wherein W is tungsten; T is one or more elements selected from the group sisting of titanium, zirconium and hafnium; M is one or more elements selected from the group consisting of molybdenum, tantalum. iron, cobalt, nickel,manganese and vanadium; B is one or more of the elements selected from the group consisting of boron, carbon, silicon and aluminum; x is from 5 to 30 weight percent; y is from 1 to 10 weight percent; z is from 0 to 2 weight percent; and p is equal to or less than 30 weight percent. In this alloy p is approximately equal to the sum of x, y and z. A method of preparing this alloy and a kinetic energy penetrator manufactured from it are also disclosed.
