Type 3 (III) Hard Coat Anodizing

Type 3 (III) Hard Coat Anodizing on a gun part

 

 

 

 

Type 3 hard coat anodizing, also known as hard coat anodizing, is similar to Type 2. However, the typical coating thickness is around .002 of which 50% is penetration and 50% buildup per surface. This is the most durable anodize finish and has wear characteristics comparable to electroless nickel and hard chrome. INCERTEC’s Type 3 hard coat anodizing services are used for applications that need to hold up to heavy usage and extreme conditions without needing to be replaced.

Why Type 3 Anodizing?

Certain industries demand a harder coating for their products to minimize chipping, breaking, or corroding under harsh conditions. That’s where INCERTEC’s Type 3 hard coat anodizing services come in. We provide Teflon and PTFE hard coat anodizing for the following industries:

Type 3 anodizing is a great candidate for high-usage parts and products that will require ultimate durability and corrosion resistance. INCERTEC has years of experience coating parts such as engine pistons, hunting bows, gun parts, and even cookware to withstand extreme temperatures and conditions.

With a hardness of 60-70 on the Rockwell C scale, Type 3 anodizing proves to be a superior coating when compared to chrome, ceramic or nickel. The end result is a finish that’s harder than tool steel. While this type of coating is denser than Type 2, it won’t add weight to a part, making it a great option for industries like aerospace where weight is a critical factor.
