NPM-PARTIAL DENTURE ALLOYS

Product catalog summary

Overview: The document provides detailed information on non-precious metal alloys (NPM) used in dental applications. These alloys are noted for their excellent oral resistance and mechanical properties, suitable for various restoration indications including veneering with ceramics and acrylics, model casting, and superstructures.

NPM-Partial Denture Alloys:

MOGUCAST EH: A CoCr partial denture alloy free of nickel, beryllium, cadmium, and lead. It is biocompatible, corrosion-resistant, and offers high wearing comfort. Key properties include a proof stress of 662 MPa and a Vickers hardness of 420 HV 10.
STARBOND CO: Another CoCr alloy suitable for challenging restorations, offering excellent casting properties for 3D printed parts. It has a proof stress of 500 MPa and a Vickers hardness of 380 HV 10.
MODELSTAR S: Designed for a wide range of removable partial dentures, this alloy is also free of harmful elements and provides a proof stress of 510-600 MPa with a Vickers hardness of 355 HV 10.

NPM-Bonding Alloys:

STARBOND COS: A CoCrWMo bonding alloy for high-fusing ceramics, offering excellent metal-ceramic bonding without the need for a bonder. It has a proof stress of 650 MPa and a Vickers hardness of 280-295 HV 10.
STARBOND EASY: Similar to COS but with a slightly different composition, providing a proof stress of 610 MPa and a Vickers hardness of 285 HV 10.
STARBOND LFC: A CoCrFe alloy for low fusion ceramics, offering flexibility in ceramic selection and a proof stress of 580 MPa.
MOGUCERA C: A CoCrMo alloy with a proof stress of 508 MPa, designed for high-fusing ceramics.
MOGUCERA N: A NiCr alloy with excellent melting and casting properties, providing a proof stress of 379 MPa.
STARBOND NI: Another NiCr alloy with a lower hardness of 200 HV 10, suitable for a wide range of applications.

Technical Properties: Each alloy is characterized by specific technical properties such as proof stress, ultimate tensile strength, elongation, elastic modulus, Vickers hardness, density, melting range, preheating and casting temperatures, and laser weldability. These properties ensure the alloys meet the requirements of DIN EN ISO 22674 standards.

Conclusion: The document highlights the versatility and high performance of non-precious metal alloys in dental applications, emphasizing their biocompatibility, corrosion resistance, and suitability for various dental restoration techniques.
