PVC Waterproof Magnets, Unbreakable Plastic-Coated N52 Neodymium Disc Magnets, Waterproof Strong Permanent NdFeB Rare Earth Magnets Coated with Hard Polypropylene

PVC Waterproof Magnets Product features
UNBREAKABLE -Thick Polypropylene coating can withstand falls, collisions with other magnets, strikes and more. Nickel-Copper-Nickel surface plating protects the magnetic interior and prevents corrosion.
POWERFUL – N52 is the highest grade of magnet in the world. Each magnet has a pulling force of 12 pounds. Magnets will repel/pull each other from over 2 inches apart.
EASE OF SEPARATION – Polypropylene surface provides grip to aid in separation if magnets become stuck to one another.

PVC Waterproof Magnets

GARAGE OR WORKSHOP – Hang tools, drawings or photos from your work bench, toolbox, or other steel objects. Can use to find studs, clean up nails or metal shavings.
UTILITY – Waterproof, can be used to hang kitchen utensils, gadgets and devices on refrigerators, file cabinets or cupboards. Can also use for fishing, retrieving objects from drains, collecting sewing pins or preventing trash bag sagging. The applications are limitless

Neodymium magnets are the strongest magnets in the world but they are also very fragile. With the MPCO neodymium magnets you no longer have to sacrifice durability for strength. These permanent disc magnets have a thick and hard Polypropylene (plastic) outermost coating that ensures they will not break or chip under the most extreme conditions.

Magnet Size: 1.3 inch (33 mm) diameter, 1/8 inch (3.175 mm) thickness.
Magnet Size With Polypropylene Coating: 1.38 inch (35 mm) diameter, .205 inch (5.175 mm) thickness.
Materials: Neodymium, Iron, Boron, Polypropylene, Nickel, Copper.
Strength 12 pounds, 1,366 Gauss. Pulling force is for a perfect interface with a flat steel surface. Other objects and shapes will result in a decreased pulling force. Magnets will exert a force on each other from over 2 inches away.
Magnetization: Axially magnetized, with N and S poles on flat surfaces.
Polypropylene Coating: .04 inches (1 mm).
Nickel-Copper-Nickel Coating: 15 – 30 um .
Weight: Each magnet weights 22.5 grams.

Destructive Testing:

Collision Smash
To demonstrate strength, two conventional neodymium magnets were allowed to attract (smash) into each other from about a 6 inches away. This image compares conventional neodymium magnets to the unbreakable magnets.

First Hammer Strike
A new victim was selected to receive hammer blows. The two strikes were done with a force a little greater than that used for pounding nails. This image was taken after the first hammer strike.

Second Hammer Strike
This image was taken after the second hammer blow. After the second hammer blow, a crack was formed, however the magnet survived.
