Pentlandite is an iron–nickel sulfide, (Fe,Ni) 9 S 8.Pentlandite has a narrow variation range in Ni:Fe but it is usually described as having a Ni:Fe of 1:1. It also contains minor cobalt, usually at low levels as a fraction of weight.. Pentlandite forms isometric crystals, but it is normally found in massive granular aggregates is brittle with a hardness of 3.5–4 and specific gravity of

Nov 03, 2019 · Physical properties. Nickel is a typical metal: solid at everyday temperatures, reasonably strong and tough, malleable (easytowork), and ductile (capable of being pulled into wires). It''s fairly easy to polish, a reasonably good conductor of heat and electricity, and quite magnetic as well. In its strength and toughness, it''s similar to iron (though less magnetic), though it''s much more

Nickel is a silverywhite metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium s Curie temperature is 355 °C (671 °F), meaning that bulk nickel is nonmagnetic above this temperature. The unit cell of nickel is a facecentered cube with the lattice parameter of
