SUY-1 | Soft Magnetic Iron (Pure Iron) Description :
SUY-1 is a mild steel with extremely low carbon and low impurities. This grade is specified in JIS C2504 "Soft Magnetic Irons" and is commonly referred to as "Pure Iron". SUY grades are classified from SUY-0 to SUY-3 according to their magnetic properties. 

Due to its very low carbon and impurity content, SUY-1 offers excellent drawability and soft magnetic characteristics, making it widely used in motor components, electromagnetic parts, and magnetic shielding applications. Its magnetic properties, such as magnetic flux density and coercive force, can be further enhanced through magnetic annealing after cold working.

Difference between SUYP and SUYB
The suffix indicates the product shape:

• P = Plate / Sheet / Strip (e.g., SUYP-1)
• B = Bar / Wire (e.g., SUYB-1)

Example: SUYP-1 means SUY-1 supplied in plate, sheet, or strip form

Exceptional Magnetic Performance

SUY-1 stands out for its superior magnetic properties, thanks to its high purity and soft magnetic characteristics. It is engineered specifically for electromagnetic components, improving performance and efficiency in various industries. This grade is the material of choice for critical applications requiring precise magnetic conductance.


Versatile Forms and Surface Options

Available in coils, sheets, and bars, SUY-1 adapts to a broad range of design requirements. Its surface can be supplied in both bright and dull finishes, allowing for customization based on end-use needs. The offered dimensional range ensures suitability for both small-scale and large industrial projects.


Ideal for Deep Drawing and Coining

The annealed and rolled tempers of SUY-1 provide excellent formability, making it highly recommended for deep drawing and coining operations. This formability ensures that components can be manufactured with reduced risk of cracking or failure, resulting in reliable and consistent product quality.

FAQ's of SUY-1 | Soft Magnetic Iron (Pure Iron):

Q: How is SUY-1 soft magnetic iron commonly used in industry?

A:SUY-1 is extensively used in the manufacture of electromagnetic components, motor yokes, magnetic shielding plates, and for deep drawing and coining applications due to its excellent magnetic properties and formability.

Q: What are the benefits of choosing SUY-1 for electromagnetic components?

A:The high purity and soft magnetic nature of SUY-1 allow for greater magnetic permeability and minimized core losses, which translate into higher efficiency and performance in electromagnetic devices such as motors and transformers.

Q: When should I select SUY-1 in the annealed temper versus as rolled (hard)?

A:The annealed temper is preferable when superior ductility and ease of forming are needed, such as in deep drawing or coining. As rolled (hard) is selected for applications requiring higher mechanical strength but less complex shaping.

Q: Where is SUY-1 manufactured and how can it be sourced?

A:SUY-1 is manufactured in Japan and is available worldwide through authorized exporters and suppliers, making it accessible for global industrial requirements.

Q: What are the available dimensions and shapes for SUY-1?

A:SUY-1 can be supplied in coils, sheets, or bar shapes, with widths ranging from 3.0 to 300 mm and thicknesses from 0.030 to 2.5 mm, providing flexibility for various applications.

Q: How is the chemical composition of SUY-1 significant for its application?

A:The chemical purity of SUY-1 ensures minimal interference with magnetic properties, making it highly effective for applications where reliable magnetic performance is essential.

Q: What surface finishes are available for SUY-1 and what are their typical uses?

A:SUY-1 is offered in both bright and dull surface finishes. Bright finishes are generally preferred for components where surface appearance and cleanliness are critical, while dull finishes may be chosen for less visible or structural parts.
