The hardness of brass tubing can vary depending on alloy composition and heat treatment, but generally speaking, the hardness of commonly used brass tubing falls within the Rockwell hardness (HRB) and Vickers hardness (HV) ranges. Below are examples of several common brass tubing types and their typical hardness ranges:
Brass Alloy C23000 (Red Copper Tubing): This brass alloy typically has a Rockwell hardness (HRB) between 60 and 80 and a Vickers hardness (HV) between 130 and 160. It is a softer brass suitable for making various pipes, fittings, and decorative items.
Brass Alloy C26000 (Semi-Hard Brass Tubing): This brass alloy typically has a Rockwell hardness (HRB) between 75 and 90 and a Vickers hardness (HV) between 160 and 190. It is widely used in applications such as piping, refrigeration systems, and electrical connectors.
Brass Alloy C28000 (Hard Brass Tube): This brass alloy generally has higher hardness, with Rockwell hardness (HRB) reaching over 90 and Vickers hardness (HV) reaching over 190. It is suitable for applications that require higher strength and wear resistance, such as valves and pipes.

Packaging and shipping
GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
