Hazards from Frictional Sparks of Certain Light Alloys

LIGHT metal and their alloys have some attractive feat-ures e.g., lightness and strength which have led to
their widespread use in various fields. A drawback which certain of these alloys sillier from and which is not generally known, is their propensity to give frictional sparks. This propensity has been the cause of serious explosions in mines' and needs to be highlighted in it forum of this nature where metallurgists have gathered
to discuss all the aspects concerning light alloys
