Alcotec 4145 TIG Rod

Alcotec 4145 Aluminum TIG rod

Alloy 4145 was originally developed as a brazing alloy because of its low melting
temperature and high fluidity. It provides very low susceptibility to weld cracking when
used with 2xxx series alloys or, aluminum-copper, or aluminum-copper-silicon castings. It
can be used in elevated temperature service applications.
The alloy is often preferred over 2319 when mig welding because it “wets” out better,
provides a brighter looking weld, and produces less smut. It does, however, have lower
weld tensile strengths than 2319, and it is not suited for welding high magnesium containing alloys.

Available in 10lb boxes - Rods are cut at 36" length
