The Trilok remelt ingot is an Alcan design that dates back to the late 1950s. Its main feature is the unique way in which each 50 lb. The ingots lock at three different points, thus the name Trilok. It is unalloyed, pure aluminum and is remelted by the customer.
Sheet ingot is cast in huge slabs, then cut to length on a large band saw.
It is alloyed to the customer's specifications and is considered a value-added product. Its end uses would include can manufacturing, aluminum building panels, lithographic plates, foil and other rolled products. Its end uses would be in products that are extruded through a die, such as door and window sash, structural members, store front curtain wall and truck panels. Since the first Kitimat Works metal was poured in 1954, the bulk of the smelter's production has been in the form of its patented Trilok remelt ingot - a pure metal product designed to be remelted and alloyed by the customer. However, the competitive global aluminum industry has changed rapidly in recent years.
