Abstract
The use of aluminum and special alloys of aluminum in the construction of large installations as is the case of vulcanization equipment, cause a substantial reduction in their weight, while increasing the useful capacity used in the joint process. Metallic structure of vulcanization equipment is made of aluminum alloy 3L59, and after a period of use it was found a deterioration of the quality of joints caused by the modification of the properties of the metallic structure from 3L59. The modification of the properties of the metallic structure is determined by the presence of heat in the vulcanization process and in this regard it has been made an analyze of modifications of metallographic structure and hardness which occur in aluminum alloy 3L59.
