Process influence of aluminum foam sandwich panel

(1) Rolling composite powder metallurgy foaming process can prepare high-performance foam aluminum sandwich panel material. Rolling composite process can make the core layer powder reach extremely high density. The foamed sandwich panel has good foam The structure and the core form an ideal metallurgical combination.

(2) The suitable foaming temperature of the foamable composite board is 615 ~ 620℃. If the temperature is too high, defects such as large-sized connecting holes will appear in the core layer.

(3) When the foaming temperature is 620℃, the foaming time of 4 to 6 min is the optimized process condition. If the foaming time is too long, the foam layer will collapse.
