W70Cu30/WCu70 copper plate is a high-performance alloy material composed of 70% tungsten (W) and 30% copper (Cu), which has the characteristics of high density, high hardness, high temperature resistance and excellent conductivity.

W75Cu25/WCu75/CuW25 copper plate is an alloy material with tungsten (W) and copper (Cu) as the main components, with tungsten content of 75% and copper content of 25% (or expressed in different naming methods such as CuW25). It is a high-density, high-hardness tungsten-copper alloy. This type of material has excellent wear resistance, high temperature resistance, electrical and thermal conductivity, and is widely used in industrial scenarios such as electrodes, welding, spot welding, etc., especially suitable for occasions that require arc erosion resistance or high-strength mechanical properties.

W80Cu20 (also known as WCu80 or CuW20) is a high-performance alloy plate composed of 80% tungsten and 20% copper. It has the characteristics of high density, high temperature resistance, arc erosion resistance and high conductivity. It is widely used in electrodes, welding, aerospace and other fields.
