Clear Hard Anodized Aluminum

Conventional low temperature 32 f hardcoating on normal aluminum alloys results in a dark bronze gray or black color.

Clear hard anodized aluminum.

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. 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. Although anodizing aluminum creates a very hard surface you can actually damage it fairly easily if you use a harsh cleaner on it.

The same is true for anodized aluminum pots. 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. 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. The part highlighted here is a 6061 aluminum clamping pulley.

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. 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 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.

Clear hard coat anodizing of a 6061 aluminum component for the medical industry. The color of the aluminum after being hard coat anodized depends on the alloy and the thickness of the coating. For everyday aluminum surfaces use a gentle cleaner and try to keep abrasive sponges to a minimum. Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

You need to use a gentle cleaner on them to keep them looking like new. The actual appearance of clear anodized aluminum ranges from an extremely light shade of gray to a dark richer color. 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. This process helps to create a weather resistant tarnish resistant surface that can remain.

The thicker the coating is the darker the color will also be. On some alloys the color of the aluminum after hardcoat anodizing will be gray bronze.
