Monel 400 and Monel 500 (often referred to as K-Monel) are Nickel base alloys used for balls in high corrosion and/or high-temperature applications. Monel balls and K-monel balls are used in non-oxidizing corrosive environments in the chemical pump, precision valves, pharmaceutical, marine, petroleum, textile, laundry, pulp, and paper industries. Monel and K-Monel balls are commonly used with seawater dilute sulfuric acid and monel and k-monel balls are highly resistant to alkaline (caustic) solutions. K-Monel balls are used where additional strength and hardness are required.
High precision zirconia balls are available in many sizes. Zirconia balls are most commonly used as check valves in flow control applications. When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes transformation toughening which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.
Bio ceramic for water treatment are mainly used as fillers for water filters. They are proven effective in the reduction of impurities including carcinogens like chloroform and heavy metals in water supplies.
Specified for use in high-technology industries such as aerospaace and defense. Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions. Light weight Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding and wear under high speed and acceleration. High Temprature Hardness is twice that of Steel.
Alumina Oxide ceramic balls may be used at temperatures up to 3180 'F. Ceramic balls are extremely hard, resistant to abrasion, and immune to all furnace atmospheres. Applications, where alumina oxide balls are used, include chemical pumps, down-hole pumps, valves, bearings, gauges, flowmeters, etc.
Silicon carbide balls are less frequently used than other ceramic materials. Due to its raw material costs and difficulty to machine. Silicon carbide offers the best heat and corrosion resistance of all the ceramic materials. Silicon Carbide is best used under low loads, low to moderate speeds and in highly corrosive environments. Used In : Ceramic Bearing & Ceramic Tube
Inconel balls can be made from a variety of Inconel alloys. Inconel alloys are nickel bases with chromium and iron. Many Inconel alloys were developed for specific applications. Inconel balls can be made from these various alloys to satisfy the need for mechanical properties at high temperatures and corrosion resistance to certain chemicals often at elevated temperatures. Inconel alloys generally have excellent creep and rupture strength and high tensile and yield strengths, especially at elevated temperatures. Inconel balls are made for use in jet engine applications where high temperatures exist. Inconel balls and seats have been used by NASA on the space shuttle launch pads. Inconel balls are also made for valves and pumps and other fluid handling equipment when corrosion resistance is required
