Description

Contents: 1000 g

Premium NiCr alloy for metal-to-ceramic work or composite veneering - beryllium-free

• Proven reliability in use worldwide for over 20 years

• Secure metal-ceramic bond, minimising the risk of subsequent flaking or chipping

• Low hardness of 180 (HV10) - for easy, fast finishing and polishing to a high lustre

• Simple casting time recognition - problem-free processing in all induction casting machines

• High modulus of elasticity for greater protection against deformations caused by masticatory forces

• High wearing comfort for patients thanks to the low thermal conductivity

• Biocompatible and highly corrosion-resistant thanks to a firmly-adhering passive layer - biocompatibility verified by an independent institute
