Abstract:

Two pure aluminum foams were bonded using foaming of a low melting point precursor and the bonding strength was evaluated. Two rectangular pure aluminum foams with about 77% porosity was obtained by a precursor method. The commercial flux was applied to the bonding areas of pure aluminum foams. The low melting point precursor sheet manufactured from ADC12 aluminum alloy was put between the pure aluminum foams and was fixed in the stainless steel square tube. The specimen was heated in a muffle furnace. The four point bending test was carried out for the bonded specimen. Some bonded specimens were broken in the matrix. The flexure strength of the bonded specimen varies widely. This is because that a part of the cell walls of the bonded area was melted and broken.
