Abstract

An example of a composition includes a host metal present in an amount ranging from about 95.00 weight percent to about 99.99 weight percent, based on a total weight of the composition. A flow additive is also present in an amount ranging from about 0.01 weight percent to about 5.00 weight percent, based on the total weight of the composition. The flow additive consists of an organic material that is pyrolyzable at a pyrolysis temperature that is less than a sintering temperature of the host metal. The composition is spreadable, having a Hausner Ratio less than 1.25.
