PHONETICS

IDENTIFICATION

Aluminium, also known as aluminum, is extracted from bauxite, is non-magnetic and does not easily ignite. A fresh film of aluminium serves as a good reflector with 92 percent of visible light and an excellent reflector (as much as 98%) of medium and far infrared radiation.
