Key Strengths: There are a number of key features that make Sulphuric Anodising key for particular applications:
Limitations: There are a number of limitations associated with Sulphuric Anodising:
Applications: General applications.
Tanks: We offer tank sizes up to 13' x 5' x 4'.
Thickness: Standard coating thickness is 5-7µm.
Finish: A range of colour dyes are available.
Jigging: Correct jigging is essential to the resulting finish, and good jig points are required, a consideration that should be made at the design stage of a component. The use of loose, sliding or intermittent contacts will result in an unsatisfactory connection and give rise to faults such as thin coatings, burning at the contact points or even failure to obtain an anodised coating.
