Our company has developed foamy fiber, which is a porous strengthening material. It is mainly made of iron together with carbon less than 0.02 wt.%. Fe is an element beneficial to the human beings. The NFJ foamy fiber，which is produced through special technique, is loose, porous, plastic, low density and with rough surface and resistant to rust. It has been widely used in the friction materials for railway and automobiles.

First, principle: NFJ non-rusting light foamy fiber material uses iron as raw material, and is subjected to high-temperature foaming by adding foaming agent at 1300 degrees high temperature through crushing, magnetic separation, air separation, grading, mixing and the like, and then passivation treatment at 900 degrees, finally made into rust-free, light, rough and loose porous. According to the requirements of different manufacturers, various products with different particle sizes are made. (-10 mesh to +300 mesh).

Second, good characteristics: 1)No rust 2)Eliminating static electricity 3) Prevent metal sparks and metal inlay 4) Light Weight 5) Improve friction performance 6) Slipping of conveyor belt in use can be reduced 7) Reduce noise 8) Reduce friction temperature 9)Easy homogenization during mixing
