Common Types of Nickel Alloys Used for Casting
Foundry companies use nickel-based alloys due to their durability. This particular alloy is known for
its corrosion resistance and ability to resist oxidation.
One can use the products made of copper-nickel alloy or other nickel-based alloys in harsh
environments. The nickel alloys can be divided into the following categories –
1. Wrought Nickel
In this variant of nickel alloy, the maximum carbon level is 0.15%. It is known for:
● Corrosion resistance in neutral or moderately reducing environments
● Tensile mechanical properties across a varied temperature range
● High electrical and thermal conductivity when compared to other nickel-base alloys due to being
ferromagnetic
The wrought nickel alloy is used in the chemical industry. The sand casting companies use this alloy
variant to manufacture the transducers or for articles that shield against electromagnetic
interference.
2. Nickel-Iron Alloys
The sand casting foundry uses this variant of nickel alloy for its soft magnetic properties.
● Alloys containing 36% nickel and 64% iron are used to manufacture –
o Thermostat rods and other precision measuring tools due to having almost zero coefficient
of thermal expansion at room temperature
o Items being used at cryogenic temperatures due to extremely low thermal expansion rates

● Alloys containing 72%-83% nickel are used in:
o Transformers
o Memory storage devices
o Inductors
o Magnetic amplifiers or shields
3. Nickel-Copper Alloys
The cupronickel alloy is resistant to corrosion by seawater, non-oxidizing salts or alkaline solutions.
4. Nickel-Chromium Alloy
This alloy variant is used in casting services due to being resistant to corrosion and scaling at average
and high temperatures. This variant of nickel alloy is also known for high electrical resistance.
5. Nickel-Molybdenum Alloys
This variant of nickel alloy contains 25%–30% molybdenum and is used for the production of:
o Stainless steels
o Special steels
o High-performance or Superalloy structures
6. Nickel-Chromium-Iron Alloys
This variant of alloy can be divided into two groups:
● Ni-Cr-Fe alloys
o Known for excellent strength at high temperature
o Ability to resist oxidation, carburization and any type of corrosion resulting from high-
temperature
● Ni-Cr-Fe alloys with Mo and Cu
o Known for excellent corrosion resistance in particular applications
