用途：
The extreme high toughness of the material makes it suitable for all types of "high and extreme high pressure and hot cutting" steel grinding operations. Main applications are:
- hot-pressed wheels for conditioning steel billets and slabs
- hot cutting operations during the casting of steel bars
- large diameter cut off wheels
- high pressure rough grinding operations
- rail grinding operations (high force)
TREIBACHER ALODUR® ZAF 25 and ZAFZ 25 are also used for blasting media and in refractories to increase the mechanical strength due to the formation of subcritical micro cracks
可供粒度：
TREIBACHER ALODURR ZAF 25 is produced in grits 4 to 46 and ZAFZ 25 in grits 4 to 36, sized in accordance with modified FEPA/ISO and ANSI sieve standards.
