Tensile strength of amalgam
Webtensile strength, maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material. Tensile strengths have dimensions of force per unit area and in the English system of measurement are commonly expressed in units of pounds per square inch, often abbreviated to psi. When stresses … WebThermal conductivity of Amalgam is 23 W/ (m·K). The heat transfer characteristics of a solid ...
