Tungsten is hard and strong at room temperature, has a high recrystallization temperature, and experiences oxidation at elevated temperatures. Cold working is difficult because of its strength, and hot working is not practical because of oxidation problems.

Why is tungsten at room temperature so brittle? Since

Ductility is how easy a metal is to stretch to make it longer (like a wire). Yield strength is how easy it is to bend the metal, which involves shifting bonds. Tungsten's bonds are very strong, but it can't stretch well.

Tensile, Yield and Elongation Fisk Alloy

Elongation in wire can be measured and is reported over many different gauge lengths (2 to 60 inches) although the most common ones are 2 and 10 inches (50mm 250mm). Since elongation depends on the testing gauge length, when reporting elongation, the gauge length must also be reported (the longer the gauge length, the lower the
