The Metal Square Piece With Precision Hole Magnet is a high-performance component designed for applications that require accuracy, durability, and reliable magnetic strength, such as electronics, aerospace, medical devices, and precision engineering. Crafted from a combination of high-quality metal (typically stainless steel, aluminum, or brass) and a powerful magnet (neodymium or samarium cobalt), this product offers the best of both worlds: the structural integrity of metal and the magnetic functionality needed for specialized tasks. The square metal casing protects the magnet from external damage, while also providing a stable base for mounting and integration into complex systems.

Measuring between 10mm to 100mm in side length and 3mm to 20mm in thickness, the metal square is precision-machined to ensure consistent dimensions and a smooth, flat surface. The precision hole—drilled using computer numerical control (CNC) technology—has a tolerance of ±0.01mm, making it suitable for applications where exact alignment is critical. The hole diameter ranges from 2mm to 15mm, depending on the size of the square, and can be customized to fit specific bolts, pins, or shafts. This level of precision ensures the magnet can be seamlessly integrated into devices like sensors, switches, or actuators, where even the smallest misalignment could affect performance.

The magnet inside is either embedded within the metal square (secured with epoxy or press-fitting) or attached to one side, depending on the application. Neodymium magnets are the most common choice, offering high magnetic flux density and strong holding force relative to their size. For high-temperature environments (such as in aerospace or automotive engines), samarium cobalt magnets are used, as they can withstand temperatures up to 350°C without losing magnetic strength. The metal casing not only protects the magnet from corrosion, impact, and electromagnetic interference but also acts as a magnetic shield, directing the magnetic field to the desired area and reducing leakage.

One of the key applications of this product is in the electronics industry, where it’s used in magnetic connectors for smartphones, laptops, and other portable devices. The precision hole allows for secure attachment to circuit boards, while the metal casing ensures reliable contact and durability. In the medical field, it’s used in diagnostic equipment (like MRI machines) and surgical tools, where precision and sterility are paramount—the metal casing can be easily sterilized, and the precision hole allows for integration into robotic surgical systems.

In aerospace and defense, the Metal Square Piece With Precision Hole Magnet is used in navigation systems, satellite components, and aircraft engines, where it must withstand extreme temperatures, vibration, and pressure. The precision machining and high-quality materials ensure it meets the strict standards of these industries, providing long-term reliability and performance.

Whether used in small electronic devices or large industrial systems, the Metal Square Piece With Precision Hole Magnet delivers the accuracy, durability, and magnetic strength needed for the most demanding applications, making it a trusted choice for engineers and manufacturers worldwide.
