There are many methods to produce metal powders from valuable metals and alloys such as titanium, aluminum, stainless steel, iron, copper, nickel-based alloys and cobalt-based alloys. Atomization is generally viewed as the method of choice due to the geometrical properties of the powder particles that can be achieved. This makes it ideal for additive manufacturing (AM).
In the atomization process, the melted metal alloys are first refined and degassed, then poured into a gas nozzle, where the liquid material is disintegrated into metal powder by a high-pressure gas stream. Gas atomization, water atomization and direct reduction all rely on industrial gases and gas technologies. Gas atomization requires argon and nitrogen, whereas a hydrogen atmosphere is needed for water atomization followed by oxide reduction.
Linde gas supply - quality guaranteed
The choice of gas and the supply scheme is a crucial success factor in the production of high-quality powder feedstock, as the gas atmosphere has a major impact on productivity and quality. We can offer the right gas and supply modes depending on operating conditions such as the type of gas, the melt rate per batch, the atomizing flow and time, the total batch time and the atomizing pressure. Our high-pressure gas supply schemes and technologies help to atomize high-alloy metals to powder particles that are spherical in shape and uniform in density.
Our atomization test bench for advanced research into the atomization of metal powders can even help you optimize processes by focusing on gas structures. Based in Germany, this cost-effective bench replicates your manufacturing process and visualizes your gas flow and structure, enabling you to optimize your equipment and processes for higher atomization yields and stability.
Once you have sourced your powders, our ADDvance® powder cabinet can help protect your valuable feedstock against ambient air and humidity. This innovative cabinet was designed specifically to retain the quality of valuable, sensitive AM metal powders.
