Highlander 613™ 

Why Scot Forge Forges Highlander 613™ Aluminum Alloy (A96013)

During collaborative discussions with industry experts, a recurring deficiency was noted for forged aluminum products, the need for aluminum with excellent fatigue endurance, toughness and corrosion resistance characteristics. 

Scot Forge worked with these experts to perform a study evaluating suitable aluminum alloy compositions capable of meeting the strict criteria for forged components used in Naval, Aerospace and Defense applications. The results lead to the development of an alloy, aluminum 6013, that when tempered is well adapted for many forging applications.

Development of Highlander 613™

Scot Forge has devised a proprietary processing method for this aluminum 6013 and dubbed it Highlander 613™. Originally Highlander 613™ was developed as a better alternative to the traditionally forged alloy 6061 but, after reviewing and optimizing the material’s forging properties, we have also found it to present substantial benefits when compared aluminum alloys of the 7XXX and 2XXX series as an all-around versatile product.

Highlander 613™ Comparison of Material Properties

Highlander 613™ has demonstrated significantly enhanced corrosion resistance properties and is virtually immune to stress corrosion cracking. Its fracture toughness and fatigue resistance exceed many of the other 2XXX, 6XXX and 7XXX series alloys while echoing the excellent machinability of 2XXX and 7XXX series. Highlander 613™ also outperforms many of the other aerospace alloys at elevated temperatures, exceeds stress rupture properties and has superior brazeability. Additionally, Highlander 613™ can be welded by conventional means and is impervious to hot cracking during welding whereas the alloys of the 7XXX series cannot and are not.

Highlander 613™ is already being used for components in:

  • Fall pipe 
  • Subsea Remotely Operated Vehicles (ROVs)
  • Naval weapons systems
  • Commercial submarines
  • Mold-making equipment
  • National laboratory experimental programs
  • Missile and fire control systems
  • Plastic/blown film molding equipment
