Höganäs AB, Sweden, a world leader in metal powder technology, has announced its latest innovation for the Powder Metallurgy industry, a new high precision toolbox for Fe+Cu+C mixes. The company stated that this innovation significantly widens the application areas for these materials, taking Powder Metallurgy to a higher level.
As sintered components get ever more complex in terms of geometry, resulting in deep and narrow filling gaps, the use of powder mixes providing superior filling performance and no or limited segregation is essential.
Höganäs states that its new high precision toolbox for customising Fe+Cu+C mixes is proof of its constant search for solutions that will take the PM industry to the next level. By providing benefits such as significantly improved dimensional stability and copper distribution, the toolbox enables production with extremely high tolerances, minimum scrap and less machining.
Newly developed lubricants, free from metal soaps, promote stain-free surfaces and less furnace maintenance. They also eliminate zinc emissions, thereby contributing to sustainability. “Our first experience of the new high precision toolbox comes from trying to improve the production performance of an existing Sint-D 11 mix”, stated Mr Herrmann, Plant Manager at Germany’s SHW AG.
“Initial large-scale production tests show very promising results. We hope to be able to confirm these findings as soon as possible and start using the mix in our daily production.”
Caroline Larsson, from Höganäs’ Commercial department, stated, “What we have done is actually pretty remarkable. We have, for example, managed to improve the dimensional stability of Fe+Cu+C mixes by 40%. Some people said it was impossible, but guess what, we just did it.”
“Fe+Cu+C is the most common alloy system used in Powder Metallurgy”, continues Caroline Larsson. “With the new high precision toolbox we make it possible for our customers to extend its applications even further,” concluded Larsson.
