Boron, chemical symbol B, is a trivalent nonmetallic element that never occurs as a free element in nature. In amorphous form, it is a brown powdery substance, while in crystalline form, it is hard and black. Boron has an atomic number of 5, a hardness (Moh's scale) of 9.3, and belongs to group 13 on the periodic table.

Usage[edit]

Because of the remarkable hardness of boron compounds, boron fibers are commonly used by the UNSC to reinforce other metals. One example is prior to Operation: FIRST STRIKE, when the Spartan-IIs of Blue Team used boron fibers to reinforce the hull of a captured Spirit dropship.[1]
