HC1, HW2 Al2O3 Type

• HC1 is a HIP (Hot Isostatic Press) processed highly pure (Al₂O₃) alumina white ceramic. This sintering process results in a highly dense and fine grain structure which improves wear resistance, tool life and toughnes. HW2 is similar HC1. The HW2 is a ceramics used in applications that need a tenacity increase of them.

Applications

• General turning and boring of gray cast iron.
• Tube scarfing finishing.
• Looping and finishing of piston shirt.

HC2, HC7, ZC4, ZC7
Al2O3-TiC Type

• These types of black ceramics consist of properly proportioned aluminum oxide and titanium carbide (Al₂O₃-TiC) sintered under pressure. The resulting products are stable over a vast range of machining conditions. The HC2 is ceramics of generic use. HC7 is a extra grade ceramic for turning and steel mills in materials of high hardness. With a gold covering, the ZC4/ZC7 grades has a finer grain structure which is best suited for hard turning versus CBN applications.

Applications

• General turning and boring of gray cast iron.
• Turning of hard materials (under HRC65).

HC6 TiC Type

• HC6 is a unique (TiC) ceramic composite material. This grade is specifically designed to machine ductile cast iron. It demonstrates superior wear resistance at high speeds. As an added benefit, this ceramic produces excellent surface finishes. HC6 toughness and thermal shock resistance surpass (Al₂O₃+TiC) ceramics. HC6 can be run with or without coolant.

Application

• Semi-finish and finish turning of ductile cast iron.
• High speed cutting of gray cast iron.
