Advantages of titanium and titanium alloys and recognition of frames

  titanium company metal has good corrosion resistance, and platinum (commonly known as platinum) are similar, very excellent mechanical properties, texture, light, the unit weighs only 48% of the general metal, so titanium frames is the ideal material, because it has no phase than light, flexible, resistant to corrosion. However, the higher cost of production of titanium and titanium glasses, cutting, stamping, welding and plating,, aspects of the process have special high demand (for example: welding must be done in a vacuum), the price is more expensive.
   With the development of titanium materials and processing technology matures, the market has appeared in a variety of titanium-based titanium frame, B titanium, memory titanium. Among them, titanium frames purity materials required to achieve 99.9% (excluding gaskets, screws, stipules and leg sets), which identifies all known PURETITANIUM, or abbreviated as Ti-P and so on. However, driven by the interests of individual vendors for some non-pure titanium or titanium alloy materials have also been identified above, the majority of consumers lack titanium frames plus the ability to identify, causing consumers to wear titanium frame after frame of Health rust, skin allergies and other phenomena, harm the interests of consumers. Following the first volume of a few simple methods to identify titanium frames.

         1， A hand weigh the weight, the proportion of alloy frame usually about 8.9g / cm3, the proportion of titanium frame is about 4.5g / cm3, due to the weight of the titanium alloy materials equivalent to half the frame, hand weigh up more light. This is one of the easiest way to distinguish non-titanium frame titanium frame.

         2, observation stems nose pads and nose stipules bucket weld, welding titanium material is vacuum anaerobic Welding, welding marks here as "step" shape, welding alloys for welding, welding marks for "slope "shape, which is one of the effective methods of non-titanium frame titanium frame and distinction.

         3, observe whether there is hinged at the gasket, titanium frames in the hinge should not make direct contact with titanium and titanium, or prone junction wrinkled, temples and close them poor phenomenon. Usually two thin shim mosaic hinge titanium frames, the upper and lower hinge separated. Therefore, check whether the hinge pads, titanium frames also identify whether a good method.

         4, with the magnet magnetic hair should do, will try to loosen the hinge frame, under the free active magnet to attract, as the temple attracted by the magnet shaking, indicating that this is not a pure titanium frame, otherwise it shows that the frames may be pure titanium frame.

         Other titanium alloy frames and identifies the following:

         Titanium frame for frame + Titan-P or Ti-PPURETITANIUM

         Titanium is used to frame Front-Titan-P or F-Ti-P

         Titanium for temples Temple-Titan-P or T-Ti-P

         Titanium frames for frame + Titan-C or Ti-C

         Titanium is used to frame Front-Titan-C or F-Ti-C

         Titanium for temples Temple-Titan-C or T-Ti-C

         Some businesses to use only the frame is said to be pure titanium frame + frames are progressive price, customers tend to be easily fooled, so when you buy must recognize the label, so as not to be fooled.
