Precision Miniature Ball Materials

To meet the requirements of many industries like automotive and electrical, as well as different applications, NEMB manufactures balls from a wide variety of metals. While chrome and stainless steel are the most common metals used we have vast experience manufacturing balls from tungsten carbide, titanium, gold, copper, and brass to meet other demanding applications if necessary. Please choose from the material links to the left for more information. NEMB can also easily accommodate special customer requests such as passivation and coating.

Tungsten carbide balls and other specialty material balls are the backbone of NEMB's business. We pride ourselves on our ability to deliver the highest-quality miniature balls to our clients, regardless of material, grade, tolerance or application.
