Pot metal is another name for white metal aloys which contain several 
of the following metals: tin, antimony, bismuth, zinc, aluminum, 
copper in various proportions. There are literally dozens of white 
metal alloys but most melt way below the point that alumaweld type 
materials flow. Typically they are liquid in the 500-700 degree F 
range although some are much lower. There is a solder for them that 
melts at 400 F but it is does not have a low viscosity.
