Our in-house heat treating department has the capability to handle high
volumes with minimal turn around. The department boasts seven
heat treating ovens and four quench tanks. To reduce
the brittleness of our aluminum castings, tempering takes place in multiple
aging ovens located through out the plant.
The majority of the output consists of an aluminum alloy known as 356-T6 which is the 356 alloy that has been tempered to the T6 designation. In this operation the aluminum is brought to just below its melting point, held at that state for up to twelve hours and then aged for up to five hours. The result is an aluminum alloy with a tensile strength of 30 ksi and a yield strength of 20 ksi.
