In the previous article, we discussed “What happens if PD is wrong on glasses?“. In this article, let’s talk about “How long do titanium frames last?”.
Does the titanium frame cost a lot?
It can be decided according to the titanium frame technology, design, and specific material. Titanium-nickel shape memory alloy, titanium alloy, β titanium alloy frame belong to the high-end consumer goods, and the price is generally more than 300. In recent years, with the improvement of people's living standards in China, the domestic demand for titanium frames is expanding rapidly, and there are many manufacturers of titanium frames in China, but all the raw materials are still imported from Japan. Up to now, there are very few manufacturers that develop and produce titanium glasses frames by themselves in China. The production of β titanium alloy wire used in the frame is in the stage of development in China.
What are the characteristics of a titanium frame?
The so-called pure titanium, titanium refers to the purity of more than 99% of the titanium metal materials. To tell if a pair of glasses frame is pure titanium, we look at its purity. Because of the high melting point of titanium, lightweight, strong corrosion-resistance, used for the frame, they can wear for a long time, and will not let the bridge of the nose have a sense of pressure. But its disadvantage is that the material is soft, and only the relatively rough frame lines are made to ensure the stability and strength of the frame. Titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, not easy to deform and fade. General glasses frame contains copper, so when we wear for a long time .it will produce verdigris, namely, copper sulfate. It is a toxic substance and is harmful to the human body. Because pure titanium tends to be soft, copper has to be added to make the frames more stable, which is why the frames have to be replaced over time.
How long will the titanium frame last?
Titanium and titanium alloys are often used to make the most durable frames. Their strength is comparable to that of stainless steel. Medical facilities use titanium to make medical implants such as heart valves, showing just how durable the metal can be in extreme environments. Look at the maintenance between quality and use. Good glasses electroplating after three processes, the first is in the glasses or pure raw materials, plating a layer of an adhesion layer, used to attach the plating color layer. The second is the electroplating color layer. The third one is that after the electroplating color layer, another layer of electroplating protection is transparent. The electroplating of glasses through three processes can ensure that the glasses are not easy to lose color and damage in about 5 years. Now the glasses electroplating basically omits the processing of the last layer of the color protective layer, so the service life is about 3 years.
