This document does not apply to products with oxidation coatings produced by hard anodic oxidation process for technical purposes, products with oxidation coatings produced by coil anodic oxidation process and products worked after anodic oxidation. We have no amendments or corrections for this standard. Corrosion spots which were almost invisible before treatment may become more apparent.
Cross-Reference DIN 17611 Anodizing Standard
Additional rin for protecting semi-finished products and components during transport, in storage and during assembly shall be agreed between supplier and customer. Standards Subsctiption may be the perfect solution.
If the decorative appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection. The anodizing plant of Aluminium Din Emmi is one of the most up-to-date lines don this kind in Europe. Anodic oxidation generates an oxide coating on the surface of aluminium, which results in an increased resistance djn corrosion. This standard does not cover products with coatings produced by hard anodizing or batch or xin anodizing, or products worked after anodizing.
Anodizing creates an oxide coating on the surface of aluminium, protecting it more effectively from corrosion, and making durable decorative effects 117611 using a treatment as in table 1. By implementing etching-satinising process din surface gets tarnishing look, which varies according to type of aluminium alloy, state of surface, temperature and handling time.
It shall not exceed 20 S for uncoloured coatings.
Slight variations in shade due to differences in material and the production process are unavoidable. September 20, Post categories: The customer and supplier shall agree on the procedures to be used for anodizing and coloration, but details shall be left to the supplier. This standard is not applicable for products with oxide layers produced for technical purposes after hard anodising, products with oxide layers produced after coil anodising and for products diin have been shaped after anodic oxidation.
Grinding and polishing are followed by chemical or electrochemical burnishing, producing a mirror finish. You may delete a document from your Alert Profile at any time. If the document is revised or amended, you will be notified by email. Treatment E0 removes the natural oxide coating, leaving the metal largely intact. Your Alert Profile lists the documents that will be monitored.
All other methods involve considerable metal removal.

For dated references, subsequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. The vin of the coating on the visible surface shall be measured to an accuracy of 0,2 m three to five times at each of at least five points, 0,5 cm 2 in area, and the mean of the measurements for each point determined.
Electrochemical polishing Aluminium gains with it a shiny surface which is however very sensitive and therefore must ddin to the further treatment of anodizing as soon as possible. Other viewing distances shall be agreed between customer and supplier.
The surface appearance of products shall be in accordance with the technical delivery conditions given in the relevant standards 1711 clause 1.

Polishing Din is carried out automatically or manually.
