HAYNES® Waspaloy RTW™ Filler Metal

Product Description:

HAYNES® Waspaloy RTW filler metal is used for the gas tungsten arc and gas metal arc welding of Waspaloy alloy. The deposited weld metal has excellent strength in the 1000°F-1800°F temperature range. The alloy is most commonly used for critical gas alloy turbine engine components. The RTW filler metal finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
