Q1: What is C31600 copper alloy?

A: C31600, also known as Nickel Leaded Commercial Bronze or CDA 316, is a wrought copper‑zinc‑lead‑nickel alloy belonging to the leaded red brass family. It is a free‑machining material that combines the natural corrosion resistance and machinability of C31400 with higher tensile and yield strength, achieved through the controlled addition of nickel. The alloy offers an attractive, rich bronze colour and is commonly available as rod, bar, and shaped profiles

A:Sometimes we need product specification like material standard or Grade, size, Qty, shipping port, Terms like FOB or CIF etc.

 

Q3: How long of the delivery time?

A: Usually, the shipment can be delivery within 15-30days after the order confirmed.

 

Q4: How about the payment items?

A: LC, T/T, PayPal, Western Union etc.

 

Q5: Which country have you exported to?

A: Our main market is South America, Middle East, Africa and Europe. And have built long time relationship with Pakistan, US, Norway, Germany, Korea, Russia,Taiwan customers.And got continue orders from them every month.

 

Q6: How about the MOQ?

A: Normally MOQ is 200kg, We always expect more opportunities with you. But for some special material or special size let's communicate the actual status.

 

Q7: What makes C31600 "high thermal conductivity"?

A: C31600 is often referred to as a high thermal conductivity copper alloy due to its thermal conductivity of 122 – 140 W/m·K, which significantly outperforms standard brass by approximately 20%. This property makes it highly effective in high‑temperature environments and thermal management applications, such as heat exchangers and thermal components.

 

Q8: How does C31600 compare to C31400?

A: C31600 builds upon the properties of C31400. While both alloys offer excellent corrosion resistance and machinability, C31600 provides higher tensile and yield strength due to the controlled addition of approximately 1% nickel. This makes C31600 the preferred choice for applications requiring greater mechanical strength without sacrificing corrosion resistance or machinability.
