Clear Hard Anodized Aluminum

In addition to the reasons above aluminum anodizing also offers some aesthetic benefits.

Clear hard anodized aluminum.

On some alloys the color of the aluminum after hardcoat anodizing will be gray bronze. Although anodizing aluminum creates a very hard surface you can actually damage it fairly easily if you use a harsh cleaner on it. The anodizing of aluminum is a popular process that improves the metal s durability resistance to corrosion and scratching. 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.

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. The same is true for anodized aluminum pots. The thicker the coating is the darker the color will also be. The actual appearance of clear anodized aluminum ranges from an extremely light shade of gray to a dark richer color.

Anodized aluminum is extremely durable as the anodizing process helps to harden and coat the metal. 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. Clear hard coat anodizing of a 6061 aluminum component for the medical industry. We offer two primary anodized aluminum anodic coating processes.

You need to use a gentle cleaner on them to keep them looking like new. 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. The part highlighted here is a 6061 aluminum clamping pulley. The color of the aluminum after being hard coat anodized depends on the alloy and the thickness of the coating.

Conventional low temperature 32 f hardcoating on normal aluminum alloys results in a dark bronze gray or black color. Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. For everyday aluminum surfaces use a gentle cleaner and try to keep abrasive sponges to a minimum. However hard anodizing is commonly performed clear or with a black dyed finish though some prefer the aluminum dyed different colors for aesthetic purposes.

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. 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.
