Abstract
A substantially lead-free tin alloy composition that may be used with sheathed explosive devices in a variety of linear explosive devices, such as ignition cords, mild detonating cords, and linear shaped charges. The tin alloy may also be used as a liner for shaped explosive devices.
Claims16
A linear explosive device comprising:
- a sheath that is substantially lead-free, wherein said sheath is formed from a tin alloy comprising:
- a percentage of zinc of from about 1 percent to about 6 percent by weight, and
- a percentage of tin of from about 99 to about 94 percent by weight;
- wherein said sheath at least partially encases a reactive material selected from the group consisting of explosive material, deflagrating material, pyrotechnic material, and mixtures thereof.

An aircraft canopy fracturing system for creating an opening in the canopy comprising:
- a transparent material forming at least part of the aircraft canopy;
- and
- a linear explosive device, wherein said linear explosive device comprises a sheath that is substantially lead-free, and wherein said sheath is formed from a tin alloy comprising:
- a percentage of zinc of from about 1 percent to about 15 percent by weight, and
- a percentage of tin of from about 80 to about 99 percent by weight;
- wherein said sheath at least partially encases a reactive material selected from the group consisting of explosive material, deflagrating material, pyrotechnic material, and mixtures thereof.

A linear explosive device comprising:
- a sheath that is substantially lead-free, wherein said sheath is formed from a tin alloy comprising:
- a percentage of zinc of from about 1 percent to 15 percent by weight, and a percentage of tin of from about 80 to about 99 percent by weight;
- wherein said sheath at least partially encases a reactive material selected from the group consisting of explosive material, deflagrating material, pyrotechnic material, and mixtures thereof.
A shaped charge explosive device comprising:
- a concave tamper;
- a reactive material disposed within the tamper, wherein the reactive material is selected from the group consisting of explosive material, deflagrating material, pyrotechnic material, and mixtures thereof;
- and
- a substantially lead-free liner formed from a tin alloy comprising:
- a percentage of zinc of from about 1 percent to about 6 percent by weight, and
- a percentage of tin of from about 99 to about 94 percent by weight;
- wherein said liner at least partially encases the reactive material within the tamper.
