Balzers, Inc. has added a second member to its G6 family of AlCrN-based coatings, which is offered as an alternative to titanium-based coatings. Balinit Helica is suitable for common steel and cast iron qualities, for internal and external cooling, for dry machining or with minimum quantity lubrication. Potentail product benefits include reduced wear and favorable hot hardness and chip evacuation.
