Alnico Bar Magnet MAGMATE ABAR025X025X100 0.25×0.25×1 in 0.75 lb

Description

Product Overview

The MAGMATE Alnico Bar Magnet model ABAR025X025X100 is engineered for precision and durability in demanding industrial settings. Measuring exactly 0.25 × 0.25 × 1 inch, this rectangular bar delivers a reliable 0.75 lb holding capacity, making it an ideal choice for applications that require a compact yet powerful magnetic solution. Crafted from a high‑performance Alnico alloy—an expertly balanced mixture of aluminum, nickel, cobalt, and copper—the magnet exhibits exceptional magnetic strength while maintaining stability at temperatures up to 800 °F. The material’s rough‑cast surface can be ground to close tolerances or polished to a sleek metallic finish, providing flexibility for custom installations. Each unit is individually tested to verify magnetic pull, dimensional accuracy, and surface integrity, ensuring that every customer receives a product that meets rigorous quality standards. The magnet’s electrically conductive nature also allows for electro‑discharge machining (EDM) to create holes or custom shapes, and it can be plated for enhanced corrosion resistance when required by specific environments.

Usage

Designed with versatility in mind, this Alnico bar magnet excels in a wide range of real‑world scenarios. In electrical switchgear, its strong holding force secures contacts and busbars, reducing the risk of accidental disengagement during vibration or thermal cycling. Audio equipment manufacturers rely on the magnet’s stable field to maintain consistent speaker performance, especially in high‑fidelity systems where precision is paramount. Automotive engineers incorporate the magnet into sensor assemblies, fuel line clamps, and mounting brackets, benefiting from its ability to operate reliably under the high‑heat conditions typical of engine compartments. Additionally, the magnet is well‑suited for laboratory instrumentation, magnetic tooling, and hobbyist projects that demand a dependable magnetic component without the brittleness associated with rare‑earth alternatives. Its compact dimensions allow it to fit into tight spaces, while the 0.75 lb pull rating provides enough strength to hold medium‑sized ferrous parts securely.

FAQ

What is the maximum operating temperature for this magnet?

The Alnico material used in this magnet is rated for continuous operation up to 800 °F, making it suitable for high‑heat applications such as automotive engine bays and industrial heating equipment.

Can the magnet be drilled or modified after purchase?

Yes. Because the magnet is electrically conductive, it can be processed using electro‑discharge machining (EDM) to create precise holes or custom shapes without compromising magnetic performance.

Is this magnet compatible with standard magnetic mounting systems?

Absolutely. Its rectangular geometry and standard dimensions allow it to be used with most off‑the‑shelf magnetic brackets, plates, and mounting kits designed for bar magnets.

How does the holding capacity compare to rare‑earth magnets of similar size?

While rare‑earth magnets may offer higher pull forces per volume, the Alnico magnet provides a balanced combination of strength, temperature resistance, and durability, delivering a 0.75 lb pull that is ample for many industrial and commercial applications.

What warranty or support does MAGMATE provide?

MAGMATE offers a one‑year limited warranty covering material defects and a responsive after‑sales support team ready to assist with installation guidance, technical questions, and replacement requests.
