Lightweight Structural Alloys

With MBN’s proprietary MechanoMade® powders, various light alloys are available Nanostructured Aluminum Metal Matrix Composites reinforced with Al₂O₃-Al₄C₃ phases, achieving YTS of 560 MPa

MBN offers a complete end-to-end prototyping pathway for Al-based alloys and composites, starting from mechanical alloying to fully formed semi-finished components. Materials options include Aluminum matrix composites (Al-MMCs) reinforced with SiC for wear resistance, B₄C for lightweight armour and neutron absorption or AlN for thermal conductivity and stability

The Prototyping Process includes Powder Production- Nanostructured powders synthesised by mechanical alloying (Mechanomade®) and Forming Options such as hot isostatic Pressing, followed by extrusion, or direct extrusion of pre-heated green compacts

This integrated approach enables rapid development of advanced lightweight materials tailored for aerospace, defence, and automotive applications.

Titanium Aluminides (TiAl) are a class of lightweight intermetallic compounds that combine low density with outstanding high-temperature performance, making them ideal for aerospace and automotive applications. Developed via MBN’s proprietary Mechanomade® process, these powders feature precise composition control, tailored microstructures, and reproducibility across different particle size ranges (e.g. 45–106 µm, 45–130 µm).

With microstructures engineered as equiaxed, lamellar, or duplex, TiAl alloys offer tunable properties for advanced consolidation techniques including Hot Isostatic Pressing (HIP), additive manufacturing, and Spark Plasma Sintering (SPS). Their unique balance of mechanical strength, oxidation resistance, and creep stability up to 800 °C makes them a lightweight alternative to Ni-based superalloys.
