Recently, FANMETAL has launched in-depth cooperation with a well-known precision manufacturing company in Switzerland, and successfully shipped the Electrodes For Resistance Welding required by the customer through international express delivery. This cooperation focuses on our company's core product, tungsten copper inlaid electrodes, aiming to provide more competitive solutions for the global high-end manufacturing market.
Our company uses advanced powder metallurgy technology to perfectly combine high melting point tungsten (W) with high conductivity copper (Cu) to form a composite structure of "tungsten skeleton-copper filling". This unique design gives the product three core advantages:
- Extremely high temperature resistance: Under extreme working conditions above 3000℃, the copper phase quickly dissipates heat through the "sweating cooling" mechanism to ensure the stability of the electrode surface temperature and effectively extend the service life. According to third-party testing, Refractory Metal Faced Electrode still maintains more than 95% of its conductivity after 2000 consecutive weldings, far exceeding the industry average.
- High-precision processing capabilities: Using CNC machine tools for precision processing, the electrode size accuracy can reach ±0.002mm, and the surface roughness Ra≤0.2μm, meeting the stringent requirements for electrode consistency in semiconductor packaging, medical devices, and other fields.
- Extremely long life performance: By optimizing the tungsten-copper ratio (W:Cu=75:25) and microstructure, the arc erosion resistance of the electrode is improved by 40%. In the automotive wiring harness welding scenario, the single service life can reach more than 5,000 times, which is 5 times higher than that of traditional copper electrodes.
In the process of cooperation with Swiss customers, we carefully absorbed the processing and application requirements of customers and made technological innovations and process breakthroughs in product production.
- First, 0.5% of the rare earth element lanthanum (La) was introduced into the tungsten copper matrix to increase the softening temperature of the electrode from 1000℃ to 1200℃, while the conductivity was maintained above 42% IACS.
- The "stepped inlay" design was used again to increase the bonding strength between the tungsten alloy contact and the copper matrix to 350MPa, effectively solving the industry problem that traditional electrodes are easy to fall off.
- Finally, the vacuum infiltration technology was used to achieve uniform filling of the copper phase, and the porosity was controlled below 0.5%, ensuring that there was no local overheating of the electrode during high-frequency welding.
FANMETAL is a professional manufacturer of non-ferrous metals that has passed the ISO 9001 quality management system certification and has established a full-chain detection system covering raw materials to finished products:
- Raw material traceability: spectral analysis, particle size distribution test and other means are used to ensure that the purity of tungsten powder is ≥99.95% and the oxygen content of copper powder is ≤10ppm.
- Process control: In the sintering stage, an infrared temperature measurement system is introduced to monitor the temperature field distribution in the furnace in real time to ensure that the product density deviation is ≤±0.3g/cm³.
- Finished product inspection: Scanning electron microscope (SEM) and X-ray diffractometer (XRD) are used to analyze the electrode microstructure to ensure that the tungsten-copper interface bonding rate is ≥99%.
