Passivation

Enhance your metal components' lifespan and corrosion resistance with C&H Machine’s expert passivation services. Adhering to industry standards AMS2700, AMS-QQ-P-35, and MIL-DTL-5002, our precise treatment removes impurities and forms a protective layer, ensuring your parts stay robust and reliable in the toughest conditions. Choose C&H Machine for superior metal durability and performance.

For verification of efficacy, we can test with copper sulfate and water immersion.

Electropolishing

Enhance the surface finish and longevity of your metal components with C&H Machine’s electropolishing services. Following standards ES 2-82 and ASTM B912, our electropolishing process smooths and cleans “stainless” metal surfaces by removing a microscopic layer of external surface. This technique not only improves the aesthetic appearance but also significantly increases the corrosion resistance and durability of your parts. Choose C&H Machine for electropolishing services that deliver superior surface quality and performance, ensuring your components meet the highest industry standards.
