[Generators and alternators](https://www.materialinsights.org/energy/e_generators/) (energy) and [Steel](https://www.materialinsights.org/commodities/steel/) (commodity): 2 relationships.

## How they are linked

### 1. Material need

*Physical flow · Direct · Steel → Generators and alternators*

Building or running Generators and alternators needs steel.

### 2. Price link: electrical steel

*Cost and price · Weak · Both ways*

Stator and rotor cores are stacks of thin electrical steel sheet, and frames are steel too. Yearly moves correlate at 0.21 with the steel index, a weak link because electrical steel is a specialised grade with its own supply and price.

- **0.00** monthly change correlation
- **0.21** 12-month change correlation
