tungsten nickel copper alloyProduct Introduction
Flight management and Inertial Navigation Systems (INS) operate in extreme kinetic environments where both mechanical vibration and rogue magnetic fields can critically degrade navigational accuracy. The tungsten nickel copper alloy directly resolves this dual challenge. Produced via an advanced near-net shape powder metallurgy (PM) process, this specialized component utilizes a W-Ni-Cu (Tungsten-Nickel-Copper) alloy matrix. This exact formulation allows the heavy mass required for structural stabilization to be integrated directly into avionics bays without introducing any magnetic interference, ensuring absolute precision for intricate flight sensors and directional arrays.
