Antimony - NEY Metals & Alloys
Antimony in its stable form is a blue-white metallic element, with an atomic mass of 121.76g/mol. It melts at 1167°F (630°C) and makes a rather effective semiconductor. Although it looks metallic, antimony does not have the same chemical responses as a true metal. Antimony is also often added to lead to make the lead stronger.
