Tantaline
Tantaline is a registered trademark name of Tantaline A/S, Nordborg, Denmark. The trademark is used for metal core products containing a corrosion proof surface of the element tantalum.

The tantalum surface is deposited by a gas phase process – an alloy bonding procedure - that creates a metallurgical bond between the metal core and the tantalum surface layer.

Tantaline alloy bonded products have it advantage in severe acidic corrosion environments like sulfuric acid; hydrochloric acid, nitric acid and phosphoric acid at elevated temperatures as valves, fittings, thermowells, fasteners and laboratory size chemical reactors.

In recent years the tantalum alloy bonding technology has lead to a number of innovative products, like a new range tantalum heat exchangers from Alfa Laval launched in 2014. It combines low capital cost, long lifetime and minimal maintenance requirements results in significantly lower total cost of ownership compared to heat exchangers made of high-grade alloys, graphite, silicon carbide or glass.

Tantaline's technology has also shown to enable new demanding chemical processes like the sulfur–iodine cycle (S–I cycle) used for hydrogen production.
