Motor Lam Steel Sheet & Coil

Maximize useful electrical energy input with cold-rolled motor lamination steel sheet and coil from Alliance Steel.

Motor lamination steel is a specific cold rolled product tailored to create electromagnetic core materials for electrical equipment and components. Cold rolled steel has been rolled at room temperature, below its recrystallization temperature, which enables better control over finished product shape, thickness, dimensions and surface finish. While cold rolled and motor lamination steel manufacturing is similar, material composition and modifications to the annealing and tempering processes minimize energy loss from motor lamination products.

Alliance Steel’s cold rolled motor lamination sheet and coil service capabilities include slitting, shearing, blanking, leveling, degreasing and brushing, and metallurgical support.

Applications for Motor Lamination Steel Products

Motor lamination steel is often used to manufacture:

  • Electrical Equipment and Components
