AI Technical Summary
Technical Problem
Existing fixing devices are vulnerable to being cut and destroyed by thieves, necessitating a need for enhanced cut-resistant materials and structures.
Method used
A locking device with an elongated metallic body reinforced by a track of hard cut-resistant material, such as tungsten carbide, dispersed in a low-melting-point self-fusing matrix, applied through welding or laser cladding, providing metallurgical joining and enhanced resistance.
Benefits of technology
The solution significantly enhances the device's resistance to cutting, ensuring durability and security against theft.

Abstract
To provide an element that is extremely difficult to cut, thereby preventing or deterring a device secured by the element from being destroyed by a thief. [Solution] The device has at least one track, which is metallurgically joined to an elongated metal body, at least one end of which can be attached to a locking unit. The material of the track has particles of a hard, cut-resistant material dispersed in a self-fusing matrix having a melting point lower than the melting point of the body, and further containing nickel, iron, and cobalt in a composition that includes chromium, silicon, and boron. The track is usually applied to the elongated body by welding, preferably laser welding or laser cladding, but plasma arc welding or brazing may be used. The low melting point prevents the elongated body from melting while allowing for metallurgical joining.
