Description of the case
Old Hammers:
-Casted - 2” thick – imported from China
-Problems: Long lead time, need of balancing, uneven performance from batch to batch
New Hammers:
- Hardox® 500 – 2” thick, ox fuel cut, design was optimize to have material on the areas of most wear and reduced the body width in other to keep the same weight.
- Service life is 30 - 50% better
- No need of balancing anymore (this is a thing the customer appreciated)
- Consistence performance ( now when some premature wear is detected it is an indication that the aluminum scrap is coming with excessive dirty (sand).
