WIND TURBINE GENERATOR MAGNETS – 24PCS 2X1X1/2″ RARE EARTH NEODYMIUM BLOCKS N42 WITH TAPERED COUNTER SINK HOLE, EPOXY-NI-CU-NI COATED
Feb 24th
- Top Quality Grade N42 Neodymium Iron Boron (NDFeB) Rare Earth Magnets
- Strong and Powerful, much stronger than ceramic magnets
- 2″ long x 1″ wide x 1/2″ thick with taper hole, magnetized through thickness
- Quantity: 24 magnets per package
- 1/8″ Diameter counter sunk center hole fits with #6 metal screws
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 >>
