What factors affect the price of magnets?Why are the quotations of magnets of the same material different?Many novice buyers will have many such questions, and now I will answer them in detail.

The quotation of magnets mainly depends on three factors, the purchase quantity, the specification shape, and the tolerance. The smaller the quantity, the higher the quotation; the more complex the shape, the higher the processing cost; the stricter the tolerance requirements, the higher the processing cost.

Obviously, different materials will naturally affect the price. Usually, the price of NdFeB is definitely higher than that of ferrite. In addition, NdFeB is not corrosion-resistant, and usually needs to be protected by coating. Common coatings are nickel plating, zinc plating, epoxy resin. Choosing a good coating is another cost.

Another example is sintered NdFeB, the price will change with the temperature requirements, the higher the performance, the higher the price.

Finally, and most importantly, the price of magnet raw materials has also been fluctuating.

If you have more questions, feel free to leave us a message, we look forward to communicating with you.

If you've ever purchased a NdFeB magnet, you surely know that almost all NdFeB magnets have a coating, so why don't ferrite magnets need a coating?

First of all, let us know about ferrite magnets, which are non- metallic magnetic materials, also known as magnetic ceramics, so there is basically no corrosion problem. It can be seen everywhere in life. For example, the speaker magnet in the radio is a ferrite magnet.

The magnetic performance of ferrite is not high. It is hard and brittle, but at the same time, it has many advantages,it is not easy to demagnetize, not easy to corrode, and it is cheap.

Similar to ceramics, it is generally formed by molds and sintered, and it is difficult to be machined, so most ferrite products have simple shapes and large dimensional tolerances.

Surface magnetism, also known as surface magnetic field, refers to the magnetic induction intensity at a

certain point on the surface of the magnet, and the unit is Gauss Gs or Tesla T (1T=10000Gs).

The parameter of surface magnetism is easy to measure. When the size of the magnet is determined, people

often judge the performance of the magnet by comparing the surface magnetism. When encountering some

magnets that are not suitable for routine measurement, particularly large or small, and special shapes,surface  magnetic measurement is particularly important.

But we need to know that the surface magnetism is the value measured by the Gauss meter in contact with a certain point on the surface of the magnet. The measurement point does not cover the entire surface of the product. The surface magnetism of different positions on the surface of the magnet is different, so take a certain point The value to measure the value of the entire face is incorrect For non-multipole magnetized and regular-shaped magnets, the central surface magnetism is generally measured.

The surface magnetism is easily affected by the external environment. When measured in different environments, the measured surface magnetism may be different. For the same magnet, using Gaussmeters from different manufacturers, the measured central surface magnetism may be different. The central surface magnetism of the N pole and S pole of the same magnet is also different. And don't forget that every gauss meter has an error of around 2%. 

It can be seen that the surface magnetic measurement is not objective, and it is not a parameter that can fully reflect the performance of the magnet. Therefore, it is usually not recommended as an evaluation indicator for product transactions.

We have been trading in the magnet industry for many years. A small number of customers indicated that the magnetic force of the permanent magnets they purchased was attenuated, and they usually suspected that it was the quality of the product itself. In fact, the quality of our products can stand the test of the market.Today let’s take a look at what factors lead to demagnetization of permanent magnets:

1. Mechanical vibration and impact cause demagnetization.

2. High temperature demagnetization, the increase in use temperature will cause the magnet to demagnetize.

3. The change of the external current magnetic field causes demagnetization.

4. External magnetic field interference causes demagnetization.

In prototype manufacturing, surface finishing plays a crucial role in determining the final product’s aesthetics, functionality, and durability. While the primary goal of prototyping is to validate design concepts and test functionality, surface treatment ensures that the prototype closely resembles the end product in terms of appearance and performance.  

 

 Enhancing Aesthetics and Functionality  

 

Surface finishing techniques, such as painting, anodizing, sandblasting, and electroplating, enhance the visual appeal of a prototype by improving texture, gloss, and color consistency. Additionally, certain finishes can reduce friction, enhance grip, or provide electrical insulation, making them essential for functional testing in real-world applications.  

 

 

Improving Durability and Performance  

 

Many prototypes undergo surface treatments to improve wear resistance, corrosion protection, and mechanical strength. For instance, anodizing aluminum parts creates a hard and corrosion-resistant layer, while powder coating provides a durable finish for plastic and metal components. These treatments help extend the lifespan of prototypes, especially in harsh environments.  

Aligning with Production-Grade Standards  

 

Prototypes that mimic production-grade finishes provide better insights into how the final product will look and perform. This is particularly important for industries like automotive, aerospace, and medical devices, where regulatory compliance and material properties are critical. By applying appropriate surface treatments, manufacturers can refine designs and avoid costly modifications later in production.

Diamond pads are highly regarded for their remarkable versatility in the stone fabrication sector, making them an essential tool for professionals due to their wide range of applications. They are capable of handling various tasks such as grinding, honing, and polishing, delivering impeccable results on different stone materials like granite, marble, quartz, and concrete. The option to switch between coarse, medium, and finer grits allows for customization at each stage of the process, from initial surface preparation to achieving a high-gloss finish.

During the early phases of fabrication, coarse-grit diamond pads effectively remove material and smooth rough surfaces. As the work continues, fabricators can transition to finer-grit pads to enhance the finish, resulting in a polished and smooth surface. For detailed polishing, resin pads for stone provide excellent outcomes, yielding a glossy finish without harming the stone. This flexibility makes diamond pads suitable for a variety of stone surfaces, accommodating both heavy grinding and delicate polishing tasks, thus enabling fabricators to address the specific requirements of each project with accuracy.

Additionally, diamond pads are compatible with both wet and dry applications, further increasing their versatility. Wet diamond pads are perfect for cooling and minimizing dust during grinding, especially with dense materials, while dry diamond pads allow for work in tighter spaces or situations where water usage is impractical. Triangular diamond polishing pads exemplify specialized tools that assist fabrications in reaching tight corners and challenging areas, enhancing the overall versatility of the toolkit.

Unlike traditional abrasives that wear out quickly, diamond pads are built to endure extended use without losing their effectiveness. Their resilience enables them to work with a variety of stone materials while maintaining consistent performance throughout the fabrication process, minimizing the need for frequent replacement and ensuring long-term reliability.

Achieving a flawless, mirror-like finish on polished concrete is a sought-after goal for many people. Yet, streaks often appear during or after the polishing process, leaving the surface less than perfect. These streaks, which can range from faint lines to more pronounced marks, are usually the result of several contributing factors that disrupt the otherwise smooth surface.

Improper preparation of the concrete surface is a major culprit in streak formation. Concrete must be thoroughly cleaned before polishing. And residual dust, or debris trapped in the surface adequately after grinding, allowing contaminants to interfere with the polishing process and leave streaky marks behind. Using harsh chemicals or failing to remove cleaning agents entirely can also cause streaking, as residues can settle in the polished finish.

The condition of diamond grinding tools is also vital for achieving a high-quality finish. Worn or poorly maintained pads can create uneven contact with the concrete, resulting in streak-like marks. To prevent this, it is important to use high-quality hybrid transitional polishing pad, which combines the advantages of metal and resin bonds for a smoother transition between grinding and polishing, helping to eliminate surface imperfections. Furthermore, concrete resin grinding pucks yield excellent finishing results, especially during the final polishing stages, ensuring an even and streak-free surface. When used with a structured grinding process, these tools greatly minimize the risk of streaks.

Environmental factors play a significant role in the polishing process as well. Variations in humidity and temperature can impact the curing of the concrete, leading to imperfections that manifest as streaks. Polishing in hot or excessively humid conditions can worsen these issues, making it challenging to achieve a uniform finish. To improve the final shine, using 3 step flexible polishing pad can provide better control over the polishing stages, allowing for a finer finish across various conditions.

To achieve a flawless polished concrete surface, attention to detail is essential at every stage, from preparation to polishing. Utilizing the right tools, techniques, and environmental conditions can greatly reduce the likelihood of streaking and help create a beautiful, consistent finish. For those seeking the best results, investing in high-quality diamond tools such as hybrid transitional pads, resin grinding pucks, and flexible polishing pads is crucial.
