Description


Infiltration is the process of filling the pores of sintered or unsintered compacts with a lower melting point metal or alloy. The IP series products can significantly enhance the performance of the substrate and impart the desired specific properties, such as improving the electrical conductivity of electronic devices or enhancing the wear resistance of metal parts. Additionally, this series of products can double the tensile strength of iron-based structural components and offers advantages such as low cost, simplified processes, and easy adjustments compared to traditional densification methods like re-pressing and re-sintering, powder forging, and warm pressing.


The IP series of high-efficiency copper-based infiltration powders effectively reduce the corrosion or dissolution phenomena associated with copper infiltration to negligible levels, and they perform well in typical atmospheres of various sintering furnaces.

IP-96 is a high-efficiency copper-based infiltration powder specifically designed for iron and iron-carbon compacts. The infiltration process results in parts with higher density, increased strength, toughness, hardness, and impact strength. The infiltrated parts are easy to electroplate, weld, or braze, and they exhibit improved machinability. This technology can also be used to manufacture sealing components, and the steel parts that have undergone infiltration can be subjected to conventional heat treatment.
