Celmet is a porous metal in which triangular-prism-shaped cells are interconnected to form a three-dimensional structure having continuous pores. The products are available as nickel, nickel-chrome alloy, and aluminum materials. The porosity is significantly higher than that of porous materials derived from sintered metal powder or metal grains. Celmet is widely used in various industrial fields. Applications include electrodes for batteries and carriers for industrial deodorization catalysts.
98% Porosity Metal
Celmet consists of a porous metal body whose frame has a three-dimensional network structure similar to sponge. We are currently mass producing technologies for Ni (nickel) Celmet, and are providing this product to the automotive industry.
At this time, Sumitomo Electric has succeeded in developing Al (aluminum) Celmet. Characteristics include higher porosity of a maximum of 98%, light weight, high electrical conductivity, and greater surface area compared to sintered metal and metal fiber. Al Celmet can be used for various applications such as aerospace, automotive, energy fields, and much more.
