Massive Selection for Pale Gold Bronze Powder - Spherical Alumina Powder for Thermal Interface Materials – Huarui
Massive Selection for Pale Gold Bronze Powder - Spherical Alumina Powder for Thermal Interface Materials – Huarui Detail:
Product Description
HRK series spherical alumina are produced by high temperature melting-jet method developing on ordinary irregular shape Al2O3, and then undergoes screening, purification and other processes to obtain the final product. The obtained alumina has high spheroidization rate, controllable particle size distribution and high purity. Because of its unique properties such as high thermal conductivity and good mobility, The product have been widely used as the filler of thermal interface materials, thermal engineering plastics and aluminum-based Copper-Clad Laminates and so on.
