ALUMINA HOLLOW BALLS
TYPE AHB
Alumina Hollow Balls Type AHB are sintered alumina hollow balls, which cleanly flow into confined spaces. Our standard product is our Type AHB-1 which ranges in particle size from 0.4 mm to 0.8 mm diameter. The melting point of AHB exceeds 2000°C. AHB can be produced in other size distributions on request. Please contact us for details
