Bundy Tube
Copper-coated Bundy tube is a type of tubing that consists of a steel tube with a copper coating applied to its outer surface. The Bundy tube itself is typically made of low-carbon steel, which provides strength and durability. The copper coating is applied through a process called electroplating, where a layer of copper is deposited onto the outer surface of the steel tube.
The copper coating on Bundy tube serves several purposes:
Copper-coated Bundy tube is commonly used in automotive, refrigeration, air conditioning, and plumbing industries due to its corrosion resistance, heat transfer efficiency, and durability. It offers a cost-effective alternative to fully copper tubes while still providing the desired properties required for various applications.
