The tungsten carbide sphere has been ground to achieve the precise shape and size, meets grade 25 sphere tolerance, and has a precision tolerance. Tungsten carbide provides high hardness and wear resistance, and good corrosion resistance.

Tungsten carbide, also known as carbide, is an extremely hard alloy made from tungsten and carbon that offers high wear resistance as well as good corrosion resistance.

Tensile strength, used to indicate the material's overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation.
