Product Description Product introduction Tungsten Copper contact tips are critical components in various high-performance applications due to their unique combination of excellent electrical conductivity and high thermal stability. These contact tips are primarily used in industries that require materials with both superior strength and excellent electrical properties, such as in the welding, electrical, and aerospace sectors. The unique properties of tungsten copper, a composite material, make it ideal for use in environments subjected to extreme temperatures, high electrical loads, and rapid thermal cycling.Key SpecificationsTungsten Copper contact tips are manufactured by combining tungsten (W) and copper (Cu) in specific proportions. The resulting composite material exhibits the following characteristics:Density: Tungsten Copper has a density between 15.5 and 19.3 g/cm3, which is heavier than most other contact materials but ideal for applications requiring durability and strength.Electrical Conductivity: Copper provides excellent electrical conductivity, making it highly suitable for applications where efficient transmission of electricity is required. However, the amount of copper is balanced to maintain strength and thermal resistance.Thermal Conductivity: Tungsten Copper has high thermal conductivity, allowing the contact tips to effectively dissipate heat generated during welding and other high-temperature processes.Hardness and Wear Resistance: Tungsten, being a very hard metal, imparts significant wear resistance to the contact tips. The hardness of Tungsten Copper varies depending on the tungsten content, generally ranging between 150 and 250 Vickers hardness.Melting Point: Tungsten has an extremely high melting point (around 3422°C), which is beneficial in high-temperature applications. Copper has a lower melting point (~1085°C), but the combination of both metals allows the material to withstand heat while maintaining structural integrity.Machinability: While Tungsten Copper is tough, it is still machinable to specific tolerances and shapes, which is important for producing contact tips with precise dimensions and forms. Tungsten Copper contact tips are essential components in many high-demand industries due to their unique properties of high strength, excellent electrical and thermal conductivity, and outstanding wear resistance. Whether used in welding, electrical components, aerospace applications, or automotive and defense industries, these contact tips provide critical performance advantages in environments where reliability and durability are paramount. With a balanced composition of tungsten and copper, these materials meet the rigorous demands of modern engineering, ensuring high efficiency and longevity in a wide range of applications. Typical applications Tungsten Copper contact tips are used in a variety of industries that require materials capable of withstanding extreme heat, electrical loads, and mechanical wear. Below are some of the key applications of Tungsten Copper contact tips:Welding Industry:Tungsten Copper contact tips are commonly used in resistance welding and arc welding, where they play a crucial role in transferring electrical currents between the welding machine and the materials being joined. These tips must handle high temperatures and electrical loads without degrading, making Tungsten Copper the ideal choice.Spot Welding: In spot welding, the contact tips are subjected to high electrical current and heat, making Tungsten Copper a preferred material due to its ability to handle these stresses without rapid wear.Arc Welding: Tungsten Copper tips are used in various arc welding applications, including TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding, to maintain a stable electrical connection and minimize erosion during high-temperature welding.Electrical and Electronics Industry:Due to its excellent electrical conductivity, Tungsten Copper is used in the production of electrical contacts, connectors, and switches. These components need to reliably conduct electricity without overheating or wearing down, making Tungsten Copper a go-to material.Switching Contacts: In high-power switching applications, Tungsten Copper tips provide a reliable electrical contact that can withstand the thermal and mechanical stresses involved in the operation of electrical circuits.Commutators and Slip Rings: Tungsten Copper is used in commutators and slip rings, which transfer electrical power between stationary and rotating components in motors and generators.Aerospace and Defense:The aerospace and defense industries demand materials that can endure extreme conditions, such as high altitudes, rapid changes in temperature, and high radiation exposure. Tungsten Copper is ideal for these environments because of its strength, heat resistance, and durability.Heat Shields and Heat Sinks: In aerospace applications, Tungsten Copper is used to create heat shields and heat sinks that protect sensitive equipment from excessive temperatures. The material's thermal conductivity ensures rapid heat dissipation.Automotive Industry:Tungsten Copper contact tips are used in the automotive industry for high-performance components such as ignition systems and electrical connectors.Ignition Systems: In internal combustion engines, Tungsten Copper tips are used in ignition systems that require a reliable and durable electrical connection, able to withstand the heat and vibrations produced by engine operation.Sensors and Connectors: In modern vehicles, sensors and connectors that interact with the car's electrical system benefit from the reliability of Tungsten Copper.Mining and Oil & Gas:Tungsten Copper's ability to withstand high pressures and temperatures makes it an ideal material for mining and oil & gas exploration equipment.

Typical dimensionsThe dimensions of Tungsten Copper contact tips can vary based on the specific application and the manufacturer's requirements. However, the general dimensions are designed to meet industry standards while ensuring optimal performance in high-temperature and high-electricity environments. Here are the main dimensions commonly associated with Tungsten Copper contact tips:1. DiameterStandard Diameter Range: Tungsten Copper contact tips typically have diameters ranging from 3 mm to 50 mm or more, depending on the application.Common Sizes:For welding applications, diameters of 6 mm, 8 mm, 10 mm, 12 mm, and 15 mm are common.In electrical and aerospace applications, smaller diameters such as 3 mm and 4 mm are often used.2. LengthStandard Length Range: The length of Tungsten Copper contact tips can vary from 10 mm to 100 mm, with some specialized versions going beyond this range.Common Lengths:Shorter lengths around 10 mm to 30 mm are typically used for welding and electrical connectors.Longer lengths, such as 50 mm to 100 mm, are used in applications requiring extended reach or for specific high-voltage connectors in aerospace or defense industries.3. ThicknessThe thickness of the contact tips can vary, but typically, the thickness ranges from 1 mm to 10 mm depending on the application and specific requirements.Common Thicknesses:1 mm to 5 mm for applications involving precision and minimal space.6 mm to 10 mm for heavy-duty applications requiring additional wear resistance.4. Shape and FormRound Tips: Most contact tips are round or cylindrical in shape, but they can also be customized into other shapes based on the specific application (e.g., tapered, conical, or flat).Custom Shapes: For specific applications, such as arc welding, tapered or angled tips are often preferred for better current flow and heat dissipation.Flat Contact Tips: Used in specific welding applications where a flat surface contact is required.5. ToleranceThe tolerance for Tungsten Copper contact tips is typically ±0.05 mm to ±0.1 mm for most common sizes, ensuring precision in electrical contact and thermal performance.For specialized or high-precision applications, tolerances may be tighter, such as ±0.01 mm to ±0.05 mm.6. Threaded OptionsSome Tungsten Copper contact tips come with threaded connections for easy installation and removal, particularly in welding machines or electrical connectors.Common Threads:M6, M8, and M10 threads are commonly used, but custom thread sizes can also be made to suit specific machinery requirements.7. Contact AreaThe contact area or tip face can vary depending on the use case.
