Learn About Refractory Metals - The Balance
Dec 10, 2018 The strength of refractory metals at high temperatures, in combination with their hardness, makes them ideal for cutting and drilling tools. Refractory metals are also very resistant to thermal shock, meaning that repeated heating and cooling will not easily cause expansion, stress, and cracking.
