Aluminium Oxide Balls
Standard 99.5% alumina oxide ceramic balls have a proven ability to operate well in wear, heat, and corrosive situations as well as maintain dimensional stability at high temperatures. Oxide balls with a polycrystalline structure are lightweight and have good mechanical properties as well as resistance to heat, corrosion, and abrasion. They work well as electric insulators and vehicle lubricants.
