Fireworks Electrical Igniter Cable
Listed below are suggested high resistance wires for use in making electrical firing systems. General recommendations are that the wires used for ignition need a to have a resistance range of 650 to 875 ohms/cmf, with the higher end of the range being the best suited. Melt point of the wire needs to be in the range of 1100-1500° C.
