Form:

This specification covers an aluminum alloy in the form of two types of welding wire.

Application:

This wire has been used typically as filler metal for gas-metal-arc or 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.

Classification:

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.
