Our Tungsten Carbide Balls Characteristics
Tungsten carbide balls are ideal for applications where extreme hardness must be accompanied by high resistance to wear and impact. They are well-suited to elevated temperatures, corrosion, humidity, abrasion, and poor lubrication conditions.
Our Tungsten Carbide Balls Mechanical Properties
• Ultimate tensile strength 220,000 psi
• Ultimate compressive strength 643,000 psi
• Transverse rupture strength 228,000 psi
• Modulus of elasticity 98,000,000
• Density (approx.) 0.54 lb./in.
• Specific gravity 14.85-15.5
• Electrically conductive slightly magnetic
• Low thermal expansion rate
The process of making tungsten carbide balls
1, Heading a ball
2, Flashing
3, Removing the "ring" around the ball, the slugs are then flashed. This flashing gives the ball a rough finish
4, Heat treating. This high temperature process hardens the ball.
5, Grinding. After the ball is heat treated, the ball is then ground to the approximate diameter of the finished tungsten carbide balls.
6, Lapping. This lapping process polishes the ball to the exact size required. This gives the tungsten carbide ball a shinny finish.
7, Inspection . The balls are measured either through a fine tuned tapered roller or by a digital micrometer. These devices are capable of measuring within millionths of an inch. once it is determined that the balls are within measured specifications, they are visually inspected through a high powered microscope. once they are approved by quality control, the balls are then packaged and shipped to the customer.
With advanced production facilities,detection equipment, excellent inspector team, strong technical force and scientific management methods, we ensure the product quality and have won the praise and trust of the majority of users.
