Storage Secrets for Finely Polished Tungsten Carbide

Tungsten Carbide, renowned for its high surface finish and precise dimensions, demands meticulous storage. Improper storage can easily tarnish its flawless appearance, compromising product quality.

It may be commonly believed that coating metal products with oil suffices for storage. However, this approach is counterproductive for Tungsten Carbide. Unlike ordinary steel, which is cast with lower density and porosity, Tungsten Carbide is formed through powder compaction, resulting in high density and compactness. During grinding, cutting fluids containing corrosive agents are often used. If not thoroughly cleaned, these agents can, over time, cause pitting on the Tungsten Carbide surface—a common sign of corrosion.

Some attempt to apply rust inhibitors to Tungsten Carbide for protection. Yet, all rust inhibitors are volatile and, with prolonged storage, will evaporate, leaving a dull, black residue on the Tungsten Carbide’s surface, greatly diminishing its aesthetic appeal and value.

The simplest method for storing finely polished Tungsten Carbide rods is to clean the surface thoroughly and then seal them in bags. This ensures that, regardless of how much time passes, when reused, the Tungsten Carbide retains its original luster, shining brightly as ever.

Mastering the art of proper storage allows each piece of finely polished Tungsten Carbide to remain a timeless highlight in your craftsmanship.
