Overview

As a leading supplier & manufacturer in China, AEETHER supply cost-effective Coballoy 20 Products.

Coballoy 20 is the most abrasion resistant standard cobalt base alloy. It also has good corrosion resistance. Whilst it has low shock resistance, it is often the only answer for some applications such as slurry pumps or chemical resistant parts. Examples include pump sleeves, rotary seal rings, wear pads, bearing sleeves and centerless grinder work rests.

Corrosion Resistance

The typical electrode potential in sea water at room temperature is -0.2 V (SCE). Coballoy 20 shows excellent corrosion resistance in Phosphoric Acid (concentration 60%, 66°C) and in Sulphuric Acid (concentration 90%, Room Temperature). In Nitric Acid (concentration 60%, boiling) a good corrosion resistance has been observed.
