An alloy is made of a first material and a second material which has a substantially lower melting point than the first material, by (a) forming from the first material a body which has multiple fine interstices; (b) pouring the second material in the molten state around the body formed from the first material; and (c) allowing the resultant mass to cool. Thus, in the parts of the resultant mass in which the body formed from the first material was originally present, an alloy mass comprising the first metal and the second material alloyed together is made. Optionally, the body made from the first material may be preheated, desirably to a temperature higher than the melting point of the second material; and optionally the molten second material may be pressurized so as to enter into the interstices of the body. The first material may desirably be, for example, tungsten, cobalt, chromium, titanium, iron, nickel, silicon, manganese, copper, niobium, tantalum, vanadium, gold, silver, aluminum, molybdenum, zirconium, or zinc; and the second material may desirably be, for example, aluminum, magnesium, copper, lead, tin, or zinc.
