What are the key properties of cemented carbides I should be concerned with when selecting a grade for my application?
The key properties of cemented carbides that define their performance level for different applications include abrasion resistance (directly related to the hardness of the grade), fracture strength, and fracture toughness. In general, the abrasion resistance or hardness of any grade is inversely proportional to its fracture toughness. Very often grade selection involves finding the best compromise between abrasion resistance and toughness. In some instances strength and corrosion resistance can be important factors in the grade selection process.
