| 4043 - 5% Silicon Aluminum Welding Rods Bright Finish AWS A5.10
Class ER4043. Flows freely at 1155 °F (623 °C). Recommended for welding
3003, 3004, 5052, 6061, 6063, and casting alloys 43, 355, 356 and 214. Typical
Composition: Si 4.5-6.0%; Cu 0.30 Max.; Fe 0.80 Max.; Mn 0.05 Max.; Zn 0.10
Max.; Mg 0.05 Max.; Ti 0.20 Max.; Others 0.15 Max.; Al Balance (95%). ALLOY
4043 has a lower melting range than the base metals for which it is commonly
used and relieves contraction during weld cooling. - Used on 1xxx, 3xxx,
6xxx series alloys. 2014, 2219, 5005, 5050, 5052, 7005, 7039, N21. Al-Si,
Al-Si-Mg casting alloys and combinations of above materials. Al - Lithium
alloys. DTD372B, LM4, LM2, LM6, LM9, LM20, LM25, LM27. |

| 4047 - 11-13% Silicon Aluminum Welding Rods Bright Finish AWS A5.10
Class ER4047. Melting range 1068° - 1080°F (Eutectic point) Density: 2.66
gm/cc - Used on L159, L155, LM2, LM6, LM9, LM20. Also used for gas brazing
applications. 1xxx, 3xxx, 6xxx, series alloys. 2014, 2219, 5005, 5050, 5052,
7005, 7039. Al-Si and Al-Si-Mg casting and combinations to wrought
alloys as listed above. |

| 5356 - 5% Magnesium Welding Rods Bright Finish AWS A5.10 Class
ER5356. Flows freely at 1180 °F (637 °C) and can be used with the gas or
gas tungsten-arc welding processes. Recommended for joining 5050. 5052.
5083, 5086, 5356, 5454, and 5456. Typical Composition: Mg 4.5-5.5%; Si 0.25
Max.: Fe 0.40 Max.; Cu 0.10 Max.; Mn 0.10 Max.; Zn 0.10 Max.; Cr 0.05-0.20%;
Ti 0.06-0.20%; Others 0. 15 Max.; Al Balance (94%). 5356 is a heat treatable
alloy used for welding alloys of similar composition. 5356 is increasingly
used in preference to type 5056, since it contains Ti for grain refining.
