Thermit portion, also known as thermite welding powder, is a mixture of finely powdered aluminum and metal oxide. It is used in the thermit welding process, which is a method of joining metal components by using the heat generated from a thermite reaction.
Composition: The powder consists primarily of aluminum powder and a metal oxide, typically iron oxide (Fe2O3). The exact composition may vary depending on the specific type of rails and desired results.
Reaction Temperature: The thermit reaction generates extremely high temperatures, often exceeding 2,500 degrees Celsius (4,500 degrees Fahrenheit). The reaction temperature is an important parameter that influences the melting and bonding of the metals being joined.
