Black – The surface is "as swaged" or "as drawn," retaining a coating of processing lubricants and oxides.
Cleaned – The surface is chemically cleaned to remove all lubricants and oxides.
Ground – The surface is centerless ground to remove all coating and to achieve precise diameter control.

The common processes to form tungsten rod are swaging and continuous rolling. Rotary swaging is a hammering process to forge rods. The sintered tungsten billets need to be heated to 1400 – 1600°C in a hydrogen atmosphere and then deformed to a rod shape by rotary forging on different types of swaging machines. Continuous rolling by Y type triple rolls mill is a more advanced process than swaging since it has a higher production efficiency and help tungsten rod has a better homogeneous microstructure.
