It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675～680?℃.
