Silver has antibacterial properties, but silver is a heavy metal. How do you control heavy metal excess? Do you have relevant test data?

The company controls heavy metal excess through the following methods:

• Selecting lead- and cadmium-free fine gold and fine silver raw materials exclusively supplied by the China Gold Research Institute.
• Employing the patented “low-energy multiple impact” process and special surface polishing treatment, which effectively addresses the issue of silver element migration and heavy metal excess.
• Obtaining qualification certification for heavy metal silver migration in water from the Chinese Academy of Sciences (CAS) and CAS Xiangshi testing, as well as EU REACH (249 items) testing qualification certification.
