Alpha™ coating is an extremely hard, all-purpose, multi-layer coating that has ZrN as the top layer.  The bulk coating is much harder than its individual components. This synergy results in exceptional abrasion resistance and lubricity. 

The extreme hardness of this coating (4600 Hv) and the lubricity provided by ZrN, enable Alpha™ coating to outperform others in a wide variety of applications, especially punching, forming and cutting tools.

Alpha™ will typically last two to four times longer than TiN due to its superior hardness, abrasion resistance and lubricity.
