Titanium processed parts refer to parts made of titanium or titanium alloy raw materials that are processed into specific shapes, sizes, and performance requirements through various mechanical processing methods. These processing methods include various processes such as cutting (such as turning, milling, drilling, etc.), forging, stamping, welding, surface treatment, etc. Titanium processed parts cover a wide range of products, from simple titanium bolts and shafts to complex aerospace structural components, medical equipment parts, and more.

Characteristics of titanium machined parts:

1. Excellent corrosion resistance

Titanium processed parts can quickly form a dense and stable oxide film (TiO ₂) in air or oxidizing media, which can prevent further contact between corrosive media and the titanium substrate and provide self-protection. It has good corrosion resistance to most organic acids, inorganic acids, alkalis, and seawater. In fields such as chemical equipment and marine engineering, titanium processed parts can work stably for a long time, reducing the frequency of maintenance and replacement. For example, titanium valve machined parts in chemical pipeline systems can resist corrosion from various corrosive media.

2. High strength and good toughness

Titanium processed parts have high strength, and their tensile strength can reach 300-1000MPa or more depending on different titanium material grades and processing techniques. At the same time, it also has good toughness and can withstand a certain degree of impact and deformation without breaking. This combination of strength and toughness enables titanium machined parts to perform well under external forces, such as titanium alloy wing machined parts in the aerospace field, which can meet the strength and toughness requirements during flight.

3. Good biocompatibility

Titanium processed parts have excellent biocompatibility, and the human body has minimal rejection reactions to titanium. In the medical field, titanium processed parts can be used to manufacture artificial joints, dental implants, medical device casings, etc. They can tightly bond with human tissues and will not cause serious adverse reactions such as inflammation during long-term use.

4. High temperature and low temperature resistance performance

The melting point of titanium is relatively high (around 1668 ℃), and titanium processed parts can maintain good performance within a certain temperature range. In high-temperature environments, although its strength decreases with increasing temperature, it can still maintain a certain level of structural integrity and strength at relatively high temperatures (such as 300-400 ℃), and can be used in some heat exchange systems in medium temperature environments. In low-temperature environments, titanium processed parts also exhibit good performance, such as titanium pipe fittings in low-temperature pipeline systems such as liquid natural gas (LNG) transportation, which can avoid cold brittleness and ensure the safe operation of pipelines.

5. Lightweight

The density of titanium is about 4.51g/cm ³, and compared to other commonly used metal workpieces such as iron workpieces and copper workpieces, titanium workpieces are lighter in weight. When applied in aerospace, automotive and other fields, it can effectively reduce the weight of the entire system, thereby improving energy efficiency or vehicle handling performance. For example, in the processing of titanium alloy landing gear parts for aircraft, their lightweight helps to reduce the weight of the aircraft and decrease fuel consumption.
