Product Introduction
Nickel fiber felt is a high-performance material made from pure micron-level nickel fibers using a special felt laying process and ultra-high temperature vacuum sintering process.
This material offers several advantages over nickel mesh or nickel powder sintered plates due to its excellent three-dimensional network porous structure, high porosity, large specific surface area, uniform pore size distribution, strong corrosion resistance, good water permeability, good heat dissipation, stable performance. Additionally, nickel fiber felt has a long life expectancy.

Manufacturing flow
Nickel wire→Cluster drawing→Nickel fiber→Fiber shear→Air-laid→Sintering→Nickel fiber felt
Nickel fiber felt is manufactured through a process that involves cluster drawing of nickel wire, fiber shearing, air-laid netting, and sintering. The key step in this process is fiber drawing, which is performed using the cluster drawing method. Compared to other methods, cluster drawing offers advantages such as uniform wire diameter, easy continuous production, and low cost. This method can produce nickel fibers with different wire diameters ranging from 6 μm to 40 μm to meet the requirements of different types of nickel fiber mats.
The fiber shearing process is carried out using a special cutting machine that produces fibers of uniform length and high production efficiency. These fibers are then laid into a net using the airflow method with an imported felt laying unit. By adjusting various process parameters, the resulting nickel fiber net has good uniformity with no defects such as bundled fibers or fiber agglomeration. The single weight can also be controlled as needed.
