Anodising Grade Aluminium Sheet

Chemical composition of grade 1050.

Anodising grade aluminium sheet.

J57s anodising quality aluminium sheet. 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. Sapphire s process for anodising only lends itself to aluminium extrusion sheet and plate of certain alloys. In most cases it can be difficult to choose the correct aluminum grade for your intended application.

Please contact us with your enquiries for 5251. Aluminum is a common metal used for both industrial and non industrial applications. An electric current is then passed through it. Although aluminium itself is ideal for anodising different grades of aluminium react better to the process.

While many different aluminum alloys and grades can be anodized some are better suited to the process than others. Hard anodising gives best results on 6061 or 6082 alloys but 6000 and 7000 series aluminium is generally suitable for hard anodising. Commonly used grade of aluminium in sheet and plate form. 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.

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. 5000 series aluminium is the most commonly supplied anodised flat grade and supplied in sheet form. The aluminum or other suitable metal such as zinc or magnesium is immersed in an acid electrolyte bath. J57s is a premium quality anodising sheet giving excellent anodising response with a highly consistent and repeatable finish.

It is suitable for decorative anodising and as a result is often used in architectural applications. Hard anodising is possible on 5000 series alloys but properties such as wear resistance will be compromised. 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. J57s is a 5000 series alloy manufactured by novelis.

Grade 1050 h14 aluminium sheets are suitable for powder coating. 6063 is a very commonly anodised extrusion grade which offers a good consistent finish. Grade 1050h14 aluminium sheets are suitable for protective colour bright and hard anodising. Aalco stock of range j57s anodising quality aluminium sheet.
