“…However, these composites were found to present high coercivity and low saturation magnetization due to the poor magnetic properties of iron oxide [7]. The aluminum metal matrix composites reinforced with 30% of iron oxide Fe 3 O 4 have shown a saturation magnetization of 13.43 A•m 2 /kg, and the Fe 3 O 4 reinforcement was found to reduce the electrical conductivity of the composites [10,11]. Fathy et al [12] investigated the magnetic properties of Al metal matrix reinforced with a 5% to 15% content of Fe particles as magnetic reinforcement.…”

This paper aims to investigate different properties of the Fe-Al matrix reinforced with multi-walled carbon nanotube (MWCNT) nanocomposites with the Al volume content up to 65%, according to the Fe-Al combination. In addition, the effect of adding Co content on the improvement of the soft magnetic properties of the nanocomposites was carried out. The nanocomposites were fabricated using the powder metallurgy process. The iron-aluminum metal matrix reinforced multi-walled carbon nanotube (Fe-Al-MWCNT) nanocomposites showed a continuous increase of saturation magnetization from 90.70 A·m2/kg to 167.22 A·m2/kg and microhardness, whereas the electrical resistivity dropped as the Al content increased. The incorporation of Co nanoparticles in Fe-Al-MWCNT up to 35 vol% of Co considerably improved the soft magnetic properties of the nanocomposites by reducing the coercivity and retentivity up to 42% and 47%, respectively. The results showed that Al-based magnetic nanocomposites with a high Al volume content can be tailored using ferromagnetic particles. The composites with a volume content of magnetic particles (Fe+Co) greater than 60 vol% exhibited higher saturation magnetization, higher coercivity, and higher retentivity than the standard Sendust core. Moreover, the produced composites can be used for the lightweight magnetic core in electromagnetic devices due to their low density and good magnetic and mechanical properties.

“…Moreover, in some studies, a significant increase in the magnetic saturation was observed by nickel addition along with nano Fe 3 O 4 to AA356 alloy. 37 Generally, the production of pure Fe 3 O 4 requires varying high-cost chemical processes. 38 On the other hand, MC is obtained after the magnetic separation of magnetite ores and used for metallic iron production.…”

The utilization of harder particles with magnetic properties as reinforcement in aluminum matrix composites (AMCs) enhances the mechanical and magnetic properties of aluminum. Present study investigates the utilization of magnetite concentrate (MC), which is composed of mainly Fe3O4, as reinforcement in AMCs. To achieve this goal, commercially pure Al and MC powders were blended (0–40 wt.% of MC) and ground by high energy ball milling, pressed, and sintered at 600°C for 30 min under an argon atmosphere. The products were characterized by XRD, and SEM analyses. Also, the density and porosity of the samples were determined by Archimedes’ principle. According to the results, it was observed that with the increasing reinforcement amount, agglomeration of the MC particles inside the Al matrix, as well as the porosities of the samples, increased. 10–20 wt. % of MC containing samples, the porosity values were obtained around 12 vol. %, however higher reinforcement amounts, raised the porosity values to 17.33 vol. % linearly. With the increment in both nonconductive MC particles and pores, the electrical conductivity of the samples decreased linearly. On the other hand, hard reinforcement particles played a positive role in both hardness and wear properties and a 43.37 HB of hardness value and 0.197 m3/N.m × 10−12 specific wear rate was obtained for the sample containing 40 wt. %, MC. In addition, an increase in magnetic properties was observed in direct proportion to the amount of MC particles added, up to 31 Am2.kg−1 of saturation magnetization.
