The Energy and Petrochemical industries are constantly battling with the effects thermal cycling has on valves and pumps in a variety of applications.  Harsh environments, high pressures, and drastic temperature cycles are challenges when trying to keep a line sealed and safe.

ALLVAR’s Alloy-16 may offer a solution in these harsh, ever-changing operating environments.

Alloy-16 is the only metal in the world that shrinks when heated, and expands when cooled.  This means it does the exact opposite of any other metal.  

A titanium alloy, Alloy-16 offers a -16 ppm/℃ Coefficient of Thermal Expansion (CTE) at 20°C and has working temperatures from cryogenic to 100℃  

Like other Titanium Alloys, it is lighter weight, non-corrosive, and has mechanical properties in line with what you would expect from a Titanium based metal.

What could this mean for Petrochemical and Energy industries?

Could Allvar be used as a spacer, seal ring, or washer in Cryogenic applications if it is expanding when everything else is contracting?  Could it solve those pesky leaks, reducing down-time, enabling a safer work environment, and saving money?

What problem will you solve with a Negative CTE metal?
