Product Overview
The 100 mm Neodymium Block Magnet is a robust Nd‑Fe‑B permanent magnet block designed for industrial applications requiring strong, stable magnetic force in large or heavy constructions. With its large volume and high-grade material, this block magnet suits demanding uses such as motor housings, magnetic chucks, magnetic separators, heavy‑duty fixtures, and industrial automation modules. As a dedicated industrial NdFeB block magnet supplier, we provide both standard sizes and custom‑tailored solutions to meet OEM and system‑integrator needs.
Specifications & Material Properties
- Material: Sintered Nd‑Fe‑B (rare‑earth neodymium‑iron‑boron) - known as the strongest commercially available permanent magnet material.
- Size Reference: 100 × 50 × 25 mm (or other dimensions per request) - large block geometry for high flux density and strong holding power.
- Grade Options: Typical grades N35 through N52 - customers may choose based on needed magnetic strength and operating conditions.
- Surface Finish / Coating: Standard Ni‑Cu‑Ni (nickel‑copper‑nickel) plating for corrosion resistance. Other coatings (zinc, epoxy, etc.) available for projects demanding enhanced environmental protection.
- Magnetization Direction: Configurable - through thickness, length or width depending on application needs. For heavy-duty use, orientation can be optimized for maximal flux in required direction.
- Operating Temperature Range: Standard NdFeB operates up to ~80 °C; higher temperature grades possible for more demanding environments.
Key Features & Applications
- Exceptional Magnetic Force: As a large block magnet, it provides stronger flux than smaller magnets of the same grade, making it effective for heavy equipment, magnetic fixtures, or large assemblies.
- Space‑efficient Strength: Compared with older magnetic materials, NdFeB gives the highest magnetic performance per volume - allowing compact designs without sacrificing force.
- Versatile Integration: Block shape and configurable magnetization directions make it easy to integrate into motor housings, magnetic chucks, separators, electromagnetic assemblies, linear actuators, or industrial machinery.
- Durable & Corrosion‑Resistant: With nickel‑based coating and optional enhanced surface treatment, the magnet resists oxidation - suitable for industrial or semi‑exposed environments.
Why Industrial Buyers Choose Us
- We support bulk order supply and custom magnet solutions - ideal for OEMs, motor manufacturers, automation integrators, and equipment builders needing consistent performance and volume.
- Every batch undergoes strict quality control: magnetic flux, dimensional tolerance, coating integrity. Deliveries include test reports and traceability for procurement and QC purposes.
- We offer flexible customization: changing size, magnetization direction, coating type to match your assembly requirements and environmental constraints.
- Using large block magnets reduces complexity in assembly, lowers component count, and simplifies mechanical design compared with assembling multiple small magnets.
Packaging & Delivery
For safe transport, magnets are packed with non‑magnetic separators to prevent magnetic attraction between items. Bulk shipments are handled with magnet‑safe crates and protective padding. For large orders, we provide palletized packaging with clear batch labeling and documentation to support your inventory management and traceability process.
FAQ
Q1: Can you provide dimensions other than 100 mm standard block?
Yes - under our custom magnet service we accept your drawings or specs and produce blocks in any required size, magnetization direction, and coating.
Q2: What is the typical lead time for bulk orders?
Standard block magnets are usually ready in 2–4 weeks depending on order volume. Custom specs may require longer - we will confirm lead time upon enquiry.
Q3: Is the Ni‑Cu‑Ni coating durable for humid or slightly corrosive environments?
Yes - the standard coating offers solid protection under normal industrial conditions. For tougher environments we can apply epoxy or zinc coatings on request.
Q4: Do you supply test reports for magnetic strength and dimensions?
Absolutely. Each batch includes flux and coercivity tests, dimensional tolerance checks, and coating inspection - suitable for procurement quality assurance and compliance documentation.
