    58MS/m=100%IACS;  1%IACS=0.58MS/m;  1MS/m=1.7241%IACS

3. ¡°-¡± represents no data available

4. 1W/(m¡¤K) =1W/(m¡¤¡æ)

5. Data with light blue color is only for reference

6 *27 represents the temperature of 20¡æ. The shear strength is 27MPa if the elongation rate is 0.1mm/min. In most cases, the shear strength decreases with temperature.
