It is soft and brittle; superficially oxidized by air frequently becoming iridescent. Its reistance increases when placed in a magnetic field, and is soluble in nitric and hydrocholoric acids. Bismuth is often used in pharmaceuticals, cosmetics, low melting alloys; it can improve machinability of steels and other metals and be used to coat selenium. It also sees use in thermoelectic materials, pemranent magnets and semiconductors. Using BI 140 needles will allow you to have more surface area, and a tighter pack when melting.
