HRL Laboratories, LLC, achieved another milestone for its 7A77 aluminum alloy and feedstock powder designed specifically for additive manufacturing when the material was officially authorized for parts on Formula One race cars.
HRL Laboratories, LLC, continues its research push to advance the state of the art in additive manufacturing (AM) of high performance alloys. The HRL AM team’s new paper elucidates the fundamental physics behind HRL’s expertise, which enables significantly improved control of how 3D-printed metals melt and solidify. The paper, Grain refinement mechanisms in additively manufactured nano-functionalized aluminum, was published online in September 2020 ahead of the November print issue of the journal Acta Materialia.
HRL Additive, a new commercial effort by HRL Laboratories, LLC, has secured the first commercial sale of its groundbreaking 7A77 high-strength aluminum 3D-printing powder to NASA’s Marshall Space Flight Center. The production plant is dedicated to producing the printable aluminum powder, designated as 7A77, the first additive feedstock registered by the Aluminum Association.
HRL Laboratories is commercializing its additively manufactured (3D-printed) high-strength aluminum, which has obtained the first ever registration of an additive alloy from the Aluminum Association. HRL will be granted registration number 7A77.50 for the aluminum powder used to additively manufacture the alloy, and number 7A77.60L for the printed alloy.
