Abstract
A frangible projectile for expelling from an industrial ballistic tool may be formed by a powder metallurgy process. A preferred embodiment of slug consists essentially of compacted and optionally sintered material and comprises up to 35% ferrotungsten in particulate form, up to 3% lubricant, and the balance iron in particulate form with inevitable impurities.
Claims22
A method for manufacturing a frangible slug for firing from an industrial ballistic tool, the method comprising:
- providing a mixture of powders having a composition that consists essentially of:
- up to 35 percent ferrotungsten in particulate form,
- up to 3 percent lubricant, and
- the balance iron in particulate form and inevitable impurities;
- compacting said mixture to form a compact;
- and
- sintering said compact to form the frangible slug.
