Heavy Tungsten Alloy Penetrators
Tungsten penetrators, which normally means tungsten alloy (W-Ni-Fe & W-Ni-Cu) penetrators, must withstand the shock incurred while punching through armor plating. Penetrators designed for this purpose have a greatly strengthened case with an especially hardened and shaped nose.

Tungsten alloy armor-piercing cartridges are available as small arms ammunition, primarily for use as an anti-materiel round, for armored vehicles, concrete bunkers, tanks, and other defenses, depending on the caliber of the firearms. This ammunition consists of a penetrator constructed of tungsten alloy or tungsten carbide, enclosed within a softer jacket, such as copper or aluminum. The product ammunition can range from rifle- and pistol-caliber rounds up to tank rounds.
T&D is an ISO9001:2015 certified domestic supplier of Tungsten Carbide, Heavy Tungsten Alloy, Copper Tungsten, Tungsten, Molybdenum, Tantalum, and Niobium either semifinished blanks or as precision-machined parts. We can deliver your order machined to your specifications as detailed in your technical drawings. Services are available for prototyping and low-to-high-volume production runs.
Modern equipment, low costs, and short lead times allow T&D Materials Manufacture to provide its customers with quality products and excellent customer service.
