Conversely, trivalent chromium (Type II) is considered less harmful and is increasingly preferred due to its lower environmental impact. When sourcing alodine aluminum, inquire about the type of coating used and the supplier’s compliance with environmental regulations. Opting for suppliers that utilize eco-friendly formulations can enhance your corporate social responsibility profile and mitigate regulatory risks.
