High quality 1.0mm 4043 grade aluminium MIG welding wire. Contains 5% silicon. 4043 is one of the most widely used welding and brazing alloys and can be classified as a general-purpose filler alloy. The silicon additions result in improved fluidity (wetting action) to make the alloy the preferred choice for welders. The alloy is less sensitive to weld cracking and produces brighter, cleaner welds. Can also be used for joining cast to wrought materials. Non-heat treatable. Typical all weld metal composition - Si 5.0%, Mn <0.05%, Zn <0.1%, Fe <0.4% Al bal. Welding current DC(+)

Softer wire than 5356 and slightly harder to feed, can be used on std migs and spool on guns.
