Product description
Osprey® M2 is a high-speed steel alloyed with tungsten and molybdenum. M2 is a general-purpose, high-speed steel exhibiting well-balanced toughness, wear resistance and red hardness properties. This grade is commonly used in cold work punches and dies, as well as high speed tool and cutting applications such as drills and milling processes.
This metal powder is manufactured by Inert Gas Atomization (IGA), producing a powder with a spherical morphology which provides good flow characteristics and high packing density. In addition, the powder has a low oxygen content and low impurity levels, resulting in a metallurgically clean product with enhanced mechanical performance.

Powder for Metal Injection Moulding (MIM)
Osprey® MIM powder has a spherical morphology, resulting in high packing density. This enables the manufacture of feedstocks with high powder loading, which not only minimizes binder costs but also reduces part shrinkage during debinding and sintering. Spherical powder also has excellent flow characteristics, resulting in reduced tool wear and consistent mould filling.
Osprey® MIM powder's low oxygen content allows better control of carbon and consistency during sintering. Low oxygen levels, together with high packing density, also facilitate faster sintering.
Powder for Additive Manufacturing
Osprey® metal powder for Additive Manufacturing is available in a wide range of particle size distributions that are tailored to the individual Additive Manufacturing systems. They can also be tailored to the particular requirements of the end application, both in terms of mechanical performance and surface finish.

Metal Injection Moulding (MIM)
Feedstocks of M2 powders (80% -22 µm) were prepared by TCK using their proprietary binder formulation to achieve a powder loading level of 61.8% corresponding to a 17.4% shrinkage factor. The feedstocks were molded in an Arburg injection molding unit to produce green standard MIM tensile and Charpy test specimens.1
A series of sintering cycles was run at temperatures in the range 1220–1250 °C with a standard heating profile of: 2 °C/min ramp to 1000 °C, 60 min hold, 2 °C/min ramp to sintering temperature, 60 min hold and furnace cool under a nitrogen atmosphere.
After austenitizing at 1190 °C and double tempering at 550 °C, samples were subject to tensile and hardness testing.
