I am investigating Al6061 related research right now, and I need to input mechanical parameters like density, specific heat and so on, these parameters should be inputted different values based on different temperature condition.
However, I could only find these values on room temperature condition. Is there anyway to find the values correspond to other temperature conditions in a free way?
Thank you.
Hi Zhongkui Liu,
Some data and references can be found at

Thanks. However, it could only provide you some of them, like tensile strength. I wonder density, specific heat, conductivity, thermal expansion, elastic modulus and Poisson's ratio typically.
Dear Zhongkui,
