Antimony powder is a metallic powder we offer in 22 different particle size variations, from 2 to 45 microns. It can be optimized for a variety of uses ranging from brazing alloys to polymer composite fillers. Antimony's properties, like a high melting point, hardness and corrosion resistance, make it well-suited for metallurgy, while its semiconducting characteristics enable applications in electronics and photonics. Whether it's enhancing mechanical strength or electrical conductivity, our range of Antimony Powder provides the right particle size for your application.
