How to identify Seiko pure titanium glasses frames

 

Seiko pure titanium glasses frames are famous for their craftsmanship,

 

Durability is synonymous with Seiko pure titanium glasses frames, the pursuit of elegance, fashion and high-tech perfect combination,

 

It gives people a high-quality, high-fashion, high-comfort aesthetic.

 

It is precisely because of its many advantages and good reputation that it has attracted many businesses to steal beams and change pillars to make profits! So how do we identify Seiko pure titanium glasses frames? If we want to identify Seiko pure titanium glasses frames, we must first know what pure titanium is.

 

Titanium has good corrosion resistance, similar to platinum, and its mechanical properties are excellent.

 

It is used in spectacle frames because of its lightweight, elasticity, corrosion resistance and other characteristics.

 

With the development of titanium materials and the increasing maturity of 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 pure titanium glasses frame is required to reach 99.9% (excluding gaskets, screws, brackets and leg covers),

 

The full name of its logo is PURETITANIUM or abbreviated as Ti-P, etc.

 

After understanding the pure titanium material, let's discuss how to identify the authenticity of Seiko pure titanium glasses.

 

1. Look at the sign.

 

Seiko's logo is SEIKO, and Seiko pure titanium glasses frames are branded on temples, nose pads, etc.,

 

Be careful not to make the low-level mistake of being deceived by similar trademarks when purchasing.

 

2. Weigh the weight by hand.

 

The weight of pure titanium frames is notoriously light, with a specific gravity of about 4.5g/cm3,

 

This is one of the simple ways to distinguish between titanium frames and non-titanium frames.

 

3. Look at the price.

 

Titanium and titanium alloy glasses are expensive to produce and have high requirements in buckling, stamping, cutting and welding,

 

Difficult soldering and plating welding must be done in vacuum.

 

So the price is relatively expensive, even if it is cheap, it will cost about four or five hundred,

 

If the price is too low, there must be a problem with the quality.

The welding of pure titanium material is vacuum oxygen-free touch welding, and the welding marks here are "step" shaped.

 

The welding of the alloy material is spot welding, and the welding mark is "slope".

 

5. Look at the gasket at the joint of the hinge.

 

The pure titanium frame should not make direct contact between titanium and titanium in the hinge part.

 

Otherwise, it is easy to wrinkle the joint and the temples are not open and closed.

 

Usually two thin gaskets are inlaid in the hinges of pure titanium frames.

 

Split the upper and lower hinges.

 

6. Use magnets to do magnetic reactions.

 

Loosen the hinges of the frame as much as possible, and use a magnet to attract them in a free moving state.

 

If the frame is not adsorbed, it means that the frame is made of pure titanium.
