One of the materials that Crystal Optics specializes in processing is "hard metal." This hard material has the disadvantage of being "hard" and "time-consuming to process," but it also has the advantages of being "easy to achieve machine precision" and "able to meet high mirror surface precision requirements." In high-precision parts that require special tools and wear resistance, our company has been involved in the processing of numerous hard materials. Among these, we frequently receive inquiries from many customers regarding "corrosion." This time, we would like to propose a new material in response to the "corrosion" of this hard material. 【Corrosion Resistance Comparison Experiment】 ■ Test 1: A drop of grinding fluid was placed and left overnight (approximately 12 hours) to check the appearance. ■ Test 2: Immersed in liquid for one month to check for corrosion. ■ Test 3: Immersed in a 10% nitric acid solution for 6 hours to compare corrosion depth and corrosion loss. *For more details, please refer to the PDF document or feel free to contact us.
