Aerospace & aviation

The aerospace industry involves the design, development, manufacture, testing and maintenance of aircraft, spacecraft and related systems. The industry has unique materials needs due to the extreme environments in which its products operate, such as lightweight, high-strength, and corrosion-resistant materials to ensure safe and efficient flight. Aerospace manufacturers need materials that can withstand extreme temperatures, pressures and vibrations. The industry also requires materials that can withstand harsh environments, such as high-altitude exposure to cosmic radiation, ultraviolet light, and corrosive chemicals. 

Why Powders?

Metal powders are used extensively in the aerospace industry to manufacture aircraft and spacecraft components such as engine parts, turbine blades, heat exchangers, rocket nozzles, and structural components. The high strength-to-weight ratio of metal powders makes them ideal for lightweight structural components. Powder metallurgy techniques are used to produce complex parts that cannot be produced by traditional manufacturing methods. 

The metal powders produced by the ATO Lab Plus ultrasonic metal powder atomizers have specific properties desirable for aerospace applications. The powders have a narrow particle size distribution, which allows for consistent and uniform packing of the powder during compaction. The powders have excellent flowability and high particle sphericity, which ensures uniform packing density and high green strength during pressing. ATO metal powders have an extremely low oxygen content, making them ideal for use in high temperature applications where oxygen can react with the metal and cause oxidation. The ATO Lab Plus can produce metal powders in a variety of sizes and shapes, depending on the specific application requirements. 

The aerospace industry uses a wide range of metal alloys, including aluminum, titanium, magnesium, nickel and their alloys, refractory metals, and specialty alloys. Aluminum alloys are widely used for their light weight and high strength properties. Titanium alloys are used for their high strength-to-weight ratio and corrosion resistance. Magnesium alloys are used for their lightweight properties, but are highly flammable and require special handling. Nickel alloys are used for their high-temperature properties, while refractory metals such as tungsten and molybdenum are used for their high melting points.
