Aluminium anodizing in Eskilstuna

YTSAB Ytteknik in Eskilstuna handles enquiries for natural and coloured anodizing and hard anodizing of aluminium. Select the treatment according to the component's intended function.

Material and surface condition

Anodizing forms an oxide layer from the aluminium surface. Supply the full alloy and temper, the manufacturing route and information about welds or existing finishes. The incoming surface and material are part of the appearance assessment.

Natural finish and colour

The listed colour options include black, red, blue, purple, gold, champagne and green. Confirm the current option for the actual component and order. If several parts must match, identify the visible areas and agree a suitable reference rather than relying on a screen image alone.

Sealing and the next operation

Sealing changes the open pore structure of the anodic coating. Tell us if the component will subsequently be bonded or painted, so the full process can be considered. Specify appearance and functional requirements separately.

Dimensions, masking and contacts

Mark dimensions that apply after treatment, masking boundaries and permitted contact locations. Electrical contact areas and critical fits need explicit requirements. Include the applicable standard edition and the required inspection scope.

Trials and delivery

For a new article, define what a trial should demonstrate and who approves it. Confirm delivery to YTSAB Ytteknik AB, Pressargatan 10, 632 29 Eskilstuna, before dispatch.
