Type III Anodizing finishes are also known as hard coat finishes. These finishes are often used in a variety of industries, including military applications, electrical instruments, and kitchen products. The benefits offered by Type III make it one of the most highly requested industrial finishes.
What Is a Type III Anodizing Finish?
An anodizing finish places a final coat of protection onto a metal surface. This final coating is designed to increase durability and decrease the corrosive effects.
What Is the Difference Between Type III and Type II Anodizing Finishes?
Type III anodizing is a superior finish to Type II anodizing because it offers more advanced protection against corrosion. Products with Type III finishes are also more durable. Another key difference is that Type III finishes may utilize aluminum as a hard coating, which can be more appropriate for surfaces made of nonferrous metals, such as aluminum, nickel, tin, zinc and titanium.
Common Benefits of Type III
When you choose to have your products finished with type III coatings, they will have increased resistance to abrasion, wear and corrosion. They will also be easier to sterilize, which is especially important for industries that may experience potentially hazardous contaminations, such as the medical community. Customers often choose Type III due to the smooth appearance and improved aesthetic appeal.
Benefits Over Stainless Steel
Type III finishes typically are lighter than stainless steel. Stainless steel is also more expensive to produce or handle, and the machining for Type III finishes can be done twice as fast as the machining process for stainless steel.
