The invention belongs to the field of building materials and particularly relates to a fire door made of foamed aluminum. The fire door made of the foamed aluminum comprises a door frame and a door leaf. The door leaf is made of foamed aluminum materials. A manufacturing method of the foamed aluminum comprises the following steps that a, aluminum is heated to 650 DEG C-680 DEG C so that the aluminum is melted; b, silicon carbon particles with the weight percentage being 2%-5% are added into the liquid aluminum and are stirred to be even; c, nitrogen gas is led into the liquid aluminum, and the liquid aluminum is stirred at the same time, wherein the rotating speed of a stirrer is 600 r/min-1,000 r/min; d, the liquid aluminum is cooled, so that the liquid aluminum is solidified, and a foamed aluminum plate is manufactured. The fire door is manufactured by utilizing the advantages of being light in weight, good in sound isolation, high in strength and resistant to fire of the foamed aluminum, so the defects that an existing fire door is clumsy and expensive are overcome; besides, the fire door is convenient to install and use, and the cost of the fire door is also lowered.
