Low Sales Ceramic Balls (Good quality)
Product Description
Grinding Zirconia Ceramic Balls
Ceramic balls are known for their exceptional performance, including resistance to special and magnetic fields, wear, and corrosion. They also offer lubrication and require no maintenance during operation, making them ideal for high and low-temperature applications. These balls can be used in harsh environments and special conditions. We specialize in the manufacturing and distribution of ceramic balls.
Material: ZrOâ‚‚
Density: 6.00 g/cm³
Color: White
Grade: G5, G10
