The ingredient is mainly the titanium,oakley sunglasses the platinum, the aluminum as well as the vanadium, the chromium and so on. Remembered that the metal mirror holder mixed the nickel and the titanium the alloy material which makes under the specific temperature, its most major characteristic is after receiving under the external force influence distorts, still might restore 98% shapes, may produce the super-elasticity results with this material manufacture mirror foot, even if after making an effort curving or the tautness, relaxes again, oakley sunglasses cheap still might reply the original condition. The titanium and the titanium alloy spectacle frames' marking common titanium material mirror holder the identification mark is Ti-P or TiTAN, indicated that besides the nose support, the hinge and the screw, other parts is manufactures by the titanium material. Ti-C expressed that a mirror holder's part manufactures by the titanium material. F-Ti-P or Front-Ti-P: Expressed that the pure titanium uses in the picture frame. T-Ti-P or Temple-P: Expressed that the pure titanium uses in the mirror foot. F-Ti-C or Front-Titan-C: Expressed that the titanium alloy uses in the picture frame. T-Ti-C or Temple-Titan-C: Expressed that the titanium alloy uses in the mirror foot.oakley sunglasses online The gold and the alloy pure gold assume the yellow, the density are 19.3 are one of heaviest metals, will not be corroded in the atmosphere the oxidation. Jin Biyin is soft, has the very good ductility, therefore does not need the pure gold to make the mirror holder material generally, but uses Jin Yuyin, alloy and so on copper.discounted oakley sunglasses This kind increased other metal alloy also to be called the K gold, the mirror holder material to use 18K, 14K and the 12K gold alloy.
