FAQs

Q1: What makes Chromium Zirconium Copper different from pure copper?

CuCrZr alloy contains small additions of chromium and zirconium, which significantly increase strength and softening resistance while maintaining good electrical conductivity (~80–85% IACS). Pure copper is softer and loses strength rapidly at elevated temperatures.

Q2: What is the typical conductivity of this alloy?

In the aged condition, CuCrZr achieves 80–85% IACS electrical conductivity. This makes it ideal for applications requiring both mechanical strength and efficient current transfer.

Q3: Can this material withstand continuous high-temperature operation?

Yes. The softening temperature of CuCrZr exceeds 500°C, allowing it to maintain mechanical integrity under continuous high-intensity working conditions where pure copper would soften and deform.

Q4: What product forms are available under "Platoon"?

"Platoon" refers to flat and rectangular bar/plate forms. We supply flat bars, plates, and custom-shaped profiles cut to your specified dimensions.

Q5: Do you offer custom sizes and small quantity orders?

Yes. We accept both standard and custom dimension orders. Minimum Order Quantity (MOQ) is typically 100 kg for standard sizes; smaller trial quantities may be accommodated. Please contact us with your specific requirements.
