Explanation

The porosity reaches over 90%. Porous metal with certain strength and stiffness. This type of metal has a high porosity content. The pore diameter can reach up to millimeter level. Its air permeability is very high, almost all of them are through holes_ The pore surface area is large, and the unit weight of materials is small. formed metal is produced by powder metallurgy method by adding blowing agent (such as NH, C1) into powder, and blowing agent volatilizes during sintering. Leave pores behind. The electrochemical deposition method can produce formed metal with regular shape pores and porosity up to 95%, including foam materials made of CXNi, NiCrFe, ZnCu, NiCu, NiCrW, NiFe and other metals and alloy skeletons. The metal electrochemically deposited on the porous body is connected into a whole through sintering. formed metal with high porosity and required strength can be used to fill more materials (such as catalyst, elonrolyte, etc.). formed metal is used to manufacture purification, filtration, catalytic stem, electrode and other devices in petrochemical industry, aerospace and environmental protection.
