INTRODUCTION
Aufhauser TitaniumAlloy T-40Ti-Active provides good wetting on titanium, titanium alloys, and super alloys. It is used in a high vacuum or dry argon atmosphere. Due to its high titanium content this alloy exhibits better corrosion resistance.
APPLICATIONS
Brazing of thermal transfer products (fin-plate and tube bundle heat exchangers).
