Abstract
Disclosed herein is a method of forming an alloy material for use in a wire. The method includes forming a master alloy containing lead and silver; and creating a molten wire alloy by combining the master alloy, additional lead, and a third material in a vessel. The method also includes flowing argon gas through and over the molten wire alloy. The method also includes drawing the molten alloy from the vessel through an actively cooled die, and solidifying the molten wire alloy to form a bar of wire alloy.
Claims17
A method of forming an alloy material for use in a wire, the method comprising:
- forming a master alloy containing lead and silver;
- creating a molten wire alloy by combining the master alloy, additional lead, and tin in a vessel;
- flowing argon gas through and over the molten wire alloy;
- drawing the molten wire alloy from the vessel through an actively cooled die;
- and
- solidifying the molten wire alloy to form a bar of wire alloy containing from about 95.5 wt. % to about 97.5 wt. % lead, from about 1.5 wt. % to about 2.5 wt. % silver, and from about 1.0 wt. % to about 2.0 wt. % tin.
A method of forming an alloy for use in a wire, the method comprising:
- melting and combining a first metal and a second metal to form a master alloy, the first metal having a first melting point, the second metal having a second melting point and the master alloy having a melting point of from about 460° C. to about 650° C.;
- forming a molten wire alloy by combining the master alloy with a third metal and an additional amount of at least one of the first metal and second metal;
- mixing the molten wire alloy in a vessel containing argon gas;
- and
- cooling the molten wire alloy while drawing the molten wire alloy through a die to form a wire alloy bar;
- wherein the first metal is lead, the second metal is silver, and the third metal is tin;
- wherein the wire alloy bar contains from about 95.5 wt. % to about 97.5 wt. % lead, from about 1.5 wt. % to about 2.5 wt. % silver, and from about 1.0 wt. % to about 2.0 wt. % tin.
