Specifications

The n52 20x20x5mm block neodymium magnet has various specifications that make it ideal for different industrial applications. These include its magnetic strength, size, orientation, and tolerance.

• Dimensions: The neodymium magnet measures 20 mm by 20 mm by 5 mm. This translates to 2 cm by 2 cm by 0.5 cm. The block shape enables easy handling and installation.
• Magnetic strength: The N52 grade gives the magnet its strongest possible magnetic field. The magnetic surface field can reach 1450 to 1600 Gauss, thus ensuring optimum performance in any application.
• Magnetization orientation: The N52 magnet is typically oriented through the thickness. This boosts its magnetic pull across the larger 20 mm surfaces.
• Tolerance: Neodymium magnet attracts metallic substances. This may cause unintentional attraction across the entire magnet surface. It also has a typical tolerance of +/- 0.1 mm on each dimension. This ensures precision for applications requiring stringent dimensional adherence.
• Coating: N52 block magnets have electroplated Ni-Cu-Ni coating for optimal corrosion resistance. Nickel, copper, and nickel are the three coats for corrosion prevention.
• Max operating temperature: The N52 neodymium magnet can operate optimally at a maximum temperature of 80°C (176°F). Beyond this point, the magnet risks losing its magnetic strength.

How To Choose

Buyers on Cooig.com can consider the following factors when purchasing N52 block neodymium magnets in bulk:

• Material: N52 20x20x5mm block neodymium magnets are made from an alloy of neodymium, iron, and boron. This gives it the characteristic strong magnetic pull. Buyers should ensure they purchase the N52 grade to enjoy the strongest possible magnetism that this alloy can create.
• Size: Buy N52 block magnets of the specified size (20x20x5mm). Larger magnets can be cut to size, but this can be difficult. Ensure the seller has the size from stock. Confirm that the seller has a uniform size across all batches. The block shape allows easy handling and installation.
• Coating material: N52 neodymium magnets are prone to corrosion. They have electroplated Ni-Cu-Ni coating for optimal corrosion resistance. This also ensures the magnet lasts longer when used indoors and outdoors. Buyers should ensure the coating is electroplated nickel-copper-nickel for maximum durability.
• Magnetization orientation: This boosts its magnetic pull across the larger 20 mm surfaces. N52 magnets are typically oriented through the thickness. Confirm this orientation with the seller before purchase.
• Quality check<: Confirm that the seller has quality checks to ensure the tolerance is usually +/-0.1mm on each dimension. This guarantees precision for applications that require stringent dimensional adherence.
• Temperature resistance: Check that the neodymium magnets can withstand temperatures of up to 80°C (176°F). This ensures the magnets do not demagnetize during or after the industrial application.
• Wholesale rewards: Buyers should shop for more than one kind of neodymium magnet and at bulk quantities to enjoy special discounts.

How To Use

Businesses can use 20x20x5 mm block N52 neodymium magnets to hold objects in industrial applications. The N52 is the grade of neodymium magnet with the strongest possible magnetic force. Users should first ensure that the surface to which the magnet will attach is clean and dry. This ensures a strong hold without slipping or sliding.

These magnets are often used in metal surfaces. By holding the object in place, N52 magnets enhance the accuracy of tasks performed around it. In machines, users place the magnet on a workstation where components frequently need to be held.

In assembly lines, N52 magnets can help in transporting parts from one station to another. They boost efficiency by minimizing the manual handling of parts during transport.

Users in workshops use N52 magnets to organize tools and parts. This leaves workbenches clutter-free, improving productivity. Further, businesses in shipping temporarily use these magnets to secure packages that are being transported.

In robotics, N52 block magnets help in parts pick-and-place applications. They are integrated into robotic arms to enhance their functionality.

Around the office, these magnets are used as name holders in events. This makes them stylish and functional. In advertising, businesses attractively mount posters, signs, and banners using these N52 magnets in a visually appealing manner.

Finally, these magnets are popular in product design. Businesses use them in prototypes containing magnetic components.

Q & A

Q1. Are n52 block magnets suitable for outdoor use?

A1. Yes, they are. These block magnets have a coating of electroplated Ni-Cu-Ni for optimal corrosion resistance. Users should note that although the coating offers excellent protection against rust and corrosion, prolonged exposure to harsh outdoor elements may gradually wear the coating.

Q2. What are the recommended storage methods for N52 block magnets?

A2. Users are advised to store these magnets in a dry and cool environment, ideally at room temperature. They should keep them away from direct sunlight, as this may affect the coating. Further, users should stack them using ferromagnetic spacers between the magnets to prevent them from chipping or scratching.

Q3. Can block N52 magnets attract large metallic objects?

A3. Yes, they can. The N52 block magnets are designed to have a powerful magnetic hold. This enables them to attract and stick to large metallic objects. However, the strength with which the magnet holds will depend on multiple factors. These include the size, thickness, and material type of the magnet and object. Additionally, the magnetic surface area contact, object orientation, and environmental vibration will also affect the hold.

Q4. Do block N52 magnets lose their magnetism with time?

A4. No, they don’t. Neodymium magnets are designed to last several years and even decades under optimal storage conditions. However, conditions such as extreme heat exposure, direct sunlight, and physical damage may cause loss of magnetism over time. N52 is the strongest magnet. Assuming all conditions are optimal, it can last up to 100 years.

Q5. Can N52 block magnets be stacked to increase their magnetic strength?

A5. Yes, they can. Stacking N52 block magnets increases their magnetic strength. However, they should be separated by small, non-magnetic spacers. These allow the magnetic fields to interact. Users should avoid stacking them directly against one another. This will result in fields cancelling each other out.
