Advantages of Metal eyeglasses frames

Advantages: a certain degree of hardness, good flexibility, good elasticity, wear resistance, corrosion resistance, light weight, luster and good color.

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

2. Monel frame: nickel-copper alloy, with a nickel content of about 63%, copper and 28%, in addition to iron, manganese and other small amounts of metals, especially: corrosion resistance, high strength, strong welding, used for mid-range frames The most material.

3. Memory titanium alloy frame: 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 has the characteristics of shape memory below 0℃, and high elasticity between 0-40℃. The corrosion resistance of memory titanium is higher than that of Monel and high-nickel alloys, but it is better than pure titanium and β -Titanium is inferior.

4. Gold-clad 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 cladding material is thicker, and it also has a bright appearance, good durability and good durability. Corrosion resistance. The indication of the gold-clad number: According to the regulations of the International Precious Metals Conference, products with a weight ratio of more than 1/20 of gold to alloy are indicated by GF, and products below 1/20 by weight are indicated by GP.
