Applications of free balls from various steels and alloys, polymeric and ceramic materials from 0.68 to 60 mm in diameter and with accuracy rating from 5 to 200 (Russian Standard 3722-81):

  • A high-grade chromium steel – in all the machine-building industry branches and in the production of consumer goods;

  • Stainless steel – in the machine-building industry, electrotechnics, medicine, as components of valves, for dosing equipment, in electric appliances and in mechanical pens;

  • Silicon molybdenum steel - in oil production and refining industry - in drill bits and turbo-drills;

  • Balls made of low-carbon steel for ammunition with environmentally friendly shot, round-nose copper-pated bullets with a caliber equal to 4.5 for air guns;

  • Brass – equipment for cars and other devices;

  • Cermet and polymers - in the valves of high-pressure pumps, operated in a corrosive environment, in various nodes assemblies of machines and instruments;

  • Polymers – in the production of consumer goods instead of steel balls.
