Stronger AM Powder for Advanced Designs
Though aluminum 3D printing’s use in production has grown in recent years, low-strength AlSiMg still dominates the market. With the launch of 7A77 aluminum powder, California’s HRL Laboratories has created the strongest AM aluminum to date.
“HRL’s 7A77 is the first wrought-equivalent high-strength aluminum alloy available for additive manufacturing with strengths in excess of 600 MPa,” comments Hunter Martin, PhD, chief metallurgist at HRL Laboratories. “This strength provides exceptional design freedom for high-performance applications not yet explored in additive.”
