Is tungsten-nickel-iron alloy magnetic?

In summary: Yes, WNiFe alloy is magnetic.

The magnetic properties of tungsten-nickel-iron alloy primarily come from its two key components: nickel and iron.

Nickel and iron are both typical ferromagnetic elements. This means they can be strongly magnetized at room temperature, making them important raw materials for manufacturing magnets and magnetic materials.

Tungsten itself is paramagnetic. Paramagnetic materials exhibit only a weak degree of magnetism in the presence of a strong external magnetic field; when the field is removed, the magnetism disappears. It does not possess the strong magnetic properties of iron.

When tungsten is sintered with nickel and iron through powder metallurgy to form a dense alloy, the alloy’s microstructure no longer consists of its individual elements, but rather forms a new phase. In this alloy, iron and nickel provide the foundation for ferromagnetism, giving the entire alloy a macroscopically magnetic appearance.
