for cosmetic caps and fountain pen cases. For the shape, you can choose from either square sheets or coils.
Anodization with masking is also available for 1100-H14 fixed-size sheets for construction use.
We offer PP caps for medicinal drinks, rinpul caps for alcoholic beverages, and various alloy sheets for moisturizing cream containers.
Since 1933 when we began operating an integrated manufacturing plant in Sakai producing everything from aluminium sheets to containers, we have been developing technologies and products with the aim of becoming the number one company in the industry, while continuing integrated production from materials to processing.
Our products are produced through advanced production technologies with thorough quality control during each process, from melting and casting to rolling and finishing of sheet and foil products. They are used in various fields and contribute to the development of industry.
In particular, our aluminium foil for electrolytic capacitors, which utilizes our proprietary aluminium refining technology known as the "Cojunal Method," continues to lead the evolution of products and technologies as the industry's front-runner, backed by our high competitiveness in quality, cost, delivery, compatibility, and development.
