Researchers from the National University of Singapore have developed an innovative alloy that combines pure magnesium with powder from dried mango leaves. This new material, which utilizes agricultural waste, increases the metal’s vibration damping capacity by 54%, according to a study published in the journal Metals. The technique represents an eco-friendly alternative for creating high-precision structural components.
Magnesium, known for its low density and excellent machinability, is mixed with 5% mango leaf powder. During the sintering process, the leaves vaporize, generating micropores in the metal structure, which enhances impact absorption capacity. The team set the extrusion temperature at 350 °C to maintain the mechanical integrity of the material.
This collaboration between metals and plant biomass could revolutionize the industry, especially in sectors such as aerospace and automotive, where strength and lightness are critical. Scientists believe this strategy opens new opportunities for more sustainable engineering. Additionally, research is being conducted on the use of other agricultural waste, such as rice husks and nut shells, to continue improving the mechanical properties of materials for various applications, as mentioned in other studies on the topic.
