Fusion nib by Delta

Fusion: the new nib, invented by Delta.

It’s composed by a combination of different materials (so far, steel and gold) that give better functionality, enhancing the chemical-physical properties of ink with an assembly system adapted to increase the efficiency of the pen itself..
Moreover, the fountain pen is more precious and less expensive.
The FUSION nib shows a “plate” of precious metal (gold, or palladium, or other noble alloys) which, due to its high features of thermal conductivity, will tend to heat the underlying metal (steel, titanium or other); the underlying metal, in turn, transfers heat to the ink in transit between the conductor and the tip of the nib.
The higher temperature makes the ink flow more smoothly.
All the while, the nib will show characteristics of strength and durability for long writing sessions higher than all-gold nibs’ ones.
