Pentlandite is an iron-nickel sulfide (FeNi)9S8. 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 wt% levels. Pentlandite forms isometric crystals but it is normally found in massive granular aggregates. It is brittle with a hardness of 3.5 – 4 and specific gravity of 4.6 – 5.0 and is non-magnetic. It has a yellowish bronze color.
