초록 ▼

Numerous products can be formed by combining a low melting matrix made up of one or more metals and high melting, high density metal particles and wherein the products can be formed by adding the high density particles to a molten matrix metal and casting same, mixing powders of all the metals together, compacting and centering at a temperature in the low end of the melting range of the matrix alloy, or by mixing the high density particles into a paste of the matrix alloy and molding. These methods and compositions are particularly adaptable for use in forming low or non-toxic high density projectiles, such as, shot, bullets and pellets having a density comparable to that of lead while avoiding problems of toxicity associated with the use of lead.

대표청구항 ▼

The method of making projectiles, such as, shot, bullets, pellets and the like of a predetermined density comprising the steps of: (a) providing at least one low melting point metal having a density no greater than that of lead and less than said predetermined density; (b) providing at least one metal in powdered form having a density greater than said predetermined density and a melting point higher than the melting point of said low melting point metal, said high melting point metal powder being present in sufficient quantities to form a resultant mixture having said predetermined density; (c) melting said low melting point metal(s); (d) mixing said powdered metal(s) with said low melting point metal alloy until said powdered metal(s) is uniformly distributed throughout said low melting point metal(s) in a first vessel and advancing to a second vessel; and (e) continuously heating and stirring said mixture of low melting point metal(s) and said powdered metal(s) in said second vessel and discharging in droplet form therefrom.
