Heat treatments are also used in the manufacture of many other materials, such as glass. The most common application is metallurgical.
Heat treating is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The item system is very similar to the “channel-and-groove design” used in some toys. The item aluminum framing system has since been expanded to include a variety of t-slot nuts that have been designed for specific applications. And the T-slot nuts to fit into them comprised the first modular system developed for use in mechanical engineering in 1980 by item Industrietechnik.
