How to find the isotropic secant coefficient of thermal expansion for this material .

1) AL 7475 Density: 2.81g/cc ,Young’s Modulus: 70.3GPa , Poisson’s Ratio: 0.33 ,Thermal Conductivity: 163 W/m-K ,Specific Heat Capacity: 0.88 J/g-°C

2) Nickel Aluminium Bronze Alloy Density: 7.53g/cc Young’s Modulus: 110GPa Poisson’s Ratio: 0.32 Thermal Conductivity: 41.9 W/mK Specific Heat Capacity:419.0 J/kg

3)  Graphite Cast Iron Density: 7.91g/cc Young’s Modulus: 99GPa Poisson’s Ratio: 0.21 Thermal Conductivity: 46 W/mK Specific Heat: 490 J/kg

4) Sand Cast Magnesium Alloy Density: 1.81g/cc Young’s Modulus: 45GPa Poisson’s Ratio: 0.35 Thermal Conductivity: 62 W/m.K Composition: Aluminium 10.7% Magnesium 90% Zinc 0.3%

You have two posts asking the same question. Please post in only one category. Here is a link to the duplicate post: /forum/discussion/35274/steady-state-thermal-analysis
From your comment in this post, /forum/discussion/8366/getting-results-as-zero#latest I opened the PDF file and found this table with the sentence in bold below...
Online means using Google to search for CTE material properties. Do that and you will find this and many others.
