Tungsten Copper Foil

Tungsten Copper Foil metal composite materials produce dense hard metals with low thermal expansion, good thermal and electrical conductivity, excellent arc resistance, superior wear resistance and strength at elevated temperatures.

Copper Tungsten Alloy typical applications include high temperature furnace components, heat sinks, EDM electrodes, high-voltage discharge tubes, high voltage arc contacts, electrical contacts, vacuum contacts, electrodes for resistance welding and spark erosion, seam welding bearing inserts, leaders, balance weights, dies for castings, spreaders, microwave carriers, hermetic package bases and housings, ceramic substrate carriers, medical components, heating elements, high speed tools, flash and butt welding die inserts & facing, projection welding electrodes.

1. Mechanical Performance Characteristics. Tungsten (W) on its own is exceedingly resistant to deformation and rupturing because of its conditioning internal structure; this translates to the tungsten copper alloys possessing similar spring constant characteristics. Tungsten has an exceptionally high melting point (~3410°C) and is able to resist further deformation at high temperatures.

2. Tungsten Copper alloy has the advantage of not just high-temperature deformation resistant but also excellent wear resistance. Supporting high levels of stress and friction, tungsten copper exhibiting high hardness translates to enduring both high pressure and abrasion with abrasive materials.

Copper, like many other metals, possesses superior electrical and thermal conductivity. Therefore, tungsten copper alloy makes for efficient tools that conduct both electricity and heat with ease-reducing wasted energy and maintaining stable equipment functionality. The electrical energy losses tungsten copper alloy could help avoid rendering heat dissipation from equipment a non-issue.

3. During a change in temperature, tungsten experiences a minimal alteration in volume, therefore the foil would undergo only minute size changes that entails good fit with day to day electronic materials such as gallium arsenide, silicon wafers, and even ceramics. The result is reduced concentration of thermal stresses arising from the cap differences, hence leading to more reliable equipment structures.

4. Resistance to arc ablation. Tungsten copper foil possesses excellent arc ablation resistance due to: Its substantial withstand properties with respect to melting and expansion effusion with copper under the arc, "sweating" cooling effect copper exerts under the arc, the high boiling point and low expansion coefficient of tungsten.

5. Resistance to high corrosion and oxidization. Due to the high chemical stability of tungsten, tungsten copper alloy can effectively withstand haloes of chemicals and moisture and prevents surface rusting and aging thereby protecting internal circuits and components. This ensures greater reliability, durability, and reduced maintenance in industrial environments, infused with humidity.

6. Tungsten copper alloy inherits the superior structure and performance of tungsten, maintaining stability in high temperature environments, and not succumbing to deformation during extreme conditions of high temperatures. Therefore, it is more suitable than other alloys for works in high-temperatures conditions several other alloys may not endure.

The tungsten copper foil is primarily exercised in appliances for switching areas like medium to high voltage, medium to high current, such as contacts of protection circuit breakers and other contacts of the transmission network. Circuit breakers with voltages 500,000 V and above can use tungsten copper contacts which have 15%-20% Cu. For the purpose of grinding various precision molds and maintaining the surface speck and dimensional accuracy, tungsten copper is utilized which increases the service life of the mold and improves the product quality like plastic molds, die cast molds, stamping molds, etc. In the medical domain, surgical tools are polished up in order to use them for medical procedures increasing surface quality and biocompatibility of medical devices. Tungsten copper foil is very useful as it possesses beautiful appearance and can be used for making decorations and jewelry while showing its unique craftsmanship value along with its artistic charm.
