SAE 841 Sintered Bronze / Powdered Metal

Powdered metal offer both strength and flexibility.  Additionally, they offer a cost effective production process that includes oil impregnation or permanent lubrication.

ASTM -  B438, Grade 1, Type II
Military - MIL-B-5687D, Type I, Grade I
MPIF - CT-1000-K26

Heavy industry uses Sintered Bronze as machinery components, as self-lubricating pump parts, and as turbine blades. The military depends on them for reliability in weapons and aircraft; and the technique is used to fabricate exotic materials for space vehicles.
