Alnico Pot Magnets
The internal threaded mounting pot magnet is a pot magnet that has a threaded hole in the centre of the ferromagnetic mild steel cup and a solid disc magnet inserted inside the cup. The threaded section does not go all the way through the pot magnet - it is only within the mild steel cup section. Pot Magnets for Mounting Applications
Products Description
Introducing our ALNICO Pot Magnets, a versatile and reliable solution for your magnetic holding needs. These pot magnets are crafted using high-quality Alnico magnet material, known for its excellent magnetic properties and durability.
What Are Alnico Pot Magnets?
Alnico pot magnets consist of a high-quality Alnico magnet encapsulated within a steel housing, often referred to as a "pot" or "cup." This design maximizes the magnetic strength while protecting the magnet from mechanical damage, corrosion, and environmental factors. The Alnico alloy, composed of aluminum, nickel, cobalt, and iron, gives these magnets excellent temperature stability and robust magnetic properties, while the steel pot enhances their holding power and durability.
These magnets are typically used in applications where a strong, focused magnetic field is required, and the protective pot helps prevent damage during handling and use.

Products Common Applications
• Sensors & Instrumentation (flow meters, gauges)
• Automotive Systems (speedometers, old-style fuel pumps)
• Industrial Holding (jigs, fixtures, magnetic chucks)
• Aerospace Components (where temperature stability is critical)
Benefits of Using Alnico Pot Magnets
Compact and Strong
Alnico pot magnets provide a compact form factor with a surprisingly strong magnetic force. This allows them to be used in situations where space is limited, yet a powerful magnet is needed to hold or attract objects.
Enhanced Magnetic Focus
The steel pot helps concentrate the magnetic field, allowing for more efficient use of the magnet's energy. This is especially beneficial when the magnet needs to attract or hold a specific object with a precise magnetic field.
Easy to Install and Use
Alnico pot magnets are often designed with a hole or threaded insert in the steel housing, making them easy to mount, install, and remove. This feature adds versatility and makes them user-friendly for various applications.
Versatility Across Industries
Alnico pot magnets are used in a wide range of industries, from manufacturing and construction to electronics and automotive. Their combination of strength, durability, and resistance to environmental factors makes them a go-to choice for many applications.

Selection Considerations
Size vs. Strength: Alnico has lower pull force than neodymium but better temperature stability
Orientation: Axially or diametrically magnetized options available
Mounting: Choose threaded holes, countersunk, or through-bolt configurations
Pro Tip: For high-vibration environments, use epoxy-sealed Alnico pot magnets to prevent internal movement.
Maintenance & Handling
• Avoid mechanical shock - Alnico is brittle
• Store away from strong magnetic fields to prevent accidental demagnetization
• Clean with solvent - No special corrosion protection needed

FAQ
1.What is Alnico Deep Pot Magnets? The application?
Internal threaded mounting pot magnet & deep pot magnet The internal threaded mounting pot magnet is also known as aninternal threaded pot magnet. Deeper or taller versions of the internal threaded mounting pot magnet are sometimes also known as Deep Pot Magnets, although this is rather a loose terminology.
The internal threaded mounting pot magnet or deep pot magnet are very popular in clamping applications because you can simply bolt them onto your assembly. The larger units provide very powerful clamping forces, with the mild steel outer cup providing protection and mechanical strength to the pot magnet and inner magnet. Because the mild steel is threaded, reasonably high torque can be applied to securely hold the pot magnet in place.

2.How to Choosing the Right Alnico Pot Magnet
When selecting an Alnico pot magnet for your application, consider the following factors:
Magnetic Strength: Ensure that the pull force of the magnet is suitable for your needs. Pot magnets can vary widely in terms of strength, so choose one that matches the weight or force required by your application.
Size and Shape: Pot magnets come in various sizes, from small magnets used for light holding to large magnets designed for heavy-duty industrial lifting. Consider the dimensions of the space where the magnet will be installed.
Temperature Requirements: If your application involves high-temperature environments, make sure to choose a pot magnet rated for high heat stability.
Environmental Considerations: If the magnet will be exposed to harsh conditions, such as moisture, chemicals, or outdoor weather, select a model with appropriate corrosion resistance.
