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.
