Aluminum is light, highly conductive, and has a beautiful silvery white color, but it is soft, easily corroded, has poor
coating adhesion and durability, scratches easily, and is prone to surface aging such as white rust and discoloration,
which limits its use as a metal material.
Anodic oxide coatings (ALUMITE) prevent scratches and wear by hardening the surface and increase corrosion resistance,
making aluminum suitable for a wide range of applications.
Conversion coatings (chromate) increase the corrosion protection of aluminum and also greatly improve the adhesion and
durability of the coating.
* If you have any issues with aluminum surface treatment, please do not hesitate to contact us. We will be happy to help you.
Our surface treatment methods allow aluminum to be used in a wide range of industries.
In addition to continuing to refine the technology and quality that we have developed in the aerospace industry, providing technology and reliable quality for a wide range of industries and developing technology to meet new needs.
Riken Alumite Industry has been certified by various aerospace manufacturers, such as Mitsubishi Heavy Industries Ltd.,
Kawasaki Heavy Industries, IHI Corporation, and IHI AEROSPACE Co., Ltd.
For certification status, we publish a "List of Special Process and Management Status" twice a year. If you would like a copy of the list sent to you, please contact our Sales Section.
We are also willing to handle oversized products, surface treatment for which it is difficult to find a suitable processor, seal treatment not listed in catalogs, etc.
If you have any issues with aluminum surface treatment, please do not hesitate to contact us.
Our anodized processing provides you with peace of mind.
If you want a perfect seal, we can provide you with a pressurized steam seal (available dimensions: 700 × 600 × 5,000 mm).
