Why is Nickel and Ferrous the same thing? : feedthebeast

Similar reasoning to bauxite/aluminum ore argument, bauxite is the ore, an impure form of aluminum, when purified makes aluminum ingots. well, if you smelt ferrous ore,IE the NiFe everyone has been posting about, they could be using the argument that it hasn't been purified of iron, so it is "ferrous" metal. other mod authors think, yeah you purified the ferrous ore, so you get pure nickel, it

geology Why is Earth's inner core made of an iron-nickel

Iron, nickel, and other heavy metals like gold, are what makes up the core of the earth because they are the heaviest of the metals and so sank toward the center of the earth. Also, since the earth is believed to have been made out of loose material (asteroids) out in space, it would make sense that it would be made out of much of the same

US6875949B2 Method of welding titanium and titanium

A method of welding titanium, and titanium based alloys, to ferrous metals is described. Welding of titanium, and titanium based alloys, is plagued with poor quality and highly brittle welds, substantially due to formation of Ti—Fe intermetallics in the weld pool. The instant invention provides supplementary filler material to alter the proportions of various elements in the weld pool.
