Anodizing Aluminum Cylinders: An Economical Approach to Resolving Surface Finishing Challenges
To permit the use of aluminum instead of other, heavier metals in industrial applications, many cylinders are anodized to create an extremely hard surface that is wear-resistant, corrosion resistant, non-conductive and lubricious. Because anodized surfaces are porous, they also improve adhesion of coatings as well as accept a variety of dyes for coloring.
Given the myriad of benefits, anodizing is popular for a variety of cylindrical items including lift mechanisms for chairs, lift cylinders for hatchbacks, shock absorbers and forks for bicycles, fuel pumps, water pumps, pneumatic and hydraulic cylinders, spool valves, valve stems and valve bodies.
