ceramic ball / rubber / tungsten carbide / glass

Chromium steel
Low alloy hardened chromium steel balls, they show excellent hardness, wear resistance, very good surface finishing and dimensional stability. They are used in precision bearings, in the automotive field, in the pumps and valves, in the browning, polishing and milling fields.
Stainless steel
Balls available in all stainless steels families and different heat treatment states, they are characterized mainly for the good corrosion resistance behavior. They are used in micro pumps for aerosol, in the foodstuff, aerospace, chemical, medical, military and naval industry.
Carbon steel
Low/high carbon steel balls, they can be provided in several heat treatment states that affect their properties. They are mainly used for drawers and rolling bearings, in furniture and bicycle components, in the burnishing, milling, polishing and tumble finishing fields.
Metallic alloys
Balls made of brass, bronze, Ni base alloys (Hastelloy, Inconel, Monel), Co base alloys (stellite), wear resistant alloys (tungsten carbide, tool steels), special alloys with aluminum, titanium, and other not common materials. They are used in the aeronautical, foodstuff, chemical, pharmaceutical, oil & gas fields.
