The coefficient of thermal expansion of the specimen was then calculated to be (22.0 ± 0.1)×10 6 °C 1 for every 5°C step in the range 35°C75°C, which was in good agreement with the typical value of 23.6×10 6 °C 1 for aluminum....

Aluminum and Aluminum Alloys The dimensional change of aluminum and its alloys with a change of temperature is roughly twice that of the ferrous metals. The average CTE for commercially pure metal is 24×10–6/K (13×10–6/°F). Aluminum alloys are affected by the presence of silicon and...
The 3.2 mm thick glass typically used here would break with strains of only a few percent, even if it is tempered. The thermal expansion coefficients of Si and a polyethylene terephthalate (PET) backsheet are 2.6 and 33 ppm/°C respectively [13,14]. For a 50 °C temperature shift, this...
The in-plane TEC was close to that of aluminum, but in the direction normal to the panel was about three times that of aluminum. ☆ Presented at the 8th North American Thermal Analysis Society Conference, Atlanta, Georgia, October 16–18, 1978. 1 Present address: Department of Engineering ...
