Notes:

1.        Recommendations are for plate of "0" temper.

2.        Ductility of weldments of these base metals is not appreciably affected by filler metal.
elongation of these base metals is generally lower than that of other alloys listed.

3.        For welded joints in 6061 and 6063 requiring maximum electrical conductivity use 4043
filler metal. However, if both strength and conductivity are required, use 5356 filler
metal and increase the weld reinforcement to compensate for the lower conductivity of
5356.
