Tungsten Rod and Tungsten Bar

The Tungsten Rod is made from high-purity tungsten metal, known for its high density (approximately 19.3 g/cm³), high melting point (around 3422 °C), and excellent hardness. It is ideal for extreme conditions and is widely used in the manufacture of high-temperature furnaces, arc electrodes, and radiation shielding materials. Shanghai Yuepeng can provide custom sizes, shapes, and compositions to meet specific demands.
