NITREX

NITREX METAL is a leading force in the heat treating industry, as an equipment manufacturer and developer of gas nitriding and nitrocarburizing technologies and solutions. Their revolutionary patented Nitreg® technology provides greater wear, fatigue and corrosion resistance to ferrous or non-ferrous materials, qualities much sought after by anyone whose product manufacturing activities involve any heat treatment process.


To this day NITREX has installed more than 70 nitriding systems only in the extrusion field, which is the best proof for the quality of their equipment. The company was founded in 1984 and since then it has gradually built up its position as a world leader on the market of nitriding equipment and technology. 


In aluminium extrusion factories the nitriding technologies are used to harden the surface of the extrusion dies. In addition to the initial treatment the nitriding is also used to restore the bearings of the dies after a certain number of extrusion cycles when the nitride layer is damaged by wear and by prolonged heating. Depending on the thickness of the profile walls and the complexity of its design the re-nitriding process can be repeated multiple times. 


The N-EXT technology is a completely new approach to the nitriding process. It allows a strict control of the nitrogen content of the white layer during the whole nitriding cycle. By improving the distribution of nitrogen throughout the shell you can achieve optimal properties of the material of the extrusion dies.
