High-strength Plastalloy magnets from The Electrodyne Company are said to extend the service life of drivetrains, hydraulic lines, and filter elements by capturing metal filings, chips and other ferrous materials that would otherwise damage downstream components. Available in various configurations, including custom designed Chip Collector Magnets or embedded in Magnetic Drain Plugs, these magnets work in temperatures to 150°C. They are oil-resistant and are suitable for the extremes of automotive applications, including off-road vehicles.  

Plastalloy can be magnetized using various magnetization methods including conventional, two-poles each side, multiple-poles, or with custom magnetization patterns to suit many demanding chip-collector applications. Lead-free Plastalloy is OK in environmentally sensitive applications. Special pressure-sensitive adhesives are available to hold the magnets in place. 

Unbreakable Plastalloy can be bent, twisted, and flexed without the loss of magnetic energy, Electrodyne says. It’s available in magnet sheets, strips or die-cut shapes, with options including pressure-sensitive adhesive, polarity identification, customized formulations, and special cutting techniques. The company says its staff can provide technical assistance, including the production of specialized compounds and magnetizing fixtures to meet customers’ demands.
