AM 4 AM’s HiperAL Aluminum Alloy Offers Enhanced Mechanical Properties for Lightweight Applications

AM 4 AM, a Luxembourg company specializing in the production of advanced metal powders for additive manufacturing (AM), says it has improved the mechanical properties of its HiperAL aluminum alloy for AM.

HiperAL is a zirconium derivative of a 7000 series aluminum powder produced by AM 4 AM’s patented cold plasma treatment. The enhanced mechanical properties reached 525 MPa in yield strength and 550 MPa in UTS. The company says this milestone represents a breakthrough achievement resulting from an extensive research and development collaboration with its partner, Pint.

The material is said to demonstrate best-in-class mechanical performance to reinforce its status as one of the best performing and cost-effective materials available in the AM sector. The material was originally developed through a collaboration between AM 4 AM, Sirris and LIST to create crack-free parts with best-in-class mechanical properties, and is well suited for space, aeronautic and automotive lightweight applications.

“We are thrilled to unveil the enhanced mechanical properties of our HiperAL aluminum alloy,” says Maxime Delmée, AM 4 AM CEO. “This achievement underscores our unwavering dedication to innovation and continuous improvement. It is not one small step ahead in the quest of the aluminum with the highest mechanical properties. It represents for our customers a giant leap for economically viable applications of aluminum in AM. With HiperAL, we are empowering our customers to elevate the performance of their aluminum parts and reduce costs like never before.”

A key highlight of HiperAL is its yield strength of 525 MPa and UTS of 550 MPa, which the company says significantly surpasses conventional aluminum alloys, offering exceptional strength for demanding AM applications.

The material also enables extreme weight reduction. With its enhanced mechanical properties, HiperAL ensures a maximum weight reduction leading to a significant drop in materials consumption, processing time and ultimately costs. The company says HiPerAL is also an affordable, reliable material.
