N. Ćirović et al. /Science of Sintering, 48 (2016) 1-16 2 1. Introduction Nanocrystalline nickel-iron-tungsten alloys have good electrical, magnetic and mechanical properties, high thermal stability and high corrosion resistance.
The non-magnetic cousin to tungsten nickel iron alloys is the tungsten nickel copper alloys. They are about as popular as nickel-iron alloys, but generally, have lower tensile strength (500-700 MPa) and ductility. They are great electrical conductors and are easy to machine despite their high mechanical strength. They possess excellent thermal ...

The results showed that the addition of both cerium oxide and tungsten oxide improved the NH3-SCR activity of magnetic iron oxide. Higher calcination temperature enhanced the high-temperature catalytic activity of Fe0.85 Ce 0.10 W 0.05 O z, although might decrease its low-temperature NH 3 -SCR activity.
Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions. Iron is magnetic in its α form. The α form occurs below a special temperature called the Curie point, which is 770 °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field.
