Uses of Boron

Boron is an extremely hard solid, with a high melting point, low density and very low electrical conductivity. Boron fibres are used for making bullet-proof vests. The isotope of boron has a high ability to absorb neutrons and their metal borides are used in the nuclear industry as protective shields. The compounds of boron – borax and boric acid are used in the manufacture of heat-resistant glasses, glass wool and fibreglass. Moving to borax, it is used as a flux for soldering metals and provides a stain-resistant coating to earthenwares. Borax is also used as a constituent of medicinal soaps. The aqueous solution of orthoboric acid is used as a mild antiseptic.

Uses of Aluminium

Aluminium is a silvery metal with high tensile strength; it has high electrical and thermal conductivity. If conductivity is measured on a weight-to-weight basis, then it is found that aluminium has twice more electrical conductivity than copper. Aluminium forms alloys with copper, zinc, silicon, magnesium, and manganese and these alloys find application in day-to-day used products.

Aluminium is used in various industries and is an important metal. Aluminium and its alloys are used in the making of pipes, tubes, rods or plates. Aluminium foils are thin plates of aluminium which finds application in food storage. Aluminium is also used in making utensils because it has a high heat-conducting capacity. Its use though should be reduced and eventually replaced because it is toxic in nature.
In the transport industry, aluminium is used in cars for making engine blocks, cylinder heads, transmission housings and body panels.
