A high density metal component manufactured by powder metallurgy is disclosed. The powder metallurgy method provides metal components having a density greater than 95% of theoretical density using a single sequence of uniaxial pressing and heating. The metal components are manufactured from substantially linear, acicular metal particles having a substantially triangular cross section.

A method of manufacturing a metal component comprising: (a) forming a metal particle mixture, said metal particle mixture comprising: (i) metal particles, and (ii) about 0.015% to about 0.5% by weight of a lubricant, wherein the metal particles are substantially linear, nonspiralled, acicular partic

A method of manufacturing a metal component comprising: (a) forming a metal particle mixture, said metal particle mixture comprising: (i) metal particles, and (ii) about 0.015% to about 0.5% by weight of a lubricant, wherein the metal particles are substantially linear, nonspiralled, acicular particles having a substantially triangular cross section; (b) subjecting the metal particle mixture to a cold uniaxial pressing operation to form a green compact having a density at least 95% of the theoretical density of the metal component; and (c) subjecting the green compact to a heating operation for a sufficient time and at a sufficient temperature to pyrolyze the lubricant and to form the metal component.
