Specialists from the Institute of Light Materials and Technologies (ILMiT), part of the RUSAL group, presented a new composite material, RS-770K, for additive manufacturing. The development is 30% stronger than the most durable aluminum-based powder alloy.
In terms of strength characteristics, it makes a significant step toward steel and titanium alloys, while still retaining the lightness of aluminum.
The basis of the material is aluminum with the addition of ceramic particles, which provides a strength of 615 megapascals. Aluminum is 1.5 times lighter than titanium and three times lighter than steel.
ILMiT has created more than ten aluminum alloys for 3D printing. Additive technology makes it possible to form three-dimensional products by successively applying layers of material according to a digital model.
