DIN 17741 NiMn1 1/2 Hard – Premium Nickel-Manganese Alloy

The material NiMn1with the material number 2.4106 is applied in the form of strips, sheets, bars and wires for electro-acoustical construction components and in the chemical apparatus construction. As a result of the manganese content, NiMn1 possesses a higher strength than an unalloyed nickel material. The resistance to sulphur and the electric resistance are improved, too.
