Clear Hard Anodized Aluminum

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

Clear hard anodized aluminum.

The color of the aluminum after being hard coat anodized depends on the alloy and the thickness of the coating. Clear hard coat anodizing of a 6061 aluminum component for the medical industry. The thicker the coating is the darker the color will also be. However hard anodizing is commonly performed clear or with a black dyed finish though some prefer the aluminum dyed different colors for aesthetic purposes.

The clear anodized aluminum process involves washing the metal with specific chemicals for the process. The anodizing of aluminum is a popular process that improves the metal s durability resistance to corrosion and scratching. We offer two primary anodized aluminum anodic coating processes. He has never seen a clear anodized coating which could meet the minimum requirements for thickness 2 0 mils 20 and wear resistance twi 1 5 of mil spec hardcoating.

On some alloys the color of the aluminum after hardcoat anodizing will be gray bronze. Sulfuric anodizing type ii class i and modified hardcoat anodizing also known as hard coating each having unique properties and benefits selecting the correct anodizing process depends on the end use application and specific properties needed of the part. Clear hard coat anodizing click on thumbnail to enlarge our capabilities at automatic anodizing include the ability to perform hard coat anodizing in accordance with mil a 8625 type iii specifications. Aluminum hard anodizing also known as mil a 8625 type iii or engineered anodizing is similar to standard anodizing in that both are controlled electrochemical processes.

Techmetals has over 50 years experience in titanium and aluminum anodize assisting a variety of industries like the medical aerospace and automotive fields for instance. 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. Anodized aluminum is extremely durable as the anodizing process helps to harden and coat the metal. The part highlighted here is a 6061 aluminum clamping pulley.

The actual appearance of clear anodized aluminum ranges from an extremely light shade of gray to a dark richer color. The same is true for anodized aluminum pots. Conventional low temperature 32 f hardcoating on normal aluminum alloys results in a dark bronze gray or black color. This process helps to create a weather resistant tarnish resistant surface that can remain.

In addition to the reasons above aluminum anodizing also offers some aesthetic benefits. Many of the 6xxx series of aluminum will take on a deep gray black color while most 7xxx and 2xxx series will appear a more bronze gray color.
