A sintered metal connecting rod (10) includes as an integrated body, a large end portion (11), a small end portion (12), and a stem portion (13). In the sintered metal connecting rod (10), division marks (14a, 14b) of a molding die by a compression molding are formed between the large end portion (11) and the stem portion (13) and between the small end portion (12) and the stem portion (13) on one of front and back surface (11c to 13c) in which the through-holes (11a, 12a) are formed, respectively. The large end portion (11) and the stem portion (13) have a density difference of 4% or less, and the small end portion (12) and the stem portion (13) have a density difference of 4% or less.

A shaped charge liner including a composition of powders. The composition may include one or more of an aluminum metal powder and a titanium metal powder, a bronze metal powder, a tungsten metal powder and a graphite powder. Each powder of the composition may include grain size ranges that are different from one or more other powder grain size ranges. The bronze metal powder may include two or more different grain size ranges, and in some instances three or four different grain size ranges. A method of making the shaped charge liner and shaped charge with such liner having the composition of powders is also disclosed, as is a shaped charge including such shaped charge liner.

A system and a method of making an object from powdered metal are provided. The method includes feeding the powdered metal into a first end of a die. The die is rotated to pull a first portion of the powdered metal into a pressing zone. The first portion of the powdered metal is pressed using high pressure. The die is further rotated to release the first portion of the powdered metal from a second end of the die. A second portion of the powdered metal is then pulled into the first end of the die.
