What You Need to Know About Pot Magnets?


To have a deep understanding of pot magnets, we need to master a series of related knowledge. First, we need to understand the basic principles of magnetism, including the generation of magnetic fields and the properties of magnets. Secondly, we should study the structure, manufacturing process and use of pot magnets, as well as its applications in different fields. Finally, we also need to understand the key role of pot magnets in scientific research and engineering practice. This article will introduce these knowledge points step by step to help you understand pot magnets more comprehensively.


How pot magnets are made?

The production process of pot magnets is very complex and involves precision alloy materials and processes. First, the smelting method is usually used to mix magnetic elements such as iron, nickel, and cobalt with other alloying elements to form the desired alloy. Next, this alloy is melted and cast into the shape of a pot magnet through injection molding, extrusion or other methods. It is then cooled and precision ground to obtain the required dimensions and magnetic properties. Finally, the magnet may require further processing, such as magnetization, to ensure it has the required magnetic properties.


Are pot metals more magnetic?

Pot metal is generally more magnetic than regular steel because its alloy contains more elements such as iron, nickel and cobalt, which play a key role in generating strong magnetic fields. Therefore, for the same size, pot metal magnets are generally capable of producing stronger magnetic fields, making them very useful in many applications.


Is the pot metal magnetized?

Yes, pot metal can be magnetized. They can be magnetized by exposing them to an external magnetic field, or by conducting an electric current. Once magnetized, pot metals will retain some degree of permanent magnetism, making them ideal for making a variety of magnetic devices and tools.


Is the pot metal sturdy?

Pot metals generally have high hardness and wear resistance, which makes them relatively strong. They can resist some wear and corrosion, making them excellent in some applications where strength and durability are required. This makes pot metal ideal for making magnetic tools, magnetic clasps, and other durable magnetic products.


Are pot metals still in use?

Yes, pot metal is still widely used in a variety of applications. They play key roles in motors, generators, sensors, medical devices and other fields. Due to its high magnetism and adjustability, pot metal remains one of the indispensable materials in modern technology and engineering.


Can pot metal be welded?

Pot metal is often relatively difficult to weld because its alloy composition is not friendly enough to general welding methods. However, some special welding techniques, such as cobalt-based brazing, can be used to achieve pot metal welding. This requires expertise and technology to ensure that the magnetic properties after welding are not negatively affected.


The difference between deep pot magnets and shallow pot magnets

Deep pot magnets and shallow pot magnets are two different shapes and sizes of magnets that differ in their magnetic properties and uses. Here are the main differences between deep pot magnets and shallow pot magnets:

Magnetic pole depth:

Deep pot magnets have a deeper magnetic pole structure and the magnetic field strength is distributed over a larger depth range.

Shallow pot magnets have a shallower pole structure and the magnetic field strength is distributed over a shallower depth range.

Magnetic field strength:

A deep pot magnet is typically capable of producing a stronger magnetic field due to its deep magnetic field distribution.

Shallow pot magnets have a relatively shallow magnetic field and therefore generally produce a weaker magnetic field.


Deep pot magnets are commonly used in applications that require deep penetration and strong magnetic fields, such as motors, generators, magnetic absorbers, etc.

Shallow pot magnets are typically used in applications that require shallower magnetic fields, such as magnetic buckles, sensors, magnetic clamps, etc.

Size and shape:

Deep pot magnets typically have larger sizes and complex shapes to accommodate the deep pole structure.

Shallow pot magnets are typically small and relatively simple in shape to accommodate shallow magnetic field distribution.

Manufacturing difficulty:

Manufacturing deep pot magnets generally requires a more complex process because their deep pole structures require greater engineering precision.

Shallow pot magnets are relatively easy to manufacture because their pole structures are shallow and the process requirements are low.

Deep pot magnets and shallow pot magnets differ in their magnetic properties and applications, and choosing the right type based on specific needs is critical for different engineering and technical applications.


Pot Magnet: Core Material

The magnetic force depends on the material of the core. The cheapest but also weakest variant is the ferrite magnet. Ferrite magnets, on the other hand, are very strong and corrosion-resistant, so they can be used outdoors as well.

High energy magnets include neodymium magnets and samarium cobalt magnets. They are typically used where very high holding power or adhesion is required and in smaller sizes. Both variants are rare earth alloys. Samarium cobalt magnets can be used at very high and very low temperatures and are more corrosion resistant than neodymium magnets. Because its raw material reserves are limited, it is more expensive. NdFeB magnets are less brittle.

Certain safety precautions are required when handling high-energy magnets. For example, never use them near children.


Different attachment options for magnetic basins

You can buy can magnets in different mounting styles:

- Countersunk head pot magnet

There is a continuous hole with internal threads in the middle. If you still have a countersunk hole, using a suitable countersunk screw won't protrude anything.

- Tank shape with threaded bushing

A magnet with a non-continuous threaded socket on the back of the magnet is screwed onto a pin with external threads. There are also variations with threaded pins for screwing into sockets.

If none of these mounting options are available, magnets can also be glued into the appropriate openings. Various versions have a hook or eyelet on the non-adhesive side for easy and flexible attachment to metal surfaces.

Other models and accessories for pot magnets with or without threads

The magnetic core is installed in a steel pot or stainless steel pot. Steel will produce a slightly higher bond. Stainless steel is rust-resistant and therefore suitable for outdoor use as well. Other possible uses stem from the way the casing is made. It can be a turned or pressed shell. Because turning is more complex, the pot can be made more precisely. Rubber disks and rubber caps are also available as accessories for can magnets. They protect sensitive surfaces from scratches.

Can magnets are also known as deep can magnets, mounting magnets, fastening magnets or clamping magnets. With them, the magnetic core is integrated into a round steel pot. The resulting magnetic short circuit increases the magnetic flow and thus the adhesion force. This magnet gets its name from its very low design.


What is the difference between pot magnets?

Can magnets are easy to securely attach, lift or hold and are ideal for removable connections - not just for metal, factory, trade show or shop construction. Deep pot magnets are great for holding objects securely to metal surfaces.

Pot magnets are available with neodymium magnets and ferrite cores with threaded bushings, countersunk or cylindrical holes, or external threads. As counterparts to pot magnets on non-metallic surfaces, you can also get screwed and glued metal discs from us.


Buying Pot Magnets: All the Advantages in Brief

Can magnets have many advantages. Here is an overview of the most important:

- Can magnets have strong adhesion despite their flat design

- Depending on the material, they can also be used in high temperatures and adverse weather conditions

- Pure metal and rubber pot magnets - For example, you can use pot magnets with eyelets or hooks for magnet fishing

- Our H&Z magnets are almost impossible to demagnetize - only strong electromagnets can be used

- All pot magnets are available in different versions



A can magnet is a versatile tool that can be used in a variety of applications. They are stronger, more durable, safer and easier to use than traditional magnets. If you're looking for a magnet to help you complete a task, a pot magnet is a great choice.
