MW-4145 AlSi10Cu4 Aluminium Welding Wire
MW-4145 was originally developed as a brazing alloy due to its low melting point and high fluidity. This alloy is scarcely susceptible to cracking when used to weld alloys of series 2XXX or aluminium-copper-silicon alloys. It can be used for applications were high temperatures are required. This alloy is usually preferred to the MW-2319 alloy as it flows better in the weld pool. The weld bead has a brighter and a more “smut free” appearance with respect to other alloys. It has an ultimate tensile strength lower than alloy MW-2319. It is not recommended to use this alloy for welding aluminium alloys with a high magnesium content.
