Product Overview
For industrial applications, motor parts, magnetic fixtures, sensor modules, and bespoke assemblies, our N35–N52 Neodymium Iron Boron Bar Magnet provides dependable, high-energy magnetic performance in a rectangular bar shape. This magnet bar, which is made from sintered Nd-Fe-B material and comes in a variety of grades, is a popular option for OEMs, producers of automation equipment, and mechanical engineers involved in magnetic design because it offers a strong magnetic flux for steady performance.
Specifications
- Material: Sintered Nd-Fe-B (Neodymium-Iron-Boron)
- Available Grades: N35 through N52 - choose based on energy and coercivity requirements.
- Shape: Rectangular bar / block - size customizable per your drawing or requirement
- Coating / Surface Finish: Standard Ni-Cu-Ni nickel plating; other coatings (zinc, epoxy, etc.) available on demand for corrosion resistance.
- Magnetization Direction: Axial (through thickness) or tailored magnetization per request - suitable for magnetic circuits, assemblies or modules needing directional flux.
- Density & Physical Properties: Typical NdFeB density ~7.5 g/cm³; magnet energy product and coercivity vary by grade - higher grades (e.g. N52) offer higher magnetic energy but may have lower max working temperature compared with lower grades.
Key Features & Industrial Applications
- High Magnetic Energy in Compact Form: Even relatively small bar magnets from this series provide strong magnetic flux, suitable for motors, actuators, magnetic clamps, fixture modules, or any device where space is limited but force is needed.
- Flexible Integration: The bar shape is easier to align, fix or embed in housings, mechanical frames, or assemblies - saves machining or fixture design work for OEMs.
- Custom Magnet Solutions: We support bulk order and custom magnet requests - whether you need special dimensions, magnetization patterns, or coating for harsh environments.
- Wide Use Cases: Common applications include - permanent magnet motors (rotor/stator inserts), magnetic fixtures/clamps, magnetic sensors, magnetic couplings, magnetic assemblies in automation equipment, linear actuators, and magnetic modules for tools or devices.
Advantages for Buyers / OEMs
- Consistent Bulk Supply: Thanks to standardized grades (N35–N52) and strict production control, we deliver magnets with stable performance and tight tolerances across batches - ideal for large-volume manufacturing.
- Tailored Customization: If your design demands non-standard size, shape or magnetization, simply send your drawings - we offer custom bar magnet production to meet your exact needs.
- Cost-Effective Integration: Using a bar magnet reduces material waste compared to cutting from larger blocks or rings, and simplifies assembly work for fast production cycles.
- Coating & Durability Options: For corrosive or humid environments, epoxy or zinc coatings can be provided - suitable for industrial machinery, outdoor equipment, or applications exposed to moisture.
Quality Assurance & Service
Every magnet batch is tested for magnetic flux, residual induction, and dimensional accuracy. Coating adhesion and surface finish are inspected to ensure reliability for industrial use. For bulk clients, we provide inspection reports and batch traceability, supporting QC and audit requirements.
We also offer pre-production samples, design consultation for magnet layout, and flexible MOQ for small-batch prototyping - enabling you to validate performance before full-scale production.
FAQ
Q1: Can you produce bar magnets in custom sizes or grades other than N35–N52?
Yes, we accept customer drawings and produce custom bar magnets with different sizes, magnetization directions, grades and coatings as needed.
Q2: What is the typical lead time for bulk or custom orders?
Standard sizes: 7–14 days. Custom sizes or coatings may take longer depending on production schedule and volume.
Q3: Is nickel plating sufficient for humid or corrosive environments?
For general industrial use nickel plating works well. For more demanding environments (chemicals, high humidity), we recommend epoxy or zinc coatings - we offer these options on request.
Q4: Can you supply magnetic performance test reports for each batch?
Yes - we provide test data (Br, coercivity, etc.), dimensional inspection, and coating check results with each shipment, supporting your quality control and traceability needs.
