CoCr Soft Milling Discs
Pre-sintered milling blanks of already proven Scheftner dental alloys.
The powder-based milling blanks are produced in special and own developed methods.
Our manufacturing process ensures excellent handling characteristics and high quality of this product group.
Starbond CoS Soft Disc
Starbond CoS Soft Disc coming soon
Binder based and powder pressed milling disc from a sintered CoCrWMo alloy.
Starbond CoS Soft Disc is based on our proven dental alloy Starbond CoS. This material has a high bonding with conventional high-fusing (low expansion) ceramics. Free of nickel, lead, beryllium and cadmium. Type 4 pursuant to DIN EN ISO 22674.
Advantages for users:
- Sinterable with all common sintering furnaces
- Simplest processing with adjusted milling strategies and tools for PMMA
- High-strength type 4 alloy with a wide range of applications
- Biocompatible
