CNPC Powder establishes silver powder production line for EV manufacturer
February 13, 2025
CNPC Powder, headquartered in Vancouver, Canada, with metal powder production based in Fengyang, Anhui, China, reports it has officially launched a proprietary intelligent production line (Ag-AMP) for the manufacturing of ultra-high quality silver powder, designed and customised for a leading manufacturer of new energy vehicles.
This Ag-AMP has an annual capacity of 30 metric tons, with products tailored for Additive Manufacturing and other advanced applications. Ag-AMP is also scalable to accommodate growth in the EV market and other advanced industries.
Silver, with its unmatched electrical conductivity (6.3×10⁷ S/m), makes it ideal for high-frequency and precision electronic components. Its low-temperature processability prevents thermal damage to substrates, giving it unique advantages in Cold Spray and Binder Jetting Additive Manufacturing technologies.
In Additive Manufacturing, silver powder demonstrates potential in the electronics, new energy and medical sectors, enabling applications such as conductive circuits, 5G/6G radio frequency devices, biosensors and cold spray coatings. This technology is said to excel in creating complex porous or lattice structures to improve thermal management and minimise material waste, a key advantage for cost-sensitive precious metal applications.
CNPC Powder’s innovative production line delivers premium silver powder with:
- Ultra-high purity (Ag >99.99%)
- Superior sphericity (>92%)
- High apparent and tap density
- Minimal satellite particles and hollow powder
- Customisable particle sizes: 0-25 μm, 15-45 μm, 45-150 μm
The fully automated Ag-AMP line integrates quality control systems. CNPC Powder notes the following key technological advantages as driving industrial improvements:
- Digital management: MES system enables full-process traceability from raw materials to finished products
- Purity assurance: 100,000-class cleanroom guarantees impurity-free production
- Precision grading: Airflow classification technology achieves particle size distribution CV <15%
- Customisation: Supports tailored specifications across 0-150 μm particle ranges
Ag-AMP incorporates a number of eco-friendly innovations, such as a closed-loop water cooling system that has a 30% reduction in energy consumption. CNPC Powder’s full life-cycle silver management system achieves a material recovery rate of over 99%, which significantly reduces customers’ precious metal costs, it was stated.
CNPC Powder offers a comprehensive portfolio spanning materials based on aluminium, titanium, iron, nickel, copper and precious metals. These products meet a variety of advanced manufacturing needs in Additive Manufacturing, MIM and cutting-edge technologies. Looking ahead, CNPC Powder intends to sustainably drive innovation in high-end materials, offering customised solutions to accelerate technological progress and industrial transformation around the world.
