The GBC Materials business of Morgan Advanced Ceramics (MAC) offers its dry pressed alumina ceramic balls for use in extremely harsh environments. These rolling, spherical components are said to be ideal for mechanical devices that provide rotary or linear motion, such as check and ball valves and bearings. GBC Material’s alumina ceramic balls can be used in a variety of industries, including electrical, environmental, chemical, material processing and automotive.
Alumina ceramic balls provide several advantages over comparable steel products, making them perfect for harsh environments, says the company. Alumina is resistant to extremely high temperatures as well as most corrosive substances. Balls manufactured with alumina are also stiffer, lighter, smoother, harder and more electrically resistant, providing increased versatility at a more cost effective price.
GBC Materials’ alumina ceramic balls provide low thermal conductivity and heat absorption, which allows for lower cooling requirements. The balls offer an extended product life, as they are resistant to wear and abrasion.
GBC Materials, based in Latrobe, PA, USA, manufactures the ceramic balls using precision made tooling and it is qualified through a rigorous inspection system. Through every step of the manufacturing process the company remains committed to quality. Highly trained personnel oversee each step of the process: tool design, material formulation, pressing, firing and final inspection.
The company manufactures the unlapped ceramic balls using different grades of alumina, from 85% to 99.5% purity. The company offers the alumina ceramic balls in a variety of sizes, including 1/5”, 3/8”, 7/16”, 1/2", 3/4" and 7/8”. To meet each user’s specific needs, GBC Materials will also manufacture customised sizes.
