Products Description

Tungsten Contacts For Electrical Appliances, with their unique material combination and precision manufacturing process, are an ideal choice for medium and high voltage electrical applications. This product is specifically designed for high-frequency switching equipment such as horns and relays. The head uses a high-purity tungsten sheet, and the feet are fitted with iron rivets (economic type) or copper rivets (high-performance type). A stable connection is formed through a high-temperature brazing process, and the surface is covered with a nickel plating layer to prevent oxidation, achieving the core advantages of high temperature resistance, arc resistance, and low contact resistance.

Product Nature and Core Features

Head

Made of high-purity sintered tungsten sheet (W≥99.5%), possessing an extremely high melting point (3422°C) and excellent resistance to arc erosion for Car Horn Tungsten Contact Rivets.

Feet

Depending on customer requirements, iron rivets (economic/low-end solution) or copper rivets (high-performance/mid-to-high-end solution) can be selected to ensure good conductivity and assembly compatibility for Industrial Tungsten Brazed Contacts Rivets.

Connection Method

A strong metallurgical bond between tungsten and metal rivets is achieved through high-temperature vacuum brazing technology, eliminating the risk of incomplete soldering and delamination for Tungsten Contact for Circuit Breaker.

Surface Treatment

The entire surface is nickel-plated, effectively isolating air and moisture, significantly improving oxidation and corrosion resistance, and extending service life.
