Vacuum Brazing of Beryllium Bronze QBe2 Chuck for the New Energy Vehicle Industry

Beryllium Bronze (QBe2) is widely used in precision clamping and conductive components within the New Energy Vehicle (NEV) sector due to its unique combination of electrical conductivity and elasticity. However, in its raw form, QBe2 lacks sufficient hardness and structural stability for high-load applications, especially in battery assembly fixtures, sensor mounts, and connector chucks.

To overcome this, Normantherm applies vacuum brazing and heat treatment technology tailored specifically for copper-based alloys.

Why Vacuum Brazing is the Ideal Solution

• Oxidation-free processing ensures clean joint surfaces and bright appearance
• Precise shaping under controlled temperature prevents deformation
• Hardness significantly improved while retaining elasticity
• Excellent conductivity preserved, making it suitable for high-frequency electrical components

Application in New Energy Vehicle Manufacturing

The treated QBe2 chuck is used for high-precision clamping and conductive interfaces in EV motor and battery assembly lines. Its enhanced hardness allows for long-term mechanical stability, while its conductivity ensures signal accuracy and current transfer reliability.

With Normantherm’s vacuum brazing furnaces, NEV manufacturers can achieve longer component life, higher assembly accuracy, and reduced maintenance downtime.
