Does Tungsten Rust
So, does tungsten rust? Pure tungsten does not undergo rust or corrosion as it develops patina on its surface. High-quality nickel-binder tungsten used for jewelry is chemically inert and undergoes corrosion in extreme conditions ie; high temperatures (above 600°C) to give a rusty look. Whereas Cobalt-binder tungsten undergoes oxidation easily due to external factors and gets corroded. Technically, rusting is a chemical process that occurs only in iron and iron alloys....
