Titanium alloy is a kind of metal alloy with titanium as the base element and its performance is improved by adding other alloying elements (such as aluminum, iron, chromium, nickel, etc.). Titanium itself has the characteristics of low density, excellent corrosion resistance, high strength and high specific strength (high strength to density ratio), good high temperature resistance, etc., which makes titanium alloy widely used in aerospace, aeroengine, shipbuilding, chemical industry, medical equipment and artificial bones.
The density of titanium alloy is about half of that of steel, which can reduce the weight of the structure and improve fuel efficiency in the aerospace and automotive fields.
A dense oxide film is formed on the surface of titanium alloy, which can resist the erosion of most acid and alkali media, so it performs well in corrosive environments such as seawater and chemicals.
Titanium alloys can still maintain stable performance at high temperatures, are not easy to soften or fail, and are suitable for applications in high temperature environments, such as high temperature parts of aircraft engines.
Titanium alloys have excellent biocompatibility with human tissues, so they are widely used in the manufacture of medical devices and artificial implants.
One of the most common titanium alloys, containing 6% aluminum and 4% vanadium, widely used in aerospace, medical devices and ships.
Medical grade Ti-6Al-4V alloy, with higher biocompatibility, used to make artificial bones and medical devices.
Contains aluminum, iron, titanium and other elements, has good impact toughness and welding performance, and is used for aviation structural parts.
Contains aluminum, iron, manganese and chromium and other elements, has good high temperature strength and creep resistance, and is used for aircraft engine parts.

Turbine blades made of equiaxed casting are widely used in aircraft engines and gas turbines. These blades have good high temperature strength and corrosion resistance, and are suitable for high temperature and high pressure parts of turbines.
Turbine disks are important components that support turbine blades and transmit power. The equiaxed casting process can produce turbine disks with good mechanical properties and durability, which are suitable for various turbine equipment.
Engine turbine accessories also include several key components, each of which plays a vital role in the high temperature, high pressure and high speed environment of the engine.
High strength and durability
Excellent fatigue performance
Complex shape manufacturing capability
Material diversity
