きる。 Further, nickel and aluminum, which are the main components of the foamed metal 1, react in a temperature range of 700 to 900°C to form an intermetallic compound of nickel and aluminum, and the two are integrated. The amount of this intermetallic compound can be changed by adjusting the thickness of the skeleton of the foamed metal 1, and thereby properties such as strength and heat resistance of the material can be controlled.
なお、発泡金属１の骨格の太さの調整はニツケ
