Flexible Rubber Magnets

Flexible rubber magnets are a versatile and cost-effective type of permanent magnet made from a mixture of ferrite powder and rubber or plastic binders. They are commonly supplied in sheets, strips, rolls, and custom shapes.

Unlike rigid magnets such as neodymium or ferrite blocks, rubber magnets are flexible, lightweight, and easy to cut or convert into custom products. This makes them ideal for signage, displays, printing, and general-purpose applications.

At Aussie Magnets we supply a wide range of flexible rubber magnets, including isotropic and semi-isotropic materials, and can manufacture custom sizes, shapes, and finishes to suit your application.

What Are Flexible Rubber Magnets?

Flexible rubber magnets are made by combining ferrite magnetic powder with a flexible binder such as rubber or plastic. The material is then rolled or extruded into sheets or strips.

This manufacturing process produces a magnet that is:

Flexible and bendable
Lightweight
Easy to cut or shape
Available with adhesive backing or printable surfaces

These magnets are widely used in commercial, industrial, and promotional applications.

Isotropic vs Semi-Isotropic Rubber Magnets

Flexible rubber magnets are typically available in two main types: isotropic and semi-isotropic materials.

Isotropic rubber magnets – the most common type, with a lower magnetic strength but excellent flexibility and cost efficiency. These can be magnetised in multiple directions and are ideal for general-purpose applications.
Semi-isotropic rubber magnets – offer improved magnetic performance compared to standard isotropic material, while still maintaining flexibility. These are used where slightly higher holding force is required.

Choosing between isotropic and semi-isotropic depends on the required holding strength, application, and budget.

How Strong Are Rubber Magnets?

Flexible rubber magnets provide lower magnetic strength compared to neodymium or solid ferrite magnets. However, they offer sufficient holding force for many applications, especially where large surface area contact is used.

Their performance depends on:

Material type (isotropic or semi-isotropic)
Thickness of the magnet
Surface contact area
Air gap between surfaces

Increasing thickness and surface area will improve overall holding strength.

Common Uses for Flexible Rubber Magnets

Rubber magnets are widely used in both commercial and everyday applications due to their flexibility and ease of use.

Fridge magnets and promotional products
Magnetic signage and vehicle graphics
Magnetic sheets for printing
Craft and hobby projects
Warehouse labelling and displays
Flexible magnetic strips for sealing or holding

They are especially useful where magnets need to conform to curved surfaces or be easily removable.

Advantages of Flexible Rubber Magnets

Flexible and easy to cut or shape
Lightweight and easy to handle
Cost-effective for large-area applications
Available with adhesive backing or printable surfaces
Suitable for custom manufacturing

Limitations of Flexible Rubber Magnets

While rubber magnets are highly versatile, they are not suitable for applications requiring high magnetic strength.

Lower magnetic strength than rigid magnets
Not suitable for heavy-duty holding applications
Performance depends heavily on surface contact area

For applications requiring strong holding force in a compact size, neodymium magnets are usually a better choice.

Custom Rubber Magnet Manufacturing

Flexible rubber magnets are highly adaptable and can be manufactured in a wide range of formats to suit specific applications.

Custom sheet sizes and thicknesses
Die-cut shapes
Adhesive-backed magnets
Printable or laminated surfaces
Magnetisation patterns to suit application requirements

At Aussie Magnets, we can manufacture and supply flexible rubber magnets to meet custom specifications, whether for industrial use, signage, or promotional applications.
