High-Purity Silicon Carbide Powder Supplier Providing Premium Solutions
Offering precision, durability, and reliability for your most demanding applications.
Silicon Carbide cutting tools are premium products that will generally be more costly initially than conventional carbide tools. But their longer lifespan in certain uses will often times make them an excellent long-term value.
Silicon Carbide cutting tools are tougher and last longer when cutting abrasive or heat materials than tungsten carbide. Silicon carbide cutting tools are, however, less resistant to shock, therefore making tungsten carbide harder and often better suited for interrupted or heavy cuts.
Silicon Carbide cutting tools are especially useful in machining abrasive and non-ferrous materials. They are extensively used for cutting aluminum, copper alloys, certain plastics (like PEEK), and composite materials due to their exceptional hardness and wear resistance; however, they are generally not used for cutting steel due to brittleness.
