10. Silver Alloy Powder:
Silver alloy powder is widely used in electronic devices, conductive bonding, and medical devices because of its good conductivity and corrosion resistance.
These 3D printed metal powders are processed by powder bed melting, powder extrusion, or powder sintering to produce metal parts with complex shapes and high performance. Different metal powders are suitable for different fields and application requirements, providing more choices and flexibility for the manufacturing industry.
For example, stainless steel powder is widely used in the automotive industry to manufacture high-strength, corrosion-resistant parts such as engine components, exhaust systems, and brake systems. At the same time, in the aerospace field, the lightweight characteristics of titanium alloy powder make it the preferred material for aircraft engine components, fuselage structures, and turbine blades. In addition, aluminum alloy powder is widely used in automobile manufacturing to manufacture body structures, chassis parts, and intake systems.
Nickel alloy powder is very important in the field of high temperature, and is suitable for the manufacture of hot parts in gas turbine generators, oil refining equipment and aircraft engines. Copper alloy powder is often used in the manufacture of conductive parts and micromechanical systems of electronic devices. At the same time, the application of lead alloy powder in the medical field is mainly concentrated in radiation protection equipment and nuclear medical imaging technology.
Tungsten alloy powder is widely used in the manufacture of high-temperature tools and electrodes because its high melting point, high density and high hardness make it very suitable for aerospace devices, electronic devices and chemical processing equipment. In addition, tin alloy powder plays an important role in the electronic welding process, providing high-quality welding points for electronic connections and packaging. Silver alloy powder is often used in the manufacture of conductive bonding, contacts and connectors of electronic devices.
Different 3D printing metal powders play an important role in the manufacturing industry, meeting the needs of various industries for high performance, lightweight and corrosion resistance.
