Product Description
24 pieces of 2″ x 1″ x 0.5″ Thick Neodymium NdFeB Block Magnets, Epoxy + Nickel + Copper + Nickel Quadruple Layer Coated with tapered center hole. Tapered counter sunk center hole to recess a screw head. Super strong magnets, suggested by Hugh Piggott’s “How to Build Wind Turbine” book. The combination of Epoxy and Nickel+Copper+Nickel coating is the best solution against both corrosion in salt, acidic conditions and moisture, oxygen. Epoxy + Nickel + Copper + Nickel 4-layer coating has better Corrosion Resistance and excellent adhesion to metal surface than Nickel coating, this coating is best for bonding metal. Epoxy + Nickel + Copper + Nickel 4-layer coating is much more durable than Epoxy single layer … More >>
