Infiltration
Infiltration wicks molten copper into a sintered iron skeleton, boosting density, strength and machinability. Huaxiao delivers infiltration as part of our ISO 9001:2015 certified Powder Metallurgy capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.
What Is Infiltration?
Infiltration is a specialized capability within our Powder Metallurgy service. Infiltration wicks molten copper into a sintered iron skeleton, boosting density, strength and machinability. It is chosen when parts demand the specific combination of geometry, tolerance, material and volume that this process delivers best. Our engineers select and fine-tune the exact parameters for your application to balance performance, lead time and cost.
