JWH 4043 x 1/8 x 1

Qualified to AWS A5.10 R4043, ABS, ISO Designation AISi5. 4043 is a 5% silicon alloy

used to weld heat treatable base alloys. It is most often used to weld the 6XXX series

of alloys. The silicon addition improves puddle fluidity, producing an appealing bead

profile. It is less crack sensitive on the 6XXX series than other welding alloys. Common

applications are automotive parts, truck trailers, bicycles. Also ideally suited for brazing

thin aluminum sheet and tubing.
