Beschreibung
Zusammenfassung:	The invention relates to open-pored metallic foam bodies as well as a method for manufacturing thereof. These metallic foam bodies are allowed to be advantageously used with ambient environmental conditions causing a high corrosion to many conventional materials, and accordingly reducing the lifetime thereof frequently. According to the set object, the metallic foam bodies should have a low mass simultaneously with a high specific surface, and increased corrosion resistance under chemically aggressive ambient environmental conditions. An open-pored metallic foam body according to the invention is then developed such that it is formed from a nickel-copper alloy having at least 40 percent by weight of nickel and yet a porosity of at least 90 %.
