There are many advantages when LM is used to Eyewear industry: 1. Complex structure can be formed; Liquid Metal can be formed like plastic, but it owns the character of stainless steel; dimensional tolerance is less than 0.03mm. 2. Hardness character: 2 times harder than stainless steel, scratch resistance is more than 6H (pencil hard); 3. Strength character: 3 times strength more than stainless steel, 2 times strength more than titanium alloy; can keep its shape when force removed; 4. Multiple surface treatment can be implemented. Such as coating/ plating/ etching/ laser color marking. 5. Radiation resistance;
