Tungsten-copper (WCu) contacts, like tungsten-silver (WAg) contacts, are highly representative types of tungsten contacts. The reason their physicochemical properties, production methods, and applications are largely similar lies in the fact that both are manufactured using the refractory metal tungsten as a base. However, there is a cost difference between silver and copper, with silver generally being more expensive than copper.

Tungsten contacts are a type of electrical contact material, with their primary chemical composition including the refractory metal tungsten along with copper, silver, and other metal elements. They exhibit excellent thermal, mechanical, and electrical properties, making them widely used in the power sector. Depending on their chemical composition, tungsten contacts can be classified into tungsten-copper (WCu) contacts and Silver Tungsten (AgW) contacts.

High-Density Tungsten Alloy, also known as “high-specific-gravity tungsten alloy,” is an alloy primarily composed of tungsten (with a tungsten content of 85–99%) and small amounts of elements such as nickel (Ni), copper (Cu), cobalt (Co), molybdenum (Mo), and chromium (Cr). Its density ranges from 16.5–18.75 g/cm³, more than twice that of steel (approximately 7.85 g/cm³). Depending on the alloy composition, it can be classified into series such as W-Ni-Fe (tungsten-nickel-iron), W-Ni-Cu (tungsten-nickel-copper), W-Cu (tungsten-copper), and W-Ag (tungsten-silver).

In today’s rapidly developing automotive industry, material innovation and application have been key drivers of progress. From traditional steel to the later emergence of aluminum alloys and carbon fiber, each introduction of a new material has brought a qualitative leap in automotive performance. Beyond aluminum alloys and carbon fiber, high-density tungsten alloy is also a critical material in the automotive sector. While it may still seem unfamiliar to the general public, in the eyes of engineers, tungsten alloy is becoming a "secret weapon" for solving specific technical challenges, thanks to its exceptional properties.
