The chemical formula of mineral Arsenohauchecornite is indicated by Ni18Bi3AsS16. This mineral is usually found occuring in hydrothermal Ni-Co-Cu veins. This mineral is also commonly found at its type of locality at the Vermillion mine, Sudbury, Ontario, Canada. At Karagaily, central Kazakhstan, USSR. This mineral was named after an allusion to its chemical relation to the hauchecornite group. Mineral Arsenohauchecornite is known to crystallize in the tetragonal system of crystal formation. In optical mineralogy, this tetragonal system comprises crystals having three axes, which are all in a position perpendicular to one another. Two axes are usually found having the same or equal length.

            Mineral Arsenohauchecornite has no cleavage display even if it is closely evaluated with the aid of petrographic polarizing light microscope used in the field of optical mineralogy. Mineral Arsenohauchecornite is most commonly found colored bronze and is usually more splendid when viewed under polarizing microscope used in the field of optical mineralogy. The specific gravity measure of the mineral is usually found 6.35 grams per cubic centimeters. Most crystals of mineral Arsenohauchecornite are found opaque in appearance. Mineral Arsenohauchecornite is usually found exhibiting conchoidal fracture when viewed with the aid of polarized microscope. In the field of optical mineralogy, these fractures developed in brittle materials characterized by smoothly curving surfaces. The hardness measure of mineral Arsenohauchecornite when it is evaluated using the Mohs scale method is usually found 5.5. Arsenohauchecornite is usually found exhibiting metallic luster when viewed in reflected light of polarizing microscope for mineralogists. It is also most commonly found leaving a grayish black streak when rubbed on white porcelain streak plate. Arsenohauchecornite is a non-radioactive mineral as evaluated.
