FUJI DIE
Fuji Die KF2 Alloy ME Series


Manufacturer: Fuji Die Co., Ltd.
Model: KF2 Alloy ME Series
Feature
- The KF2 alloy, developed to combine the high toughness of high-speed steel with the wear resistance of superalloys.
- Using powder metallurgy technology, the main raw materials were changed from eutectic powder to metal powder and carbide, and the alloy was launched as the ME Series.
