We Cast all Aluminums, and Composites
Eck Industries has been pouring aluminum since 1948. We pour all aluminum alloys, and aluminum composites such as Duralcan. About 50% of our volume is A356 and 355, and the next most popular are 206 and 242.
Eck is known as an innovator, developing robust processes to cast advanced alloys. An example is A206, which we started in the 1970’s, and we have been developing best practices ever since. If you don't see the alloy you need, call us to make a specialty alloy for you.

Your alloy – what does your application need?
All heat treating is performed in house on castings up to 62" diameter. We offer water and air quench and we can tailor our heat treat specifications to meet your mechanical property requirements.
Heat Treat Types
F: As cast
Heat Treat Definitions
T4: Solution heat treated and naturally aged to a stable condition
T5: Cooled from an elevated temperature shaping process and then artificially aged
T6: Solution heat treated and then artificially aged
T7: Solution heat treated and overaged
Heating castings to increase ductility, which also tends to decrease strength.
Solution Heat Treat:
Heating castings to a suitably elevated temperature and holding at that temperature long enough to allow elements to enter into a solid solution and then cooling rapidly to maintain that solid solution.
Precipitation of solute atoms at room temperature (natural age) or elevated temperatures (artificial age).
Additional aging to improve dimensional stability.
