Strong and durable

Very powerful magnets. I deducted one star only because the packaging could be better to prevent them from clanking during shipping, but the product itself is flawless.

Great value, handle with care

Excellent magnetic strength for the price. Just be careful when separating them as they can snap together quickly. Overall a great purchase.

Industrial grade quality

We use these in our production line for temporary fixture holding. They have maintained their strength over months of daily use. Highly recommend.

Incredibly strong hold

These magnets are exactly what I needed for my workshop jig. The pull force is impressive even on thick steel plates. Very satisfied with the quality.

Perfect for DIY crafts

I used these to make custom cabinet latches. They are small but mighty. The nickel coating looks professional and hasn't chipped yet.

Exceeded expectations

The rectangular shape makes them easy to mount compared to round discs. The adhesive backing option would be nice, but the raw magnet works perfectly for our bolts.

5 FAQ

Q: Do these come with adhesive backing?

A: This specific listing is for the raw magnet blocks without adhesive. However, you can easily attach them using strong epoxy glue or double-sided industrial tape.

Q: What is the exact pulling force of a single magnet?

A: The pulling force varies based on the surface thickness and material, but for a direct pull on a thick steel plate, a single N52 block of this size typically holds around 15-20 lbs.

Q: Are these magnets suitable for outdoor use?

A: Yes, the Ni-Cu-Ni coating provides good corrosion resistance, but for prolonged exposure to harsh weather, we recommend adding an additional protective sealant.

Q: Will the magnet lose strength over time?

A: Neodymium magnets are permanent magnets and will retain over 99% of their strength for decades, provided they are not exposed to temperatures above 80°C or physical damage.

Q: Can these be drilled or cut to size?

A: We strongly advise against drilling or cutting these magnets yourself. The material is brittle and can crack or shatter, and the dust generated is flammable. Please order custom sizes if needed.
