Expert Reviews

Dr. Mark Brown, (Georgia Institute of Technology in Atlanta,USA)

Metal balls are rolling, spherical elements that exhibit greater strength and toughness than plastic and ceramic balls. They have a sufficient hardness for many industrial ball applications, and most products are electrically conductive. Some steel, nickel, and cobalt balls can be magnetized. Metal balls made from certain alloys can also provide corrosion resistance and refractory resistance.

Dr. Darren Chandler, Ph.D(Manchester Metropolitan University, U.K)

Other applications for metal balls include proprietary, patented or specialty applications such as drilling equipment, hardness testers, swivel balls, pinball machine balls, weights, toys, bicycle parts, foosball balls, handles, knobs, skates, drawer slides, spacers, fillers, projectiles, marine parts, door locks, and coffee makers.

Metal chips are generally irregular shaped portions of metal fragments where the key to selection is the “available surface area.” Chips come in a variety of sizes and shapes which can range from being quite large (an inch or two in diameter to fractions of inches). Generally, the smaller the chips, the more surface area there is of the material being used.

Dr. Ms. Cristiana Barzetti,  (University of Cagliari-Department of Chemical Engineering and Material Science, Italy)

Pellets have hollow bases (the skirt area of the pellet) that are generally larger in diameter than the front section (known as the head of the pellet). This enables the skirt to effectively seal the bore against the pressure pushing on the base of the pellet while the friction on the head area is not too high.

Dr. Baron Augustin, Ph.D (TUM)(Technical University of Munich, Germany)

Metal Balls for valve applications include products for check valves and ball valves, as well as trunnion, segment, stem, three-way, four-way, poly or multiple way, and two-piece balls. Valve balls must have a controlled sphericity and sufficient tolerances for proper sealing against the valve seat.
