Titanium plate for eyeglasses, abbreviated as eyeglass plate, is a plate made of titanium material. It is divided into pure titanium eyeglass plates, titanium alloy eyeglass plates, and memory titanium eyeglass plates.
Titanium has good corrosion resistance, similar to platinum, and its mechanical properties are excellent. It is used in spectacle frames because of its light weight, flexibility, and corrosion resistance.
However, the production cost of titanium and titanium alloy glasses is very high, and the requirements for buckling, stamping, cutting and welding are very high. It is not easy to weld and electroplating. Welding must be done in vacuum. Therefore, the price is relatively expensive, only used in high-end glasses frames.
Since the introduction of titanium metal as a new type of spectacle material, it has been favored by more and more consumers for its advantages of lightness, corrosion resistance, anti-allergy and high strength. With the development of titanium materials and the increasingly mature processing technology, a variety of titanium-based frames such as pure titanium, B titanium, and memory titanium have appeared on the market. Among them, the purity of the frame of pure titanium material needs to reach 99.9% (excluding gaskets, screws, stipules and leg sleeves), and its logo is called PURETITANIUM, or Ti-P for short. However, some manufacturers have also carried out the above marking on some non-pure titanium or titanium alloy materials driven by interests. In addition, the majority of consumers have insufficient ability to identify pure titanium frames, which causes consumers to wear titanium frames. Rust, skin allergies and other phenomena have damaged the interests of consumers. The following introduces several simple methods for identifying pure titanium frames.
1. Weight by hand, usually the specific gravity of the alloy frame is about 8.9g/cm3, and the specific gravity of the pure titanium frame is about 4.5g/cm3. Since the weight of the titanium material is equivalent to half of the alloy frame, it is lighter by hand. This is one of the easiest ways to distinguish between titanium and non-titanium frames.
2. Observe the welding points of the nose pad stem and nose pad bucket, the welding of pure titanium material is vacuum oxygen-free touch welding, here the welding mark is "step" shape, the welding of alloy material is spot welding, the welding mark is "slope" This is one of the effective ways to distinguish between titanium and non-titanium frames.
3. Observe whether there is a gasket at the hinge joint. The pure titanium frame should not make titanium directly contact with titanium at the hinge part, otherwise it will be prone to wrinkles at the joint and poor expansion of the temple. Usually two thin shims are inlaid on the hinge part of the pure titanium frame to separate the upper and lower hinges. Therefore, checking whether there is a gasket at the hinge is also a good way to identify whether it is a pure titanium frame.
4. Use a magnet for the magnetic reaction, loosen the hinge of the frame as much as possible, and use the magnet to attract in the free movement state. If the temple swings under the attraction of the magnet, it means that the frame is not pure titanium, otherwise the mirror The frame may be a pure titanium frame.
The titanium plates used for spectacle frames are divided into three categories, pure titanium; TC4; and B titanium 15333, pure titanium is divided into soft and hard plates, general soft plates are slightly more expensive than hard plates, soft plates are generally The hardness is required to be 67-80 watts; stampable, hard board generally requires hardness 90-97 watts; can not be stamped, only wire cutting. The 15333 titanium material used for high-end spectacle frames has good elasticity and is difficult to process.
Advantages of β titanium as a spectacle frame and spectacle frame:
Beta titanium alloy is a titanium material that completes beta particles with delayed cooling at the zero boundary point of titanium. Its processing technology is higher than that of pure titanium. It has better strength, fatigue resistance and environmental resistance than pure titanium and other titanium alloys. Corrosion performance, shape plasticity is very good, it is in a solid solution state, its elastic modulus is low about 80GPa, slightly higher than that of titanium nickel shape memory alloy (about 60 GPa), it has high elastic recovery ( There is no permanent deformation after the arch wire is bent at a large distance), the hardness is low, it is easy to form, and it can be bent or formed into a complex shape without being broken. The spectacle frames made with it make up for the lack of elasticity of the temples of pure titanium frames, which have good elasticity and memory characteristics, and the processing performance and welding of β titanium alloy are excellent. The shape and style of spectacle frames made from them are The material of the new generation of glasses. Therefore, the spectacle frame of β titanium alloy is becoming popular as a kind of high-end decoration and a fashion in developed countries such as Europe and America. It has been widely used in the production of high-end titanium spectacle frame wire and temple wire.
