[Aviation propulsion](https://www.materialinsights.org/energy/e_aviation/) (energy) and [Nickel](https://www.materialinsights.org/commodities/nickel/) (commodity): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Nickel → Aviation propulsion*

Building or running Aviation propulsion needs nickel.

### 2. Price link: superalloys

*Cost and price · Weak · Both ways*

Turbine blades, discs and combustors are made from nickel superalloys. Monthly moves correlate at only 0.15 with nickel, because metal is a small part of an engine's price and makers fix long-term supply deals for alloy.

- **0.15** monthly change correlation
- **-0.02** 12-month change correlation
- **-0.10** fitted elasticity
