Yagimaito Processing (In-House Development)

Yagimaito processing adds a thickness of about 1μm on the outermost surface of the anodized aluminum film, to ensure maximum corrosion resistance
Patent Number: 3803353

Alkaline corrosion resistance of Yagimaito is about 5 times more than before!
Alkali resistance test by electromotive force

※1: Measurement errors vary with changes in humidity

Compared to conventional products the etching depth of Yagimaito at an acceleration voltage of 1.5KV is reduced to 10.6%, declining even further to 12.0% at 2.0KV, and in the case of 2.5KV it was reduced by 21.2%. Therefore, Yagimaito is more plasma resistant than conventional products.
