Our Cobalt Chromium Tube is a high-performance alloy crafted for jewelry that needs to look good and last long. Made from a blend of cobalt and chromium, it boasts incredible hardness (350–400 Vickers) and resistance to scratches, dents, and tarnish. Whether it’s a wedding band or a luxury watch case, this tubing keeps its polished shine through daily wear.
What sets our tubing apart is its versatility. We customize outer diameters (0.5–50 mm), wall thicknesses (0.1–5 mm), and finishes to match your design vision. Its seamless construction ensures a flawless look, while its biocompatibility makes it safe for all skin types. Plus, at a moderate density (8.4–8.9 g/cm³), it’s comfortable to wear without sacrificing strength.
Key features include:
-
High wear resistance: Resists scratches and abrasions for lasting beauty.
-
Corrosion resistance: Stays tarnish-free in humid or chemical environments.
-
Hypoallergenic: Safe for sensitive skin, meeting biocompatibility standards.
