1. Magnetic Strength and Holding Power
The N35UH grade of Ndfeb (neodymium-iron-boron) magnets is characterized by its high energy product of approximately 35 Mega Gauss Oersteds (MGOe). This energy product is a measure of the magnet's strength and indicates the amount of magnetic energy the magnet can store. For tile magnets, this high energy product translates to an exceptionally strong magnetic field, which provides significant holding power. This is particularly important in applications where the magnets need to securely hold tiles in place, such as in construction or decorative applications. The strength of the N35UH magnets ensures that even heavy or large tiles are firmly attached, reducing the risk of shifting or falling. This strong magnetic force also allows for the use of thinner and lighter magnets while still achieving the desired holding power, contributing to a more efficient and cost-effective solution.

2. Temperature Resistance
The "UH" in N35UH signifies that these magnets are designed to operate effectively at higher temperatures, specifically up to 180°C (356°F). This high temperature resistance is crucial in applications where the magnets are exposed to fluctuating or elevated temperatures. For example, in environments like industrial settings, outdoor installations, or areas with significant heat sources, traditional magnets might lose their magnetic properties over time. N35UH magnets maintain their magnetic strength even under such conditions. This temperature stability ensures that the magnets will continue to perform reliably and will not undergo demagnetization due to heat exposure. This characteristic is especially beneficial in tile applications that may be subject to thermal cycles or high ambient temperatures, ensuring the integrity and longevity of the tile installation.

3. Demagnetization Resistance
Demagnetization resistance refers to a magnet's ability to maintain its magnetic properties despite external influences or long-term usage. The N35UH grade provides excellent demagnetization resistance, meaning that these magnets are less likely to lose their magnetic strength over time or under stress. This is achieved through the combination of the high-grade neodymium material and precise manufacturing processes that enhance the magnet’s stability. In practical terms, this means that N35UH magnets used for tile applications will retain their holding power and effectiveness throughout their service life, even with continuous use or exposure to various environmental factors. This resistance to demagnetization is crucial for maintaining the reliability and performance of the tile magnets, ensuring that they continue to provide strong and consistent magnetic force without degradation.

4. Coating and Durability
The coating applied to N35UH magnets, often nickel (Ni) plating, plays a significant role in their durability and performance. Nickel plating provides a protective layer that shields the magnet from corrosion, physical damage, and environmental factors that could otherwise lead to deterioration. For tile magnets, this coating is essential for maintaining the magnet’s effectiveness over time. The nickel layer prevents oxidation and rusting, ensuring that the magnet’s magnetic properties remain intact even in humid or corrosive environments. Additionally, the coating helps to protect the magnet’s surface from scratches and abrasions, which could otherwise affect its performance. This enhanced durability ensures that the tile magnets can withstand various conditions and continue to perform reliably, making them a suitable choice for long-term applications where durability and performance are critical.

5. Cost and Availability
The cost of N35UH magnets is generally higher compared to lower-grade magnets due to their superior magnetic properties and temperature resistance. This increased cost reflects the advanced materials and manufacturing processes required to produce magnets with such high energy products and temperature stability. However, the investment in N35UH magnets can be justified by their enhanced performance, reliability, and longevity. In applications where strong magnetic force, temperature resistance, and demagnetization resistance are essential, the higher initial cost is offset by the benefits of reduced maintenance and longer service life. While N35UH magnets may be more expensive, their availability in the market is generally good, with many suppliers offering them in various sizes and configurations. This means that users can find suitable options for their specific needs without significant delays or difficulties.
