Thermal conductivity of titanium

It is said that metals have fast thermal conductivity. Titanium is a metal, and its thermal conductivity is naturally not slow, but it is relatively slower than some of our common metals. From current data, titanium has a relatively close thermal conductivity to stainless steel, about one fourth of aluminum, and about one fifth of iron.

Everyone may think that the purer titanium metal is, the greater its hardness is. In fact, titanium's hardness is not very high. On the contrary, some non pure titanium has surprisingly high hardness, and some impurities can improve its hardness even more.

Titanium is a rare metal. The reason for this idea is that titanium is too stable and difficult to develop and smelt. Therefore, it is natural for everyone to think so if they see little of it. In fact, the storage of titanium accounts for 0.6% of the region, ranking ninth, and the storage capacity is very large.

Titanium alloy is lighter than aluminum alloy. Although titanium alloy has a higher density than aluminum alloy, why do some devices that pursue lightweight still use titanium alloy? This is because titanium alloys have a higher strength to weight ratio, and thinner materials can be used to achieve the same strength and hardness. Therefore, shells and components made of titanium alloy are generally lighter than those made of aluminum.

The activity of titanium. Titanium metals exhibit different reactivity at different temperatures. Titanium is very stable in ambient air and is not prone to any reactions, but it has strong chemical activity at high temperatures and can easily react with many gases.
