Firearms and firearm components comprising bonded multi-metallic materials
View Patent ↗Firearms and firearm components are constructed from bonded multi-metallic base materials comprising at least two dissimilar metallic materials having different properties, such as weight, density, wear resistance, durability, hardness, and the like, bonded to one another. The components are fabricated such that the metallic material having higher impact- and wear-resistance is positioned at areas that experience impact, or that include bearing points, wear points, and interfaces with other components, while a lighter weight metallic material is positioned at component locations that don't have rigorous material property requirements. The bonded multi-metallic materials may be explosively bonded multi-metallic materials.

8. A firearm component of claim 1 , wherein at least one metallic material comprises an iron-containing metal and another metallic material comprises an aluminum-containing metal.
9. A firearm component of claim 1 , wherein at least one metallic material comprises an iron-containing metal and another metallic material comprises a titanium-containing metal.
10. A firearm component of claim 1 , wherein at least one metallic material comprises a titanium-containing metal and another metallic material comprises an aluminum-containing metal.
11. A firearm component of claim 1 , wherein at least one metallic material comprises an iron-containing metal and another metallic material comprises a magnesium-containing metal.
12. A firearm component of claim 1 , wherein at least one metallic material comprises a titanium-containing metal and another metallic material comprises a magnesium-containing metal.
13. A firearm component of claim 1 , wherein at least one metallic material is selected from the group consisting of one of the following stainless steels: 301, 302, 303, 303Se, 304, 304L, 309, 316, 316L, 410, 416, 440AQ, 440B and 440C.
14. A firearm component of claim 1 , wherein at least one metallic material is selected from the group consisting of: titanium, a titanium alloy of the R50000 series, and a titanium alloy having an ASTM B 265 designation ranging from Grades 1-5.
15. A firearm component of claim 1 , wherein at least one metallic material is selected from the group consisting of: aluminum, an aluminum alloy selected from the group consisting of 2024, 5086, 6061, 6063 and 7075, and an aluminum alloy containing scandium.
16. A firearm component of claim 1 , wherein the component is selected from the following: frame or body; slide; barrel; sear; stock; handle; extractor; sub-frame; receiver; block; door; roller; trunion; actuator; magazine well; housing component; trigger mechanism; safety mechanism; firing chamber; grip; plunger; ejector and sights.
17. A firearm comprising at least one of the components of claim 16 .
18. A firearm component of claim 1 , wherein the component is a semi-automatic pistol slide.
19. A firearm component of claim 1 , wherein the component is a semi-automatic pistol frame.
