Our technical experts offer responsive assistance to provide input for the design and accurate quotations of your requirements.

High Temperature Break

Client – Brookhaven National Labs Application requirements: Sapphire insulator (tube) brazed to Reactor Grade (RRR) Niobium weld adapters. The Niobium and Sapphire components are specific grades for this critical application. Assembly is used as a thermal break in a beam-line application. The assembly must withstand high temperature bake-outs, and cryogenic temperatures for operation. The parts […]
