Alloy
4043(Al-Si5) is one of the oldest and most widely used welding and brazing
alloys. Chuanwang er4043 can be classified as a general purpose type filler
alloy. It is widely used in welding of 6061, 6XXX series aluminum alloy, 3XXX
series and 2XXX series aluminum and alloys.
Top Features
Spray and Flame Metallizing Wire, Welding
Filler Wire; designed for welding heat-treatable base alloys and more
specifically the 6XXX series alloys; lower melting point and more fluidity than
the 5XXX series filler alloysdue to silicon additions; low sensitivity to weld
cracking with the 6XXX series base alloys; suitable for sustained elevated
temperature service, i.e. above
