Due to rapid cooling solidification, alloy solidification crystallization orderly arrangement atom when too late, get solid alloy is long-range disorder structure, without grain and grain boundary amorphous alloy, called amorphous alloy, referred to as a revolution in metallurgical materials.

Granite saw blade only in the amorphous alloy powder to add between 10% and 90% of arbitrary proportion of electrolytic copper powder. Experiments prove that add 35% of the electrolytic copper powder most sharp cutting effect.
