Product Description
Neodymium Magnets N42 Block Epoxy+Ni 2 in x 1 in x 1/2 in
Neodymium Magnets N42 Block 2 in x 1 in x 0.5 in – High-Performance Rare Earth Magnet with Epoxy + Copper + Nickel Triple Coating for Wind Turbines, Fixtures, and Industrial Use
Designed for durability in harsh environments, this N42 neodymium block magnet features an advanced Epoxy + Copper + Nickel triple-layer. This advanced Epoxy + Copper + Nickel triple-layer coating is engineered for enhanced corrosion resistance, based on industry-standard salt spray testing practices. Its high-grade N42 material makes it ideal for wind turbine projects, industrial fixtures, and custom assemblies requiring long-term performance and stability while delivering strong, reliable magnetic force up to 80°C (176°F).
Key Features:
- High-Performance Rare Earth Magnet: 2" (L) x 1" (W) x 0.5" (T) block size provides a compact yet powerful magnetic solution.
- Strong N42 Grade: Recommended by Hugh Piggott’s “A Wind Turbine Recipe Book” for high-performance wind generator builds, offering superior strength over N35, N38, and N40 grades.
- Triple-Layer Epoxy + Copper + Nickel Coating: Engineered for enhanced corrosion resistance and adhesion; triple-layer design helps extend magnet lifespan in moist and outdoor environments.
- BrMax: 13,200 Gauss for strong and stable performance.
- Approximate Pull Force: 72 lbs under ideal conditions for heavy-duty applications.
- Magnetized Through Thickness: North and south poles on the 2"x1" surfaces for reliable contact and alignment.
Built for Long-Term Durability in Harsh Conditions
This N42 neodymium magnet with Epoxy + Copper + Nickel triple coating offers superior protection against corrosion, cracking, and chipping, making it the ideal choice for wind generator magnets, outdoor magnetic fixtures, and industrial applications where durability is critical.
Unlike magnets with inferior single-layer epoxy coatings that can easily fail, this advanced triple-layer system ensures maximum performance and lifespan, even in coastal or humid environments.
Common Applications:
- Wind generator magnets and renewable energy projects
- Magnetic fixtures and jigs for outdoor use
- Industrial machinery holding and retrieval systems
- Heavy-duty bonding and alignment in fabrication projects
- Educational and science kits requiring durable, high-strength magnets

Frequently Asked Questions (FAQ)
Why choose the Epoxy + Copper + Nickel coating?
This advanced triple coating offers superior corrosion resistance and durability, ensuring your magnets withstand harsh environments and heavy use without performance loss.
Is this magnet suitable for wind turbines?
Yes. It is recommended in Hugh Piggott’s book for wind turbine builds, providing the strength and corrosion resistance needed for high-performance renewable energy projects.
Can it be used outdoors?
Yes, the advanced triple coating provides excellent protection in moisture-prone, coastal, or humid environments.
How should I handle this magnet safely?
These magnets are very powerful; handle with caution to avoid pinching and keep away from electronics, pacemakers, and sensitive devices.
What is the maximum temperature this magnet can withstand?
This N42 magnet is rated up to 80°C (176°F). Higher temperatures may cause permanent loss of magnetic strength, and epoxy coatings may degrade faster in elevated or fluctuating thermal conditions.
Maximum Durability and Strength for Demanding Applications
Whether you are building a wind generator, developing industrial fixtures, or designing high-performance assemblies, this N42 neodymium block magnet with Epoxy + Copper + Nickel triple coating delivers the strength, stability, and corrosion resistance you need for long-term, reliable results.
