AU Metal

Description

Probably the first pure metal known to man, gold has been highly valued from earliest times. It is a yellow, malleable, ductile and soft metal, often alloyed to give it more strength. Gold is a good conductor of heat and electricity and is resistant to oxidation and most reagents. It is an excellent reflector of infrared and is extremely light reflective. The freezing point of gold serves as a calibration point for the International Temperature Scales.
