Titanium frames introduced

Titanium is a chemical metal element, its refining process is more complex, less titanium material production and expensive, so early titanium metal only used in aerospace science, marine science and energy science and other high-tech development, but with the titanium industry technology The continuous improvement of daily necessities to 1965 also began to use titanium materials. The earliest titanium frame was invented in 1980, "riveted titanium frames," titanium is a very difficult to weld the material, there is no quick way to do the welding process, use rivets to nail it together. By 1981, some factories started to coat the titanium with a layer of nickel to facilitate welding.

Titanium frames can be divided into four types:

1. The first one is memory super elastic frame. This titanium nickel alloy frame has the characteristics of lightweight and super elasticity.

2. The second type contains 99.7% titanium metal, which does not include nickel metal. This is characterised by a lightweight, flexible and non-corrosive titanium frame.

3. The third is 96% titanium with the balance being aluminum, Vanadium... etc (ie TC4 Titanium or Ti1533).

4. The fourth type is about 75% titanium with the balance containing vanadium, aluminum, nickel, copper, etc., in order to ensure that the frame stiffer and more elastic.

How to distinguish between pure titanium frame

1. Check the weight.

2. Check whether there is magnetic reflection.

3. Select the structure of the hinge.

4. Check with chemical reagents.

5. Conductive index test.
