[RoHS Compliant] Aluminum surface treatment that uses no Cr (chromium) at all. Ideal for switching from hexavalent chromate treatment!
Since no chromium (Cr) is used in the process, it is suitable for products that comply with environmental regulations. It also has excellent corrosion resistance and has passed the MIL standard salt spray test (ASTM B117) for 5%-168 hours. With thorough process management, there are few occurrences of defects such as stains or unevenness, and there are many successful applications as exterior parts. We can also accommodate matte finishes through shot blasting or chemical etching.
