APPLICATIONS OF 6063 ALUMINIUM

Aluminium, Aluminium Bronze, Manganeese Bronze.

Aluminium alloy 6063 is used in:

  • Architectural applications
  • Extrusions
  • Window frames
  • Doors
  • Shop Fittings
  • Irrigation tubing

In balustrading the rails and posts are normally in the T6 temper and formed elbows and bends are T4.T4 temper 6063 aluminium is also finding applications in hydro formed tube for classis.

  • Weldability-Gas Excellent
  • Weldability-Arc Excellent
  • Weldability – Resistance Excellent
  • Brazability Excellent
  • Soderability Good

Welding of 6063 Aluminium

  • 6063 is suitable for all conventional welding methods.
  • Welding wire generally should be alloy 5183 or alloy 4043.
  • When maximum electrical conductivity is required use alloy 4043.
  • For Strength and conductivity use alloy 5346 and increase the size of the weld to compensate for the lower conductivity.

Supplied Forms

6063 aluminum extrusions are available from Aalco in the following form with a T6 temper:

  • Square Box Section
  • Rectangular Box Section
  • Channel
  • Equal Angle
  • Unequal Angle
  • Flat Bar
  • Tube

Aluminium alloy 6063A is a variation of 6063 aluminium with greater strength but retains the same good surface finish qualities and affinity for anodising.
