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 and gas-tungsten-arc welding of aluminum alloy castings having similar composition (206.0 and A206.0) and requiring response to heat treatment, properties, and corrosion resistance in the weld zone 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.
