A method of using electrically initiated primer systems that rely on vaporizing a thin metallic film which is either coated on a non-conductive insulator component or is a malleable thin film or strip secured to the inner surface of a primer cup assembly to ignite an environmentally safe MIC composition.

Electrical initiation system

An apparatus and method of using electrically initiated primer systems that rely on vaporizing a thin metallic film which is either coated on a non-conductive insulator component or is a malleable thin film or strip secured to the inner surface of a primer cup assembly to ignite an environmentally safe MIC composition.

A lead-free percussion primer composition and a percussion cup containing e composition. The lead-free percussion primer composition is comprised of a mixture of about 45 wt % aluminum powder having an outer coating of aluminum oxide and molybdenum trioxide powder or a mixture of about 50 wt % aluminum powder having an outer coating of aluminum oxide and polytetrafluoroethylene powder. The aluminum powder, molybdenum trioxide powder and polytetrafluoroethylene powder has a particle size of 0.1 .mu.m or less, more preferably a particle size of from about 200-500 angstroms.
