The manufacturing process of cemented carbide rods mainly includes the following steps

December 01,2023

Preparation of raw materials:

The raw materials for preparing cemented carbide rods  include refractory metal compounds (such as tungsten, molybdenum, chromium, titanium, etc.) and bonding metals (such as cobalt or nickel). These raw materials need to be prepared by powder metallurgy.

Press molding:

Put the prepared raw material powder into the mold and apply pressure to form it.


Put the pressed body into a sintering furnace and sinter it at a certain temperature to diffuse and rearrange the metal atoms in the body to form a cemented carbide rod with the required shape and properties.

Heat treatment:

In order to further improve the performance of cemented carbide rods, heat treatment is required, including quenching, tempering and other steps.


After heat treatment, carbide rods require further processing, such as turning, milling, etc., to obtain the required dimensional and shape accuracy.

Quality inspection:

Carry out quality inspection on the processed carbide rods , including appearance inspection, dimensional inspection, performance test, etc., to ensure that the product meets the requirements.

It should be noted that the above are just the general steps of the cemented carbide rod manufacturing process, and the specific manufacturing process may vary due to different manufacturers and different product requirements.
