More information
Alloy RS-553 is a high-strength, corrosion-resistant aluminum alloy designed for additive manufacturing (AM). Its key advantage is the achievement of peak performance through an annealing process, without quenching. RS-553 parts are fully weldable and machinable using standard methods for conventional Al-Mg alloys.
In combination with innovative AM-design, this material enables significant weight reduction, material savings, and superior mechanical performance for end-use components.
