Nickel alloys, also called nickel-based alloys, consist, as the name implies, of nickel as the main constituent and at least one other chemical element. They are produced by means of a melting process.

Depending on the admixture of an element, they have various physical properties such as, for example

• a controlled thermal expansion,
• special magnetic properties,
• electrical resistance etc.

In addition, these alloys generally have good corrosion and/or high temperature resistance.

The following nickel alloys are commonly used:

• low-alloyed (nickel content of up to 99.9%)
• nickel-chrom
• nickel-chrome-cobalt
• nickel-iron
• nickel-iron-chrome
• nickel-copper
• nickel-molybdenum-chrome

Almost all nickel alloys are classified according to international standards.

Applications for nickel materials:

• in the automotive industry (catalysts and valves)
• in the chemical industry (chemical reactors, boilers, pumps, valves and heat exchangers)
• in power generation (power plant generators)
• in aviation (fasteners, engines and turbines)
• in oil and gas extraction (drilling tools)
• Environmental protection and waste management (flue gas desulphurisation plants, waste incineration plants)
• electronic and household applications (electronic circuits, computer manufacturing, kitchen appliances, cookers)
