Aluminum Alloy, Welding Wire 7.0Si - 0.52Mg (357)
|Publication Date:||1 February 2008|
This specification covers an aluminum alloy in the form of two types of welding wire.
This wire has been used typically as filler metal for gas-metal-arc and gas-tungsten-arc welding of aluminum alloy castings having similar composition and requiring, in the weld zone, response to heat treatment, properties, and corrosion resistance comparable to those of the castings, but usage is not limited to such applications.
Wire supplied to this specification is classified as follows:
Type 1 As Extruded and Sized
Type 2 As Drawn
Unless a specific type is ordered, either type may be supplied.
