Thermoplastic Magnet Having Highly Improved Heat-Resistance

Abstract

Plastic magnets were formed with SmCo5 powder using nylon-12 (PA-12), and PBT (conventional type and low-viscosity type) binders. The magnetic properties and resistance to thermal degradation were studied. Whereas general magnetic properties were best for PA-12 magnets, such properties as the flexure strength and heat resistance were better for PBT magnets… (More)
