Get an instant online quote on 3D printed X1 Metal 420i parts. Certified to ISO 9001:2015, ISO 13485 and AS9100D.
X1 Metal 420i is a high-density metal composite made of 420 stainless steel reinforced with 40% bronze for enhanced wear resistance. This innovative material combines the strength and corrosion resistance of 420 stainless with the lubricity and anti-galling properties of bronze. The result is a durable alloy with over 95% density that exhibits improved mechanical performance and abrasion protection compared to standard 420 stainless steel. The bronze particulate blends uniformly throughout the 420 stainless matrix, delivering robust physical properties ideal for applications requiring high wear resistance with stainless steel’s inherent benefits.
The exceptional wear resistance and physical durability of X1 420i metal makes it suitable for 3D printing components subjected to highly abrasive conditions. Example uses include pumping equipment parts, downhole and mining machine components, molds and tooling, and decorative art pieces. The material’s composition of 420 stainless steel and bronze filler enables it to withstand abrasion and galling far superior to standard 420 stainless. X1 420i’s exceptional density and balanced material properties allow durable fabrication of industrial parts, tooling, hardware and more requiring stainless steel’s benefits along with enhanced wear performance.
