DETAILS

Harris® 4043 Aluminum Silicon alloy is very commonly used to weld on 6XXX base materials and other heat treatable alloys. Harris® 4043 is a soft alloy, with good crack resistance and high penetration compared to other filler metals. It can be used for certain brazing applications and to weld on high silicon casts like A356. Welding of 5XXX base materials with 4043 and other 4XXX filler metals should be avoided.

Features

  • Designed for welding heat treatable base alloys, specifically 6XXX series alloys
  • Lower melting point and more fluidity than the 5XXX series alloys
  • Low sensitivity to weld cracking with the 6XXX series base alloys
  • All-position welding
  • Often used for repair welding aluminum/silicon cast alloys such as grades 353/A356
  • Common choice for welding 6061
  • Gray color (post anodized)
