Cobalt Chrome SP2

Direct Metal laser Sintering Material

CobaltChrome SP2 is a Co, Cr, Mo and W based alloy in fine powder form. Its composition corresponds to type 4 CoCr dental material in EN ISO 22674:2006 standard. It also fulfills the chemical and thermal requirements of EN ISO 9693 for CoCr PFM (porcelain fused metal) of dental materials (Ni content: < 0.1 %, no Cd or Be) and requirements of EN ISO 7504, EN ISO 10993-1:2003 and 10993-5:1999 regarding the biocompatibility and cytotoxicity of the dental materials.

Applications:

This material is ideal for producing dental restorations (crowns, bridges etc.). Standard processing parameters use full melting of the entire geometry with 20 μm layer thickness.
