Understanding Magnetism: How Metal Surfaces Affect Magnetic Strength

At Equihook, we pride ourselves on the quality and strength of our magnetic bridle hooks. Our hooks use powerful magnets with a pulling force of 20kg, capable of holding up to 6kg on suitable metal surfaces. However, it’s important to understand that not all metal surfaces are the same, and this can affect the performance of the magnets. Here’s a quick guide to help you understand how different metals interact with magnets:

1. Ferromagnetic Metals: The Best Choice

Ferromagnetic metals like iron, steel, and nickel are ideal for magnetic hooks. These metals have high magnetic permeability, meaning they easily allow magnetic lines of force to pass through them. As a result, our bridle hooks will perform optimally on these surfaces, providing a strong and secure hold.

• Examples: Steel barn doors, wash box posts, stable door & gate furniture, non aluminium lorry partitions, and metal stable walls/dividers.

2. Stainless Steel: Varies by Type

Stainless steel can be tricky because it comes in various grades, some of which are magnetic and others are not. Generally, stainless steel with high chromium content and low nickel content (like 400 series stainless steels) is magnetic and will work well with our hooks. In contrast, 300 series stainless steels, which have higher nickel content, are typically not magnetic.

• Note: If you’re unsure about your stainless steel surface, a simple way to test its magnetism is to use a fridge magnet. If it sticks, our hooks should work well.

3. Non-Ferromagnetic Metals: Less Effective

Metals like aluminum, brass, copper, and zinc are non-ferromagnetic. This means our hooks will have a much weaker hold on these surfaces. If you need to use our hooks on these materials, consider adding a ferromagnetic plate or strip to the mounting area.

• Examples: Aluminum stall doors, brass fittings.

Tips for Optimal Use

• Ensure Clean Surfaces: For the best performance, make sure the metal surface is clean and free from dust or debris.
• Check Surface Thickness: Thicker metal surfaces usually provide better magnetic hold. Thin metal sheets might not support the weight as effectively.
• Use Ferromagnetic Strips: For surfaces where magnetic hold is insufficient, consider adding a ferromagnetic plate or strip to the mounting area to enhance the magnetic grip.
