2.Advantages of amorphous alloys in robot manufacturing

Amorphous alloys have excellent performance due to their unique atomic structure and are emerging in the field of robot manufacturing. The following are several major application advantages of amorphous alloys in robot manufacturing:

(1) High strength and high hardness:

Amorphous alloys have strength and hardness far exceeding traditional crystalline alloys. This makes robot components more durable and able to withstand greater impact and load, improving the robot’s ability to operate in harsh environments. For example, robot joints and arms made of amorphous alloys are not only lighter, but can also withstand higher mechanical stress and extend their service life.
