Will titanium alloy rust? The answer is here.

At first, I was also skeptical about whether titanium alloys would rust, as metal rusting is too common. But after checking the information, asking the boss, and personally trying it out for over a year, I found that titanium alloy is really super resistant!

The reason why titanium alloy is not easy to rust is entirely due to the stable oxide film layer. This layer of film is like a hidden armor piercing through the titanium alloy, separating the internal and external water, oxygen, acid and alkali. Moreover, it has super strong self-healing ability, which can regenerate within seconds after being scraped off.

Of course, titanium alloy is not completely rust free either. In the presence of strong acids or high temperature and high salt environments, the oxide film may be damaged. But the environments we come into contact with in our daily lives, such as rain, sweating, and exposure to weakly acidic liquids, will not affect titanium alloys.

I have been using titanium alloy bicycle parts for over a year, and there is no rust at all. On the contrary, the stainless steel center shaft that was replaced at the same time has already grown rust spots. My friend’s titanium alloy insulated cup has not rusted even after half a year of use, it just has some stains that can be easily wiped off.

In summary, titanium alloys hardly rust in the environments we come into contact with in our daily lives. Its oxide film is the bottom gas that resists corrosion. So, if you are also looking for durable and worry free metal parts, titanium alloy is definitely a good choice!
