Material Guides

Bunting Material Guides

Choose the right magnet by matching grade family, operating temperature, coating, shape, and assembly style to the job. These guides translate magnetic material tradeoffs into language purchasing, engineering, and maintenance teams can use together.

Bunting's material guide approach is simple: start with the application, then choose the magnet. A high pull-force number on a flat test plate can be misleading when the real installation includes air gaps, curved targets, vibration, washdown, heat, or repeated handling. The better path is to compare families and coatings in context, then document the reason behind the selected grade so the next reorder is easier.

Three decisions that shape a useful magnet specification.

01

Choose the material family

Neodymium offers compact strength, ferrite supports cost-aware and corrosion-friendly uses, and samarium cobalt helps when heat stability is the deciding factor. The family should follow the task rather than the other way around.

02

Define the environment

Humidity, washdown, abrasion, temperature, outdoor exposure, and chemical contact can change the right answer. Coating and housing choices often protect the investment more than moving to a stronger grade.

03

Document the assembly path

Magnetization direction, pole layout, fastener style, spacing, and release method all influence performance. A short drawing note can prevent a future reorder from becoming a fresh engineering investigation.

Use the guide, then ask a human.

If the application has heat, washdown, motion, a small footprint, or a safety concern, Bunting can help turn the guide into a project-specific recommendation.
