Product Examples
Many of today’s products are a direct result of cooperation between customers and us. As the list of existing products and applications has expanded, our experience within the application fields has also grown, giving us the capability to offer our customers the best possible recommendations and advice.
If the application is new, we will offer support by presenting available products and supplying test samples for trials, as the first steps towards finding an optimum solution.
In general, three properties are the most important: particle size, particle shape and chemical composition. Powders for Chemical and Metallurgical applications are available in a variety of particle sizes, but can be classified in four major categories: magnetites, sponge iron powders, atomized iron powders and electrolytic iron powders. They differ in particle shape and chemical composition, as illustrated below.

Magnetite
Magnetite, a form of iron oxide with an iron content of about 70%, can be used in many applications. We offer several powder grades with different particle sizes from the sub-micron scale up to a few hundred microns.

Sponge iron powders
Sponge iron powders are produced through solid-state reduction, which results in sponge-like particles with high surface area and internal porosity. In unannealed state, the typical iron content is 98.5%. However, after annealing the percentage increases to over 99%. Particle sizes vary from fine to coarse.

Atomized iron powders
Atomized powders are produced by rapid solidification of molten metal. In general, atomized iron powder particles are solid and contain no internal pores. In unannealed state, the typical iron content is 98%. However, after annealing the percentage increases to 99.5%. Particle sizes vary from fine to coarse.

Electrolytic iron powders
Electrolytic iron powder, the purest form of iron available, is produced by electronic deposition under controlled conditions. Powders of this type are commonly used in applications that require the highest level of powder purity. Particle sizes vary from fine to coarse.
