Titanium plate titanium alloy material introduction

[Tiarticle]

Titanium plate for glasses, referred to as glasses plate, is a plate made of titanium material, which is divided into pure titanium glasses plate, titanium alloy glasses plate and memory titanium glasses plate.

Titanium has good corrosion resistance and is similar to platinum, and its mechanical properties are excellent. Used in the glasses frame is light, flexible, corrosion resistant and so on.

However, titanium and titanium alloy glasses are expensive to produce, are highly demanding in buckling, stamping, cutting, and welding, are not easily soldered and plated, and must be completed in a vacuum. Therefore, the price is relatively expensive, and it is only used for medium and high-end frames.

As a new type of eyewear material, titanium metal has been favored by more and more consumers because of its advantages of lightness, corrosion resistance, anti-allergy and high strength. With the development of titanium materials, the processing technology has become more and more mature. There are many kinds of titanium-based frames such as pure titanium, B-titanium and memory titanium. Among them, pure titanium material frame purity requirements of 99.9% (excluding gaskets, screws, stipules and leg sleeves), its logo is called PURETITANIUM, or abbreviated as Ti-P. However, some manufacturers have also carried out the above identification on some non-pure titanium or titanium alloy materials, and the consumers have insufficient discriminating ability for pure titanium frames, resulting in the appearance of frames after consumers wear titanium frames. Rust, skin allergies and other phenomena have harmed the interests of consumers. Here are a few simple ways to identify a pure titanium frame.

1. By hand weight, usually the alloy frame has a specific gravity of about 8.9g/cm3, and the pure titanium frame has a specific gravity of about 4.5g/cm3. Since the titanium material has a weight 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 support and the nose support bucket. The welding of pure titanium material is vacuum oxygen-free welding. Here, the welding mark is "step" shape, the welding of alloy material is spot welding, and 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 directly contact titanium and titanium at the hinge part, otherwise the phenomenon of wrinkling at the joint and poor joint of the temple may occur. Usually, two thin shims are placed in the hinge part of the pure titanium frame to separate the upper and lower hinges. Therefore, checking the presence or absence of a shim at the hinge is also a good way to identify if it is a pure titanium frame.

4. Use a magnet to make a magnetic reaction, loosen the frame hinge as much as possible, and use a magnet to attract it under free-moving conditions. If the temple is shaken under the attraction of the magnet, the frame is not pure titanium, otherwise the mirror is The frame may be a pure titanium frame.

The titanium plates used in the frames are divided into three categories, pure titanium; TC4; and B titanium 15333, pure titanium is divided into soft and hard boards, generally soft boards are slightly more expensive than hard boards, soft boards are generally The hardness is required to be 67--80; it can be stamped, and the hardness of the hard board is generally 90-97; it cannot be stamped and can only be cut by wire. The 15333 titanium material used for high-end glasses frames is difficult to process.

The advantages of β titanium as a spectacle frame and eyeglass frame:

Β-titanium alloy is a titanium material which is delayed in cooling at the zero boundary point of titanium to complete β-particles. Its processing technology is higher than pure titanium, which has better strength, fatigue resistance and environmental resistance than pure titanium and other titanium alloys. Corrosion property, shape plasticity, solid solution state, its elastic modulus is about 80GPa, slightly higher than the elastic modulus of titanium-nickel shape memory alloy (about 60 GPa), it has high elastic recovery force (ie The arch wire has no permanent deformation after bending at a large distance. The hardness is low, it is easy to form, and can be bent or formed into a complicated shape without being broken. The spectacle frame made by the lens compensates for the lack of elasticity of the pure titanium frame, the elasticity and the memory characteristics, and the processing performance and welding of the β titanium alloy are excellent, and the spectacle frame and style made by the spectacle frame are more. A new generation of glasses for making materials. Therefore, the frame of β-titanium alloy is popular in the developed countries such as Europe and the United States as a medium-to-high-end decoration and a fashion. It has been widely used in the production of high-grade titanium frames and wire.
