Application:

1.Aerospace field :

It is often used in the manufacture of aircraft structural parts, such as wing truss strips, fuselage frames, landing gear, etc., which can reduce the weight of aircraft and ensure structural strength.

2. Military industry field :

It can be used to manufacture parts of weapons and equipment, such as missile parts, armored vehicle structural parts, etc.

3.  Sporting goods :

For example, high-grade bicycle frames, golf club heads, skis, etc., its high strength can meet the performance requirements of sports equipment.

4. Mold manufacturing :

Structural parts used as molds, which can withstand greater pressure and wear.

5.  Mechanical manufacturing : Such as the key parts of the manufacturing machinery such as shafts, gears, etc.
