Infiltrant Wire
The easier and more efficient powder metal alternative
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.
Advantages
- Easier handling without breakage problems
- Less waste and infiltrant scrap
- Improved productivity through faster assembly
- Increased strength and quality
- Consistency of size, strength and hardness
- Uniform copper distribution
Specifications
Technical details:
- Accommodates either the one-step or two-step infiltration method
- Can be placed on the top or bottom of the iron skeleton particularly benefitting the processing of thick parts
- Sintering temperatures from 2020 – 2060 degrees Fahrenheit
- Sintering times from 10-20 minutes
- Sintering atmospheres from 5-100% hydrogen.
For localised infiltration, shorter times and lower temperatures are recommended
Infiltrant wire is available in a number of standard sizes, shapes and diameters or can be customised to meet exact specifications.
Forms
Popular configurations:
- Single wire rings
- Multi-turn wire rings
- Straight-length slugs
