Types of Heating Elements A heating element converts electrical energy into heat through the process of Joule heating . Joule heating occurs when an electric current passing through the electrical element encounters resistance, resulting in the heating of the electrical element. This process is independent of the direction of current   Read More »

Nickel Chrome Alloys Their Properties and Applications The nickel-chromium system reveals that chromium is fairly soluble in nickel. It has a maximum soluble rate of 47% at eutectic temperature, which then decreases to approximately 30% at room temperature. Several commercial alloys are based on this solid solution. These alloys have   Read More »
