Problems solved by technology

[0011] The present inventor once aimed at the problems of difficult structure control and high reject rate in the above-mentioned foaming method or percolation casting method, and proposed a method using an electrodeposition method, using a non-water-soluble plating solution—anhydrous organic alkyl aluminum electrolysis The method of producing foamed aluminum by liquid solution fundamentally solves the structural stability problem of foamed aluminum, and prepares through-hole foamed aluminum with small pore size, uniformity and high porosity.
However, because the organic plating solution is flammable, it is the biggest hidden danger of safe production
