Silver, copper, and iron wires were investigated as possible bridgewire materials. The wires were exploded by a l-microfarad capacitor charged to 2,000 volts. Peak power input to the bridgewire is relatively more important than the energy required for vaporization. Low boiling point, low heat of vaporization metals such as silver and copper permit greater energy transfer to an explosive than high boiling point, high heat of vaporization metals such as iron.
