RIE offers in-house Anodizing to improve the durability, color stability, ease of maintenance, aesthetics, cost, and health and safety of aluminum products.

Anodizing is a crucial surface treatment process for metals like aluminum, known for its exceptional ability to enhance durability. By creating a protective oxide layer on the metal’s surface, anodizing provides resistance to corrosion, wear, and abrasion, significantly extending the lifespan of the material. This process also enhances the metal’s aesthetic appeal and improves its ability to withstand environmental factors, making it a valuable technique in various industries, from aerospace to consumer goods.

Anodizing is an electrolytic passivation process used to create a natural oxide layer for decorative, durable, corrosion resistant finishes for nonferrous metals. ALUMINUM is the only metal that is anodized.

​Anodizing is an electrolytic passivation process used to create a natural oxide layer for decorative, durable, corrosion resistant finishes for nonferrous metals.

​Aluminum oxide is applied by an electrochemical process that fully integrates with the aluminum substrate. This porous but highly stable finish is suitable for dyeing and sealing.


– Durability
– Color Stability
– Ease of maintenance
– Aesthetics
– Cost
– Health
– Safety


The hard anodized surface is hard and dense, it is often used as a wear surface. Lubricants, including fluorocarbons such as Teflon, can be impregnated into the surface to increase the lubricity without affecting the hardness.


– Improved wear resistance
– Non-conductive


Phosphoric acid anodizing is primarily used for bonding applications where environments contain high humidity.  Durable adhesive bonds between metal to metal, metal to composites can be obtained reliably only through proper selection and careful control of the materials used and the steps in the bonding process.

This coating has superior durability as compared to coatings of chromic or sulfuric acid, this is due to the film’s pores where whiskers or protrusions increases the bonding effectiveness. These properties allow for bonding of metallic and composite parts as well as pre-bond primer applications.

This as well as other anodic coatings provide predictable  performance, replicated and repeatable applications, and consistent test results.
