Electrical conductivity—the ability to transmit electric current with minimal loss—is the defining property of copper in electronics, power systems, and telecommunications. For components like busbars, connectors, and RF antennas, even a 5% drop in conductivity can increase energy waste and operational costs. XiaoJiao Tech's copper printing electrical conductivity technology addresses this critical need, leveraging 3D printing to produce copper parts with up to 98% IACS (International Annealed Copper Standard) conductivity—nearly matching the performance of pure, annealed copper.

Why Electrical Conductivity in Copper Printing Matters

Copper's electrical conductivity (measured in IACS) is the industry benchmark:

· Pure Copper: 100% IACS (58.0 MS/m), the standard for low-resistance applications.

· Industrial Needs: Power distribution components require ≥90% IACS; high-frequency electronics (5G, radar) demand ≥95% to minimize signal loss.

Traditional manufacturing undermines this performance:

· Machining: Creates micro-cracks and residual stress, reducing conductivity by 3-8%.

· Casting: Introduces impurities and porosity, lowering IACS by 10-15%.

· Welding/Brazing: Adds alloyed joints that act as resistive barriers, increasing energy loss in high-current systems.

XiaoJiao's 3D printed copper parts preserve conductivity through:

· Purity Control: 99.95% pure copper powder with minimal oxides, ensuring unimpeded electron flow.

· Dense Microstructure: SLM (Selective Laser Melting) achieves 99.9% density, eliminating voids that scatter electrons.

· Seamless Design: Single
