Black Anodized Aluminum Finish

The items below are designed to assist you in your choice of architectural aluminum finishes.

Black anodized aluminum finish.

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. It protects against corrosion enhances aesthetic qualities resists scratching and is one of the most durable surface finishes available. Clear and black finishes are also known as decorative anodize. Anodizing is a method for changing the surface chemistry of metals and other substrates.

It is strong and corrosion resistant plus it s easy to machine and weld. In addition to the reasons above aluminum anodizing also offers some aesthetic benefits. Aluminum component parts that have been welded will show some discoloration on the welds after it is anodized even if the component has been. Prior to the development of this new blackening process black anodizing had been the only viable blackening option for manufacturers of aluminum components.

The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell anodizing increases resistance to corrosion and wear and provides better adhesion for paint primers and glues than bare metal does. Anodizing can be done on a range of materials but today let s look at aluminum. Learn more about our selection of anodized aluminum finishes below. There are some who maintain that it can be applied over smooth anodized surfaces as well.

Anodized aluminum finishes can give your extrusions a chic professional look not only improving the aesthetic but also the performance. A common application of this type of finish is fluoropolymer coated hard anodized aluminum cookware.

The most widely used aluminum 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. You will have to be the judge as to whether or not this type of anodic coating will work for your particular application. The market for architectural aluminum products demands a greater variety of finish types and colors than ever before. While the anodized finish is extremely durable the process is so complex that only those who specialize in it can operate it properly and consistently.

Anodizing creates a non conductive protective coating. To achieve maximum corrosion resistance anodized particles are boiled in a solution of nickel acetate which effectively seals the component.
