Case Study of Solutions and Cost Reduction (VA Proposal) Case 3

We would like to introduce a case where we successfully reduced costs through a VA proposal for our client.

Case 3: Trivalent Chromium Conversion Treatment for Aluminum Die Casting Material (Alozin Alternative) ■ Automotive Parts Die Casting Company N As part of a cost reduction plan for products that were anodized for corrosion resistance (rust prevention) on aluminum die casting materials, we proposed a trivalent chromium conversion treatment (Alozin alternative) for aluminum die casting. Since the condition was to clear the JIS neutral salt spray test with a rating number (RN) of 9.5 for 72 hours, we conducted a trial production for evaluation. It cleared without any issues, leading to mass production due to the specification change.

What is trivalent chromium chemical treatment?

A detailed explanation of trivalent chromium chemical treatment!

Conversion treatment refers to a process in which metals are immersed in a conversion treatment solution to create a firmly adhering, insoluble product on the metal surface. By utilizing the physical or chemical properties of this product, it is used as a coating base with excellent corrosion resistance and adhesion. 【Effects and Features of Trivalent Chromium Conversion Treatment】 ■ Improved corrosion resistance of aluminum alloys ■ Enhanced rust prevention effect ■ Improved adhesion for coating base purposes ■ Suppresses the decrease in corrosion resistance during heating, which is a disadvantage of chromate treatment ■ The coating is thin and does not cause dimensional changes ■ Complies with RoHS directive (no hexavalent chromium content) *For more details, please refer to the PDF document or feel free to contact us.
