Product Description

Product Description

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 balls for your application. Balls coated with such as DLC(diamond like carbon), obtain a series of comprehensive excellent properties, such as good wear resistance, low friction coefficient, good corrosion resistance etc. The smoothness of carbide ball we produced can reach mirror R0.4. 

As a professional tungsten carbide balls producer, Miller carbide keeps stock in sizes of 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm,4.0mm, 5mm, 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, 8.5mm, 9.0mm,9.5mm, 10.0mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm,14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm, 19.5mm, 20mm

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…)
