A metal coupon for repairing a component includes an additively manufactured (AM) metal member having a sealed cavity in an interior of the AM metal member, and a porous region around the sealed cavity. A metal coupon system may include at least two AM metal parts with each AM metal part including at least a section of a sealed cavity therein and a porous region around the at least section of the sealed cavity. The AM metal parts combine to form the metal coupon, i.e., AM metal member, with the sealed cavity in an interior thereof and the porous region around the sealed cavity. In any event, the sealed cavity is hollow. The metal coupon with the sealed cavity provides reduced mass and allows braze material to be directed based on characteristics of the porous region of the metal coupon.
