How about tungsten carbide ball?

Tungsten carbide balls are precision components widely used in various applications due to their exceptional properties. They are known for their:

1. High Hardness and Wear Resistance: Tungsten carbide balls are extremely hard, making them highly resistant to wear and capable of withstanding harsh conditions.

2. High Elastic Modulus: With a Young's modulus of elasticity of 98,000,000 PSI, tungsten carbide is much stiffer compared to steel, which has a modulus of about 30,000,000 PSI.

3. Applications: These tungsten carbide balls are commonly used in applications requiring precision and durability, such as ball bearings, valves, ball screws, and flowmeters .

Overall, tungsten carbide balls are a critical component in industries requiring high precision and durability, including aerospace, automotive, and industrial manufacturing.
