Titanium forgings have a variety of functions and features, mainly including high strength, corrosion resistance, lightweight, high temperature resistance, etc. These characteristics make titanium forgings widely used in many fields.
Functions and features
High strength : Titanium forgings usually have high strength and hardness, suitable for applications with large loads or high temperature and high pressure environments . For example, the strength of TC4 titanium forgings can reach 1.012GPa, the density is about 4.51g/cm³, and the elastic modulus is about 110GPa .
Corrosion resistance : Titanium alloys have excellent corrosion resistance and are suitable for environments that need to resist corrosion. Titanium is not corroded in some corrosive media, such as seawater, wet chlorine, chlorite and hypochlorite solutions, etc. Lightweight : Titanium alloy is a lightweight metal material with a density of only 57% of steel, a little more than twice that of aluminum, but three times greater than aluminum . This makes titanium forgings perform well in scenarios where light weight is required, especially in the aerospace field .
High temperature resistance: Titanium alloys still maintain good mechanical properties at around 500°C and are suitable for fields that need to work in high temperature environments. For example, when the aircraft speed reaches 2.7 times the speed of sound, the surface temperature of the aircraft structure reaches 230°C. Aluminum alloys and magnesium alloys can no longer be used, but titanium alloys can meet the requirements.
Good low temperature performance: Some titanium alloys still maintain good ductility and toughness at low temperatures and are suitable for ultra-low temperature environments.
Non-magnetic: Titanium is non-magnetic and is suitable for occasions that require non-magnetic properties, such as submarine hulls.
Low thermal conductivity: The thermal conductivity of titanium is only 1/5 of steel, 1/13 of aluminum, and 1/25 of copper. This feature can be used in some occasions.
Low elastic modulus: The elastic modulus of titanium is about 55% of that of iron, making it suitable as a structural material.
Application areas
Titanium forgings are widely used in many fields, including:
Aerospace: Used to manufacture aircraft engine fan blades, compressor disks, blades, rocket fuel tanks, etc.
Petrochemical industry: used to manufacture reactors, heat exchangers, pumps and valves and other equipment.
Medical field: used to manufacture artificial bones, joints and other medical devices.
Other fields: such as shipbuilding, chemical equipment, medical equipment, etc.
