Infiltrant Wire

The easier and more efficient powder metal alternative

Share to Facebook Share to Twitter Share to LinkedIn

Infiltrant wire is the much-appreciated alternative to traditional powder metal (PM) copper infiltrants. These simple wire forms offer significant benefits over powder metal (PM) copper infiltrants.

The wrought/wire infiltration process melts high-specification copper alloys into sintered wire forms that are easy to handle and use. 

Infiltrant wire eliminates the need to store and handle bulky powder drums, while offering cost savings from the elimination of tooling, compacting presses, labour and the overheads that are typically required to produce infiltrant slugs. It also removes the inventory and manufacturing losses associated with oxidation, contamination, segregation, residue and erosion.
