Today we are going to talk about titanium alloy, an amazing material known as ‘space metal’. It is used in aerospace and medical fields! However, what are the benefits and disadvantages for the human body?
The titanium alloy is prepared in a very strict process to ensure that no harmful substances such as lead, mercury and chromium are added to meet the standards for medical implants. This pure metal material not only does not release harmful substances, but also quickly forms a dense oxidised film after contact with air. This film has a good antibacterial effect, can effectively inhibit the growth of bacteria, for our drinking water health to build a solid barrier. Moreover, titanium alloy also has good biocompatibility, it will not react with human tissues and will not affect the physiological functions of the human body. Therefore, it is very suitable to be used in the medical field to make artificial joints and bone plates.
In addition to being non-toxic, titanium alloys are favoured for their powerful antibacterial properties. The oxide film formed on its surface not only gives the metal its unique colour, but also plays an invisible role in inhibiting bacteria. When microorganisms try to attach themselves to the titanium surface, the oxide film effectively prevents them from growing, thus achieving a bactericidal effect. Compared with traditional antibiotics, the antibacterial effect of titanium alloy is more durable and stable, and there is no need to worry about the possible problems of drug resistance arising from long-term use. This characteristic makes titanium alloy highly valued in the field of tableware, jewellery and even medical equipment.
However, titanium is not perfect. Pure titanium thermos cups, despite their hard surface, can be damaged by bumps or scratches. Although pure titanium has excellent corrosion resistance, prolonged exposure to harsh environments or strong impacts may still damage it. Therefore, it is recommended to avoid contact with sharp objects when using pure titanium insulated cups and to store them properly to avoid unnecessary damage. In addition, for other types of titanium products, it is also necessary to choose and use reasonably according to the use of the scene and precautions.
Titanium alloys also perform well in high temperature use. It has a melting point of 1,662 degrees Celsius, which means that titanium alloys remain stable in regular high-temperature environments without melting or deforming. This property allows it to be used in a wide range of applications in the aerospace industry, such as in the manufacture of high-temperature components for aircraft engines and rockets. In addition, titanium alloys have good thermal conductivity, which enables them to transfer heat quickly, thus maintaining an even temperature distribution of the workpiece or equipment and avoiding damage due to localised overheating. However, high temperature use also requires special attention to safe operation and protective measures.
