What are the implications of casting temperature aluminum coil elongation?
When incubated with a solid solution with the extension, tensile strength and elongation of the alloy on the rise, and to achieve the best fit to continue holding time at 1h, little change in tensile strength, and elongation decreased. This is because the solution too long holding time of the workpiece during heating recrystallization, causing coarse grains, so that the plastic lower.
Aluminum casting casting temperature optimum is not iron aluminum, and copper alloys, aluminum is generally in the 700-740, the temperature is too high is easy to burn inside the total magnesium composition, temperature is too high will also increase the total amount of intake air , made out of products susceptible to pinholes and pores.
