Tungsten Carbide Ball Fitting

Tungsten carbide ball fitting are a unique category of balls because they are manufactured in a sintering process, whereupon the metal powder is formed under extreme heat and pressure.  Tungsten carbide ball fitting are extremely hard (92 Rockwell).  The manufacturing technique makes these balls substantially more expensive than other materials, but practically inert. Their relative inertness makes them extremely resistant to interaction with various liquids and alloys.

Due to the strength of tungsten carbide, the balls are frequently used in the downhole tool industry for hard banding.  These are critical applications for the petroleum drilling industry. 

In a drastically different application, tungsten carbide ball fitting are frequently used as pen balls due to their inert chemical properties.  These balls are frequently used in miniature flow control devices, such as medical instrumentation and ink-jet printing.  Any time your company's products need balls with extraordinary strength and resistance to various chemicals, tungsten carbide balls from Thomson Precision should definitely be considered. 

Tungsten Carbide Ball Fitting Profile

High hardness and dimensional stability make tungsten carbide ball fitting the preferred choice for precision hydraulic valves, high-load bearings, inertial navigation systems, ball screws, linear bearings in sideways, gauging and checking instruments, and meters. Tungsten carbide balls are also used for ballizing, to work-harden and improve fretting fatigue strength. Tungsten carbide balls are standard for Rockwell testing, and for Brinell testing of materials in the range of 444-627 HB.

Tungsten Carbide Ball Fitting Characteristics

Tungsten carbide ball fitting 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.
