Condutividade t\u00e9rmica em fun\u00e7\u00e3o da temperatura para sete a\u00e7os-ferramenta \u2014 W1, H11, H13, H21, T1, T15 e M2 \u2014 em W\/m\u00b7K e Btu\/ft\u00b7h\u00b7\u00b0F, de 95 \u00b0C (200 \u00b0F) at\u00e9 815 \u00b0C (1500 \u00b0F). A condutividade determina a rapidez com que o calor se move atrav\u00e9s de uma matriz ou ferramenta: quanto maior o valor, mais facilmente a ferramenta dissipa o calor para o ambiente.<\/p>\n\n\n\n
