Metal frame glasses have many advantages, It has a certain hardness, good softness, good elasticity, wear resistance, corrosion resistance, light weight, gloss and good color, etc. Below are some different metal materials frames with dfferent advantages.

1. High-nickel alloy frames: The nickel content is as high as 80% or more, mainly including nickel-chromium alloys, manganese-nickel alloys, etc. High-nickel alloys have better corrosion resistance. In addition, the material has good elasticity.

2. Monel frame: nickel-copper alloy, with a nickel content of about 63% copper and about 28% copper. In addition, there are small amounts of other metals such as iron and manganese. In particular, it is corrosion-resistant, high-strength, and firmly welded. It is used for mid-range frames. The most materials.

3. Memory titanium alloy frames: refers to a new alloy composed of nickel and titanium at an atomic ratio of 1:1. It is 25% lighter than ordinary alloys and has the same corrosion resistance as titanium. In addition, it has very good elasticity. Memory titanium alloy: It shows shape memory characteristics below 0℃ and high elasticity between 0-40℃. The corrosion resistance of memory titanium material is higher than Monel alloy and high-nickel alloy, but it is better than pure titanium and β -Titanium is slightly inferior.

4. Gold-coated frame: The process is to add solder or direct mechanical bonding between the surface metal and the substrate. Compared with electroplating, the surface metal layer of the coating material is thicker, and it also has a bright appearance, good durability and Corrosion resistance. The expression of gold-plated number: According to the regulations of the International Precious Metals Conference, products with a gold to alloy weight ratio of 1/20 or more are represented by GF, and products with a weight ratio of less than 1/20 are represented by GP.
