Anodising Grade Aluminium Sheet

Hard anodising gives best results on 6061 or 6082 alloys but 6000 and 7000 series aluminium is generally suitable for hard anodising.

Anodising grade aluminium sheet.

As mentioned above anodising is a reaction with the alloy surface you wish to coat and the resulting coating will depend on the quality and purity of the alloy used. Although aluminium itself is ideal for anodising different grades of aluminium react better to the process. 5000 series aluminium is the most commonly supplied anodised flat grade and supplied in sheet form. Anodising polishing powder coating.

Hard anodising is possible on 5000 series alloys but properties such as wear resistance will be compromised. Chemical composition of grade 1050. Anodizing is a metal coating process that increases the amount of aluminum oxide on the surface of an aluminum substrate thus potentially increasing its ability to withstand corrosion and alter its appearance. An electric current is then passed through it.

J57s is a 5000 series alloy manufactured by novelis. J57s anodising quality aluminium sheet. While many different aluminum alloys and grades can be anodized some are better suited to the process than others. 6063 is a very commonly anodised extrusion grade which offers a good consistent finish.

Grade 5251 is a medium strength alloy usually supplied in sheet form and is most commonly supplied in temper h22. In most cases it can be difficult to choose the correct aluminum grade for your intended application. Grade 1050h14 aluminium sheets are suitable for protective colour bright and hard anodising. Sapphire s process for anodising only lends itself to aluminium extrusion sheet and plate of certain alloys.

Grade 1050 h14 aluminium sheets are suitable for powder coating. It is suitable for decorative anodising and as a result is often used in architectural applications. J57s is a premium quality anodising sheet giving excellent anodising response with a highly consistent and repeatable finish. Aluminum is a common metal used for both industrial and non industrial applications.

1000 series are suitable for hard anodising but may exhibit some crazing which is an. Previously known as ns4 grade 5251 has many similar attributes to grade 1050 aluminium sheet and is probably the 2 nd most popular grade of aluminium sheet used in the uk today with grade 1050 being the most popular. Because a cathode is mounted on the inside of an anodizing tank the metal becomes an anode thus releasing oxygen ions that fuse with the surface aluminum atoms. Commonly used grade of aluminium in sheet and plate form.

Grade 1050 h14 aluminium sheets are suitable for polishing. Please contact us with your enquiries for 5251. If your project does not have any physical or structural demands and the aesthetics are not important then almost any aluminum grade will do the job.
