        Practical application value of Baoji titanium alloy

        [ Info Diffusion:Admin | Times:2019-12-06 | Hits:1916 ]

        An alloy composed of titanium and nickel is called a memory alloy. The alloy is formed into a predetermined shape, and after being shaped, if it is deformed by an external force, the original appearance can be restored by heating a little. This alloy has been used in many fields. For example, the antenna used in the US Apollo spacecraft is such a memory alloy; the Ninth People’s Hospital affiliated to Shanghai First Medical College has used this memory alloy for sterilization in women; it can also be used in fields such as instruments and electronic devices. . Titanium carbide (TiC) is quite like iron carbide and has a metallic luster. It has a higher melting point and higher hardness than iron carbide. Therefore, it has practical application value.

        Titanium has a lot of effects, and titanium products are also very good gifts. If you want to buy a good titanium gift, look for Baojibao Titanium Products Co., Ltd. It is absolutely good to see that you want to take it home immediately.
