Aluminum siding is the outer covering or cladding of a building meant to shed water and protect from the effects of weather. It provides electricity when the wall area comes into contact with electrical wiring such as light fixtures. It also interferes with TV and radio reception. The types of aluminum siding are lap siding such as single board, two board, double board and vertical board lap siding.
Aluminum-silicon powder admixture is placed in a graphite lined quartz crucible and melted in an induction heating furnace. A temperature of 1450 to 1500 is required to ensure complete melting and the temperature is maintained for up to five minutes. The silicon and aluminum powder are actually melted by contact with the graphite.
