Infiltration: Reliable Infiltration from Huaxiao
Infiltration fills the pores of a sintered iron-copper part with molten copper to boost strength, hardness, and density—a classic PM performance upgrade.
How Infiltration Works
A copper preform melts and wicks into the connected porosity of a sintered ferrous part during a second heat, sealing pores and improving properties.
Infiltration vs. Steam Treatment
Infiltration adds copper for strength and density; steam treatment grows an oxide surface for wear and corrosion resistance.
Materials
- Iron-copper PM—structural parts
- Steel PM—gears
- Bronze-infiltrated—bushings
Industries
Transmission, actuator, and hardware PM parts use infiltration.
How to Spec Your Infiltration Job
- Define base and target density.
- Note strength requirements.
- Set dimensional change limits.
- State surface needs.
- Provide volume.
FAQ
What does it do?
