What are the aluminum alloy materials used for cable trays
Basic structural members of aluminum cable tray systems can be made from 6063-T6 aluminum extrusions, a material which economically meets the requirements of the majority of installations. The 6063-T6 alloy has adequate strength and good corrosion resistance. In addition to alloying the pure aluminum by doping with elements such as copper, manganese, silicon and zinc, further strengthening is possible by the process of heat-treating. These trays are categorized based on design, application, and industry standards, each offering unique. An aluminum alloy cable tray solves these challenges by combining lightweight construction, high strength, excellent corrosion resistance, and thermal management capabilities. Some manufacturers have used this to the contractor's advantage by creating splice joints and other features which offer better performance and require less labor to install. The Aluminum Cable Ladder has a high.
