CTE evaluation of thin Al sheet by TMA tensile loading method

TA-1031: CTE evaluation of thin Al sheet by TMA tensile loading method



Thermomechanical analysis (TMA) is a method in thermal analysis that measures the change in length caused by expansion or shrinkage of a material as a function of temperature or time. In TMA, the measurement mode or attachment depends on the sample shape and measurement objective. The tensile loading attachment is suitable for materials such as fiber, sheet and films for the measurement of expansion and shrinkage. Here, the sample is clamped or fixed on both ends and the load is applied in the tensile direction. In this application, we apply the tensile loading method on the measurement of expansion of a thin aluminum sheet.

TG-DTA is a hyphenated technology generally referred to as simultaneous thermal analysis (STA).



DSC is a thermal analysis technique that quantifies the amount of energy in a reaction.

DSC with industry-first self-diagnostic feature and industry's highest temperature range

Quantifies the energy changes in reactions such as melting, transition, crystallization and glass transition temperature.

DSC8271 is a high-temperature type DSC with a maximum temperature of 1,500°C.

TMA is the measurement of a change in dimension or mechanical property of the sample while it is subjected to a controlled temperature program.


The compact humidity generator (HUM-1) is connected to the TG-DTA for measurements under constant relative humidity water vapor atmosphere.


TMA/HUM measures change in dimension or mechanical property of a sample while subjected to a temperature regime under water vapor atmosphere with a constant relative humidity.

In TG-FTIR, gases evolved by volatilization or thermal decomposition are qualitatively analyzed, which allows you to track changes in the generated amount along with the temperature change.
