Spherical Alumina Fillers Market

The spherical alumina fillers market was valued at US$ 214.5 Million in 2023, and is expected to register a CAGR of 9.8% over the forecast period and reach US$ 497.5 Million in 2032.

Alumina powder used in filler is a high-performance material with high thermal conductivity, good heat resistance, high electrical insulation, high hardness, and low thermal expansion. The spherical nature of this powder allows for high flow-ability and high packing density, thereby enhancing thermal management in electronic components, and is widely used in thermal interface materials, automotive components, ceramics and polymers, and other systems. The material also exhibits excellent mechanical and dielectric properties and is used for producing advanced composite materials.
