Precision alloys are metal alloys with special physical properties (magnetic, electric, thermal, elastic) or with a rare combination of physical, physicochemical and mechanical properties, the level of which is largely driven by precision of chemical composition, absence of contaminants, corresponding alloy structure.

Precision alloys can be divided into several groups, depending on their properties:

1. Alloys with high electrical resistance (NiChrome, FeCrAl)

2. Soft magnetic alloys

3. Hard magnetic alloys

4. Alloys with given TCLE

5. Alloys with given properties of elasticity

6. Alloys with defined electrical properties

7. Superconducting alloys

8. Thermostatic bimetals
