1. Weigh the weight, the density of titanium is about 4.5.
2. To listen to the sound, tap the titanium tube lightly with metal to hear the sound is clear and clear without the tail sound. .
3. When the titanium pipe is cut with a grinder, the flame will be white, and the grinding wheel must be used. The ordinary grinding wheel for cutting steel pipes and stainless steel pipes cannot cut at all, and the steel pipes and stainless steel pipes will bear fire red.
4. Looking at the waste left over from processing, the titanium material is so thin that it is difficult to break it by hand, and it will break after repeated folding many times. This is a characteristic that other metals cannot have. This is also why titanium tubes can withstand high pressure and The reason why it will not explode when it reaches the limit.
