Electrical Steel (GOES)
Grain-oriented electrical steel forms the magnetic cores of power transformers — a chronic bottleneck in grid build-out. Listed by the US DOE as a critical material.
Every new AI campus needs large power transformers; a 2026 Resources Policy study identifies GOES as a particularly constrained enabling material for AI data centers.
Transformer lead times and limited GOES capacity are a recognized constraint for AI build-out.
Who calls it critical
Membership on each government list. “Strategic” marks a higher tier where the list has one; “group” means included as part of a group such as rare earths or PGMs.
Electrical Steel (GOES): key questions
- Where is electrical steel (goes) mined or produced?
- Country-level production data for Electrical Steel (GOES) is limited or withheld in USGS statistics.
- Is electrical steel (goes) a critical mineral?
- Electrical Steel (GOES) appears on 1 of the 10 official lists we track (United States (DOE)).
- Is electrical steel (goes) in short supply?
- Our supply status: Tight / restricted. Transformer lead times and limited GOES capacity are a recognized constraint for AI build-out.
- Why does electrical steel (goes) matter for AI infrastructure?
- Every new AI campus needs large power transformers; a 2026 Resources Policy study identifies GOES as a particularly constrained enabling material for AI data centers.
