product introduction

Copper foil soft connections, especially copper foil soft connections made by crimping at both ends, are indispensable flexible conductive elements in modern industry 。It is made up of multiple pieces of high-purity T2 purple copper foil, with a copper content of more than 99.95%, ensuring excellent electrical conductivity 。Its core highlight is the special pressure welding process used at both ends. Pressure welding, also known as molecular diffusion welding, is an advanced welding technology that causes diffusion movement between copper foil molecules and infiltration and fusion into one body through high temperature and high pressure heating 。This unique process eliminates stress concentration and material embrittlement problems that may occur in traditional welding, and forms a strong and extremely low-resistance contact surface, thereby ensuring the efficiency and stability of current transmission.

product advantages

Excellent electrical conductivity: High-purity T2 copper material and tight pressure welding process ensure extremely low resistivity and efficient current transmission capabilities 。
excellent flexibility: The multilayer copper foil laminated structure gives the product excellent flexibility and can adapt to the vibration, displacement, thermal expansion and contraction generated by the equipment during operation, effectively avoiding the risk of fracture of the connected hard row. 。
High reliability and stability: The molecular bond formed by the pressure welding process makes the contact surface more uniform and stable, avoiding problems such as false welding and poor contact, thereby greatly improving the service life of the product and the operating reliability of the system. 。
strong corrosion resistance: Diversified surface treatment options (tin plating, nickel plating, silver plating, etc.) enhance the product’s oxidation and corrosion resistance, allowing it to operate stably for a long time in harsh environments 。
good heat dissipation performance: Copper itself has excellent thermal conductivity and combined with a good contact surface, which helps quickly dissipate the heat generated during operation and avoids local overheating.
High degree of customization: Customized production can be carried out completely based on customers ‘specific drawings and samples to meet the needs of various non-standard products

application field
