Features of titanium eyeglass frames
Titanium alloy frames have low density, high strength, good mechanical properties and strong corrosion resistance. The frames are very light and resistant to corrosion by moisture.
But because of the poor process performance of titanium alloy, cutting is very difficult, so made of glasses to absorb hydrogen, oxygen, nitrogen, carbon and other chemical impurities more.
Titanium alloy wear resistance is poor, the production process is more complex, so every time with this material to make glasses frame, the cost is relatively high, the work is more complex, so relative to the ordinary glasses frame price is much more expensive.
Made of titanium alloy frames, due to the relative density of ordinary frames is much lower, so its firm performance is very strong, not easy to fall off or damage the skin.
The difference between pure titanium frames and titanium frames
Titanium frame will be slightly heavier than pure titanium frame, but these two are high quality materials, so from the appearance of people feel more comfortable.
Pure titanium glasses frame in the process of welding, will not contact with oxygen in the vacuum; One of the most effective ways to distinguish between the two types of frames is the welding of titanium frames (called spot welding), which produces a "slope" shape.
Pure titanium glasses frame in the hinge, will not be in direct contact with titanium; And titanium alloy glasses frame will directly contact titanium, easy to cause joint wrinkle, mirror leg has obvious tensioning phenomenon.
The proportion of pure titanium is generally 4.5, and titanium alloy is 8.9, the material is equivalent to half of titanium alloy. The result is a light frame to handle, which is the easiest way to distinguish between the two.
