Anodization is the process used to give the final finish to aluminum to improve corrosion resistance.
This process is often used for the components of computer equipment made by Apple and other
companies, and for precision devices such as cameras. iPads are used in various locations where the
environmental conditions are severe, so they require high levels of corrosion resistance, abrasion
resistance, hardness, and electrical insulation. Aluminum anodizing is an effective way of protecting
these products. We are not a precision device manufacturer, but, since anodizing can augment
corrosion resistance and strength as compared to the aluminum which is usually used, we want to
make furniture using anodized dyeing and finishing of aluminum, a technique that grew out of the
original process of anodizing aluminum. The anodized dyeing and finishing of aluminum means that
the surface is not painted, but, just like indigo dyeing, the aluminum itself is dyed through a sealing
process in which dye is poured into pores on the porous layer generated from the anodizing process,
and then the pores are sealed. ｑThis dyeing and finishing adds a touch of deepness to the aluminum
and makes possible the creation of a range of colors and tones depending on the anodizing process,
the density of the dye, and the duration of dye application. Aluminum anodizing is a technique
designed to improve the corrosion resistance of aluminum through the following processes:
i. Electrolyze aluminum as the anode in a treatment bath containing dilute sulfuric acid or oxalic acid.
ii. The aluminum is oxidized electrochemically and a film of the oxidized aluminum is formed.
iii. The film is partially dissolved and honeycomb-like pores are created, forming a porous layer of
iv. The pores are sealed using boiling water or steam under pressure.
Color anodizing involves the application of color through the pores absorbing the dye utilizing the
characteristics of the porous layer. Due to its ability to preserve fine colors for years and improve
corrosion resistance, this technique enhances beauty and functionality.
This processing technique originated in Japan and was invented by researchers from the Institute of
Physical and Chemical Research in 1929 and has been used for about 70 years. For these products,
we created a design that was simple overall and adopted a simple structure by fastening solid
aluminum plates for the top and bottom, and a solid aluminum pole as a prop, and assembled using
joint parts and bolts. We gave the table the name “Blue in Green”. We felt that the combination
of blue and green colors was especially well suited to the anodized aluminum material. However,
during the trial manufacturing, we have found that yellow, purple, and pink also go well with
aluminum. Therefore, we have created products in nine colors.
“Blue in Green” is famous as a piece of music by Miles Davis, but in fact, the piece is said to be by
Bill Evans, a pianist. It is a masterpiece of jazz filled with a beautiful, tasteful melody from the intro
to the end.
