A Cadewld is composed of aluminum powder copper and a fluxing material. When 
fired it makes a alloy of the surface of the steel rod and the copper in the 
shot. All the copper wire, copper plating, and copper in the shot alloy 
together and create the molded cap you see. You can get carbon molds to weld to 
just about any combination of rods, structural steel, or copper wire sizes you 
can think of. The thermite (aluminum powder in suspension with oxidizer) was 
used in WW II and after to disable large guns by melting barrels or important 
parts of breach area
