Using Tungsten in Blades
The metal that a blade is manufactured with can heavily affect its attributes and cutting capabilities. As a result, making blades usually involves alloys that combine to provide multiple benefits for the finished product. In particular, tungsten is commonly used in cold saw blades due to its strong resistance to high temperatures and natural hardness.
Tungsten Cold Saw Blades
Tungsten is, in fact, a vital component of both types of cold saws. However, the application and amounts of the metal in the manufacturing process is different depending on the type of blade. This is thanks to the physical properties of tungsten which make it a versatile alloy to combine with other metals.
High-speed steel blades(HSS): HSS blades have used tungsten as an alloy since the very inception of the tool steel. By combining carbon steel with this metal and other alloys such as chromium, the forged product becomes incredibly heat resistant. As such, this heat resistance also helps to improve cutting efficiency as the blade can operate for longer periods of time before needing to cool down. This becomes especially apparent when compared to the commonly used high-carbon steel.
Tungsten-carbide Tips(TCT): As the name suggests, TCT blades use a metal-carbon compound as coating on their teeth. When applied, tungsten-carbide provides the blade teeth with extremely high abrasion resistance as well as heat resistance. This helps to sustain the blade’s sharpness for longer than HSS blades meaning more consistent clean cuts on the materials.
In essence, the importance of tungsten in blade manufacturing can not be overstated. Their natural hardness and heat resistance make them perfect for use in cold saw blades.
