Description

Titanium UNS R56260 is an Alpha-Beta Alloy and it’s generally regarded as the workhorse alloy of the titanium industry. The alloy is fully heat-treatable in section sizes up to one inch and is used up to approximately 400°C (750°F). Since it is one of the most commonly used alloys (over 70% of all alloy grades melted are a sub-grade of Ti-6-4,) its uses span many aerospace engine and airframe components. Titanium UNS R56260 is also used in lots of non-aerospace applications such as marine, offshore and power generation industries. This Alpha-Beta Alloy combines good corrosion resistance and strength with weldability and fabricability. The alloy is generally available in bar form and it’s typically used in deep sour well applications. This alloy can be hot or cold formed.
