ALB Materials Neodymium Magnet, N48 Grade, 20×10×3 mm, Strong Rare-Earth Rectangular Block

This is a sintered neodymium-iron-boron (NdFeB) rectangular magnet, measuring 20 mm in length, 10 mm in width, and 3 mm in height. It’s coated with Ni‑Cu‑Ni (nickel-copper-nickel) for corrosion resistance and durability. The magnet is magnetized through its thickness (axial direction), providing a powerful pull force (~3.4 kg / 7.48 lb) when attached to mild steel. With grade N48

Key Features:

• N48 grade neodymium magnet delivers high magnetic strength in compact form
• Rectangular dimensions: 20 × 10 × 3 mm with smooth nickel-coated finish
• Excellent resistance to demagnetization with strong coercivity and energy product
• Suitable for industrial applications, magnetic sensors, crafts, and R&D setups
• Thin and flat profile ideal for flush mounting or narrow enclosures
• Durable triple-layer Ni-Cu-Ni plating for corrosion resistance and long lifespan
