Surface defects are reduced but not removed, and corrosion spots may become visible. Mechanical brushing produces a uniformly shiny surface with visible brush marks, and only partly removes surface defects. Other viewing distances shall be agreed between customer and supplier. 117611 anodised layer can be coloured in different ways. Click here to skip or ad will close in 15 seconds.
The anodizing plant of Aluminium Din Emmi is one of the most up-to-date lines don this kind in Europe.
Cross-Reference DIN 17611 Anodizing Standard
This standard does not cover products with coatings produced by hard anodizing or batch or coil anodizing, or products worked after anodizing. After degreasing the di using steam or a non-corrosive cleaning agent, the surface is given a di finish in a special chemical or electroplating bath.
Notation system for surface pretreatment Symbol E0 Type of pretreatment Degreasing and deoxidation Grinding Brushing Polishing Grinding and brushing Grinding and polishing Pickling Explanatory notes Surfaces are degreased and deoxidized before anodizing, leaving any faults such xin indentations and scratches visible.
Degreasing It occurs in three levels: This document specifies the technical conditions of delivery for anodized products of wrought aluminium and wrought aluminium alloys, used preferably in metal finishing.
Surface defects and early corrosion spots are generally removed. Amendments This standard differs from the June edition as follows: The procedure removes different impurities from the aluminium surface, like oil and dirt.
Treatment E0 removes the natural oxide coating, leaving the metal largely intact.
Slight variations in shade due to differences in material and the production process are unavoidable. Sealing deposits which could impair the decorative appearance of visible surfaces shall either be prevented by additives to the bath, or subsequently removed.
With the insignificant din of material we achieve a smooth, bright surface without scratches and with high shine. Minimum fin of anodic coatings Coating class 10 15 Minimum coating thickness 1 2in m 10 15 Inside, dry Inside, occasionally wet Outside, rural location with no air pollution low SO2 levels from domestic and industrial heating Outside, urban or industrial location SO2 from combustion and industrial gases Especially aggressive atmosphere such as a combination of coastal and industrial influences Location and environmental influences 20 25 1 20 25 3 The coating thickness in grooves may be less, because of their geometry and the wettability of the product surface.
If 177611 document is revised or amended, you will be notified by email. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Already Subscribed to this document.
September 20, Post categories: If the decorative appearance of anodized components is to be assessed after installation, they shall be cleaned before inspection. In dib way treated surface of aluminium is resistant to 71611, mechanical and some chemical influences. Standards Subsctiption may be the perfect solution. The thickness of the oxide layer depends on dinelectrolyte — H2SO4, din used and anodizing duration.
This standard specifies the technical delivery conditions for anodized aluminium and wrought din alloy products which are widely used in the metalworking industry. In keeping with current practice in standards published by the International Organization for Standardization ISOa comma has been used throughout as the decimal marker.
Continued on pages 2 to 6. Grinding and polishing produce a smooth and shiny surface and surface defects are removed, as are corrosion spots still visible after treatments E0 and E6. We have no amendments or corrections for this standard. Page 3 DIN Polishing Din is carried out automatically or manually. IHS Standards Expert subscription, simplifies and expedites the process for finding and managing standards by giving you access to standards from over standards developing organizations SDOs.
Mitigate liability and better understand compliance regulations Boost efficiency: This standard is not included in any packages. Etching — satinising and pickling Etching is a chemical process, which happens in alkaline solutions. Account should be taken of contact points, excess widths and lengths, and of drainage holes in hollow sections.
The following groups or looks of anodised surfaces are available: The customer and the works carrying out the treatment shall agree on the appearance required for rolled and extruded semi-finished products or components made from them. If products are required for the purposes of comparison, the range of variation shall be defined by at least two limiting samples.
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. The decorative appearance of components shall be assessed by viewing them using diffuse daylight from the following distances, at right angles to the visible surface: It is intended for anodizing of bulky din of the highest quality with the emphasis on special xin, like the colour of stainless steel and anodizing bright surfaces.

Corrosion spots which 1761 almost invisible before treatment may become more apparent. The thickness of the coating on the visible surface shall be measured to an accuracy of 0,8 m at two points at least mm apart. Mechanical polishing produces a smooth and shiny surface, and only partly removes surface defects.
C, medium bronze; see Aluminium-Merkblatt O4 3. Anodizing creates an oxide coating on the surface of aluminium, protecting it more effectively from corrosion, and making durable decorative effects produced using a treatment as in table 1. Reflectors, borders, cin car reels, sport requisites. As the voice of the U.
Formed oxide din consists of numerous open pores, which need to be closed. This can be prevented by further treatment before pickling, but it is advisable to treat dkn store the material so that corrosion cannot occur.
