Tungsten carbide ball is commonly known as tungsten carbide bead, tungsten carbide sphere, hard alloy ball, refers to a ball made from WC powder with binders like colbalt, nickel, etc...Carbide ball is famous for its high hardness, wear resistance, corrosion resistance, and bending resistance. Therefore, it's ideal to be used in applications requiring extreme hardness and resistance to wear and abrasion, hard shocks and impacts, and it's ideal to be used as bearing ball.
Miller is an ISO certified professional manufacturer for tungsten carbide balls since 2008, and uniquely positioned to help you identify and source the correct carbide bearing balls for your application. The smoothness of bearing ball we produced can reach mirror R0.4. We keep stock of 0.4mm to 20mm in metric, 1/16″ to 1-1/4″ in inch bearing balls for your on time delivery and sizes could be customized, as we have a group of experienced technical personnel, advanced mould production equipments to realize your customization by drawing and sample.

Grade: Miller manufactured 4 main grade ( chemical composition) of carbide balls
1. WC92% + 8% Co (In request of more wear-resistance, we suggest to use WC-Co grades. )
2. WC92% + 8% Ni (In most corrosion-wear situations, an optimum choice is the WC-Ni grades, which are resistant down to pH 2 to 3.)
3. W85%-97%+Ni+Fe Tungsten balls (Density 15.5-18.5g/cm3, mostly are used in the field of shots and counterweight. such as the fish pendant, Oil drilling balance,Ball valves and bearings, Shotgun bullet, Armor-piercing bullet…)
4. W99.95% Pure tungsten balls (Density 19.0-19.2g/cm3, mostly are used in Aerospace, aviation, electrical Instrumentation, laboratory…)
