"Eutectic alloys melt at a single temperature. Non-eutectic alloys have markedly different solidus 
and liquidus temperature, and within that range they exist as a paste of solid particles in a melt 
of the lower-melting phase. The pasty state causes some problems during handling; it can however be 
exploited as it allows molding of the solder during cooling, e.g. for ensuring watertight joint of 
pipes, resulting in a so called wiped joint."
