With the continuous upgrading of medium and high-voltage power distribution equipment, high-power relays, and vacuum interrupters, copper-tungsten composite rivets have become the preferred core contact components for high-temperature and arc-resistant working scenarios. Gradually replacing traditional tungsten-iron rivets and silver-copper rivets, they effectively solve common pain points of conventional contacts, including poor conductivity, rapid arc ablation, and high long-term operational costs.

Many industrial purchasers encounter selection misunderstandings and hidden quality risks during bulk procurement. Overlooking critical material and process details often results in frequent equipment failures, unplanned downtime, and increased maintenance expenses.

Why Choose Copper-Tungsten Composite Rivets for High-Voltage Applications?

Copper-tungsten composite materials perfectly integrate the superior performance of two metals: tungsten’s excellent arc erosion resistance and anti-welding properties, plus copper’s high electrical and thermal conductivity. Under high-current switching and extreme high-voltage operating conditions, these rivets feature low power loss, stable temperature rise, and ultra-long service life.

Compared with alternative contact materials, their comprehensive advantages are highly prominent:

1. Tungsten-iron rivets: Suffer from insufficient conductivity, severe heat generation, and easy ablation under high current, making them unsuitable for high-power equipment;

2. Pure silver rivets: Come with high material costs and rapid ablation loss under high-voltage, high-current conditions, leading to uneconomical long-term operation;

3. Copper-tungsten composite rivets: Achieve an ideal balance of performance and cost, delivering stable conductivity and outstanding anti-ablation capability. They are the optimal choice for vacuum interrupters, high-power contactors, and key power distribution equipment.

To ensure stable equipment operation and reduce long-term maintenance costs, it is critical to select qualified copper-tungsten composite rivets with reliable material ratios and precise craftsmanship.
