Using nanoscale imaging, the team looked at the physical structure of tetrataenite, an iron-nickel alloy
, in each meteorite.
Noris Metallrecycling will deal in the collection, processing and trading of nonferrous and iron-nickel alloy
The team's results show that in the fourth millennium BC metalworkers had already mastered the smithing of meteoritic iron, an iron-nickel alloy
much harder and more brittle than the more commonly worked copper, developing techniques that went on to define the iron age.
The results confirm that already in the fourth millennium BC metalworkers had mastered the smithing of meteoritic iron, an iron-nickel alloy
much harder and more brittle than the more commonly worked copper.
An example of such a composite is Invar, an iron-nickel alloy
with a uniquely low coefficient of thermal expansion.
Already in the early 1950s it was recognized that the outer core is less dense than iron or an iron-nickel alloy
at corresponding conditions.
While attempting to develop an inexpensive international standard for the meter, the metric unit of length, Guillaume hit upon an inexpensive iron-nickel alloy
that expands very little when heated.
2MW smelter at the Mintek facility is capable of processing around 2,000 tonnes per month and producing Platinum Group Metals (PGMs) in an iron-nickel alloy
at an annualised rate of up to 70,000 ounces per year.
The ferronickel factory, also to be located in Moa, is expected to produce 68,000 tons a year of iron-nickel alloy
This ball is surrounded by a highly dynamic outer core of a liquid iron-nickel alloy
(and some other, lighter elements), a highly viscous mantle and a solid crust that forms the surface where we live.
