Technology & Products
Key Products
MA-CCR25L (CuCr alloy for L-PBF with high conductivity/resolution); MA-CCR25H (CuCr alloy for L-PBF with high strength); MA-HC-LOP (high-purity Cu for L-PBF/cold spray); MA-HC-3 (Cu powder for binder jetting/DLP); specialized for aerospace thermal management, data center cooling, induction coils
Technological Advantage
Proprietary atomizing and wet-reaction powder processes enabling tight morphology and size control for AM copper powders; deep R&D infrastructure and global supply chain from Mitsui Group.
Differentiation
Value Proposition
Precision-engineered metal powders - including copper powders for AM - manufactured through proprietary processes, offering customized particle size and morphology to meet demanding industrial and additive manufacturing specifications.
How They Differentiate
Offers copper-chromium alloys (MA-CCR25H) that surpass GRCop-42 with comparable strength/thermal conductivity at lower manufacturing costs; enables printing with 400W lasers (vs 1000W for competitors); achieves 99.5% relative density with minimal wall thickness (150-200μm); reduces pressure drop by 90% and thermal resistance by over 20% in DfAM cold plates
