What is the Coefficient of Linear Thermal Expansion (CLTE)?<\/h2>\n

coefficient of thermal expansion\/coefficient of linear expansion - CLTI.Any material will expand under the influence of elevated temperatures.<\/span>This can result in significant dimensional changes, part warpage, or internal stresses.<\/span><\/p>\n

The Coefficient of Linear Thermal Expansion (CLTE, often referred to as \"\u03b1\") is a material property that characterizes a material's ability to expand under the influence of elevated temperatures.<\/span>The linear coefficient 'CLTE or \u03b1' of the material is calculated as follows:<\/span><\/p>\n

\u03b1 = \u0394L \/ (L0<\/sub> * \u0394T)<\/b><\/p>\n

Among them:<\/p>\n

    \n
  • \u03b1 is the coefficient of linear thermal expansion per degree Celsius<\/li>\n
  • \u0394L is the change in specimen length due to heating or cooling<\/li>\n
  • L0<\/sub>is the original length of the specimen at room temperature<\/li>\n
  • \u0394T is the temperature change during the test, \u00b0C<\/li>\n<\/ul>\n

    Thus, \u03b1 is obtained by dividing the linear expansion per unit length by the temperature change. When labeling the average coefficient of thermal expansion, the temperature range must be specified.<\/p>\n
