Iron aluminides were fabricated from waste metals (Fe sludge and Al can tip) by powder metallurgical processes. Mechanical alloying and combustion synthesis were effective to form intermetallic compounds. Relationship between the microstructure and mechanical property was investigated. The synthesized specimens could be densified by mechanical alloying of Al can tip, the microstructures could be changed with powder mixture condition, however, the bending strength showed almost same value.
