Tungsten Foam

Tungsten Foam is a high-performance tungsten material with a porous structure, characterized by low density, high porosity, and large specific surface area. Its exceptional resistance to high temperatures and corrosion makes it suitable for use in harsh environments. As a result, tungsten foam has important applications in the fields of national defense, military, aerospace, and electronics. Shanghai Yuepeng can offer customized solutions for cell size, thickness, shape, and other parameters to meet specific requirements.
