Chanlon is a Grade 2 premium Scavenged Metal crafting material.
Chanlon can be obtained through the gathering crew skill Scavenging. It can be harvested from Chanlon Vehicle Debris on Balmorra (Empire) and Taris (Republic), which requires level 90 Scavenging, or from level 17-24 Scavenging missions. There is also a chance to obtain Chanlon from reverse engineering the appropriate level and type of gear.
Chanlon is used in several Armormech, Armstech, and Cybertech schematics.
