Hard Anodizing of High Purity Alloys for the Semiconductor Industry

Hard Anodizing of High Purity AlloysFM Industries, Inc. has extensive experience handling projects for the semiconductor industry, this is why this client came to us for automated hard anodizing of high purity alloys. Our state-of-the-art hard anodizing process is fully automated and offers controls on over 28 operating parameters.

To begin the anodizing process, the surface was prepared to customer specifications. Sealing surfaces were polished to < 16 min Ra. To increase corrosion resistance, this 6000 series high purity alloy were anodized with a next generation multi-mixed acid electrolyte. Our automated process collects up to 60,000 data points per run in real time and we custom engineer to meet the specific needs of the customer.
