Materials service provider Matexcel, Bohemia, New York, USA, has extended its range of cobalt-based metal powder products. The company now offers multi-functional Co alloys ranging from fine powders to nanostructured materials.
Cobalt-based alloys are commonly known as high wear-resistant materials and often used for dental restoration and orthopaedic implants. Typically Co alloys have an FCC crystal structure and contain alloying elements like Cr, Ni, Mo and N. Cobalt alloys typically have a higher carbon content than implantable stainless steels, which can lead to the formation of carbides distributed by the material and encourages an improvement in adhesive wear resistance. Co alloys have superior corrosion resistance compared to stainless steel, which is combined with its high wear resistance.
The Co alloy powders now available from Metaxcel include:
- MET-0023 (Co-based CoCrW); 15-53 μm, 45-105 μm
- MET-0024 (Co-based CoCrMo); 15-45 μm, 15-53 μm, 53-120 μm; 53-150 μm
- MET-0025 (Co-based CoCrMoW); 15-45 μm, 15-53 μm, 53-120 μm, 53-150 μm
- MET-0026 (Co-based GH5188); 15-45 μm, 15-53 μm, 53-120 μm, 53-150 μm
- MET-0027 (Co-based GH5605); 15-45 μm, 15-53 μm, 53-120 μm, 53-150 μm
- MET-0028 (Co-based GH5941); 15-45 μm, 15-53μm, 53-120 μm, 53-150 μm
