1/2″ Diameter x 5/8″ Thick Alnico Deep Pot Magnet c/w M3 Threaded Hole – 4.41lbs Pull (Pack of 1)

Description

Product Overview

The Alnico Deep Pot Magnet is engineered from premium Alnico alloy, delivering a stable magnetic field that resists demagnetization even under demanding temperature fluctuations. Its compact form factor—measuring just 1/2 inch in diameter and 5/8 inch in thickness—makes it suitable for tight spaces where larger magnets cannot fit. The integrated M3 threaded hole provides a secure mounting point, allowing users to attach the magnet directly to metal plates, brackets, or custom fixtures without the need for additional hardware.

Manufactured by Magnet Expert, a recognized leader in magnetic solutions, this magnet benefits from rigorous quality control processes that include precision machining, magnetic testing, and surface finish verification. Each unit is inspected to ensure a consistent pull force of 4.41 lb, guaranteeing reliable performance across a wide range of applications. The product is packaged in a compact box measuring 3.54 x 2.28 x 1.1 inches, making storage and shipping efficient for both small workshops and large distribution centers.

Beyond its mechanical specifications, the Alnico composition offers superior corrosion resistance compared to ferrite or neodymium alternatives, extending the magnet’s service life in humid or chemically active environments. This durability is especially valuable for industrial settings where equipment may be exposed to oil, moisture, or cleaning agents. The magnet’s surface is finished to a smooth, non‑porous texture, reducing the risk of particulate accumulation and simplifying maintenance.

Designed with versatility in mind, the magnet can be employed in a variety of configurations, from fixed installations to removable fixtures. Its magnetic strength is sufficient to hold heavy components in place while still allowing for easy removal when needed, striking a balance between security and accessibility. The threaded hole also enables the addition of accessories such as washers, spacers, or custom adapters, expanding the range of possible mounting solutions.

Usage

In industrial material handling, the Alnico Deep Pot Magnet excels at securing metal pallets, trays, and containers on conveyor systems. Its pull force ensures that items remain firmly attached during rapid movement, reducing the likelihood of slippage or product loss. The threaded mounting option allows engineers to integrate the magnet directly into existing machinery, creating a seamless magnetic retention system without the need for additional clamps or fasteners.

Scientific laboratories benefit from the magnet’s precise magnetic characteristics when constructing experimental rigs, magnetic stirrers, or sample holders. The stable field and resistance to temperature-induced drift make it a reliable component for experiments that require consistent magnetic conditions over extended periods. Researchers can also use the threaded hole to attach the magnet to custom‑fabricated brackets, enabling rapid reconfiguration of experimental setups.

Custom assembly projects, such as prototype development or small‑batch manufacturing, often demand flexible fastening solutions. The Alnico Deep Pot Magnet provides a reusable, non‑permanent method for joining metal parts, simplifying the assembly process and allowing for quick adjustments. Its compact size ensures that it can be incorporated into designs where space constraints are critical, while the threaded hole offers a straightforward way to secure the magnet without compromising the overall aesthetic of the product.

FAQ

What is the temperature range for this Alnico magnet?

The Alnico Deep Pot Magnet operates reliably from -40 °C to +250 °C. Its alloy composition maintains magnetic strength across this span, making it suitable for both low‑temperature cryogenic environments and high‑heat industrial processes.

Can the magnet be used on non‑ferrous metals?

Alnico magnets attract ferromagnetic materials such as iron, steel, and certain nickel alloys. They do not adhere to non‑ferrous metals like aluminum, copper, or brass. However, the threaded hole can be used to attach the magnet to a ferromagnetic plate that is then bolted to a non‑ferrous structure, providing indirect magnetic attachment.

Is the pull force measured in a specific direction?

Pull force is measured perpendicular to the magnet’s flat face, which is the direction of maximum magnetic flux density. When mounting the magnet, ensure the pulling surface aligns with the intended load direction to achieve the rated 4.41 lb holding capacity.

How does the threaded hole affect magnetic performance?

The M3 threaded hole is machined after the magnet is fully magnetized, preserving the overall magnetic field. The small void created by the thread does not significantly diminish pull strength, allowing the magnet to retain its full 4.41 lb rating while offering a convenient mounting option.

What warranty does Magnet Expert provide for this product?

Magnet Expert offers a one‑year limited warranty covering any manufacturing defects. If the magnet fails to meet the specified pull force or exhibits material flaws within the warranty period, we will replace it at no additional cost, subject to proof of purchase.
