A new composite based on natural rubber vulcanizates loaded with the newly prepared iron oxide–aluminum oxide (Fe 2 O 3 ·Al 2 O 3 ) fillers were prepared and their physical and magnetic studies were investigated. The prepared fillers were evaluated as reinforcing fillers with some magnetic properties; these properties were dependent on the ratio of iron oxide to aluminum oxide in each prepared ratio of these fillers. Rheological properties of rubber mixes containing (1Fe 2 O 3 :3Al 2 O 3 ) and (1Fe 2 O 3 :1Al 2 O 3 ) fillers exhibited better properties than mixes containing (3Fe 2 O 3 :1Al 2 O 3 ) and (α‐Fe 2 O 3 ), which showed almost the same behavior. Physical properties such as tensile strength, stress at 100 and 200% strain, Young's modulus, and hardness were increased by increasing the volume fraction of the investigated fillers concentration in the mixed vulcanizates. Measured rheological and physical results were inversely related to the magnetic properties. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102:494–505, 2006
