Aluminium and iron silicon alloys are widely used in the construction and automotive industries. Nickel-boron alloys are also used as ingredients in welding alloys and case hardening compositions in the engineering industry. In fact, Ferro boron (a 15 per cent boron compound) is widely used to inject boron into steel.

If the value of n is greater than 2, this element can also form alloys with these MnB composition metals. Boron can combine with other metals to form intermetallic compounds. When it comes to the lighter metalloids, alloys formed when transition metals are combined are extremely well represented. Optoelectronics, semiconductors, pyrotechnics, and electronics are all known to use metalloids. Metalloids and metalloid compounds are widely used as alloys (or as a component of alloy production), biological agents (which can be nutritional, toxicological, and medicinal), flame-retardants, catalysts, glasses and optical storage media. Metalloids have many other physical and chemical properties that are, in essence, intermediate.Metalloids have the ability to form amphoteric or weakly acidic oxides, and they can also form metallic alloys.These elements have intermediate ionization energies and electronegativity values and act chemically as non-metals (albeit in a weak way).Metalloids have electronic band structures that are similar to those of semimetals or semiconductors.The electrical conductivity of these elements is usually intermediate to strong.Metalloids are brittle, somewhat lustrous materials that are usually solid at room temperature.
