Is the titanium alloy easy to break?

People has a misunderstanding to the strength of "titanium alloy", titanium alloy is not a high strength material. Its specific strength is higher. The so-called "specific strength" is the ratio of intensity to density.

The products made of titanium alloy almost all are to use titanium alloy characteristics of low density and high strength, they are usually used in the combination place that required strength and weight. For example, the aircraft structure required light weight and high strength.

The density of titanium alloy is about 50%-60% of Steel No. 45, but the strength is equal to that of Steel No. 45 (titanium alloy is slightly higher than a little).

That is to say, the strength of titanium alloy screws and steel screws is quite equal, but only the titanium screws on the weight are light.
