Copper Coated Bundy Tubes, Copper Brazed Double-Wall Low Carbon Steel Tube For Auto Parts
Copper Coated Bundy Tube is a type of steel tubing, typically made from low-carbon steel, coated with a layer of copper. The term "Bundy Tube" originates from the Bundy Corporation, known for manufacturing durable automotive tubing. The copper coating is applied to enhance specific properties while maintaining the structural benefits of steel. Copper Coated Bundy Tube is a versatile solution offering a balance of strength, corrosion resistance, and ease of installation, making it ideal for automotive, refrigeration, and industrial applications where these attributes are paramount.
A copper brazed double wall carbon steel tube is a specialized type of tubing used in applications requiring high strength, durability, and resistance to corrosion or pressure. It is commonly used in industries such as HVAC (heating, ventilation, and air conditioning), refrigeration, and automotive systems. The tube consists of two layers (walls) of carbon steel, providing enhanced strength and durability. The two layers of carbon steel are joined together using a copper brazing process. Copper brazing involves melting a copper alloy filler material between the two steel layers, creating a strong, leak-proof bond. This process ensures excellent thermal conductivity and corrosion resistance. The base material is carbon steel, which provides high tensile strength and durability. Carbon steel is cost-effective and widely used in industrial applications.
Key Characteristics:
Advantages:
1.High strength and durability due to double-wall construction.
2.Excellent thermal conductivity from the copper brazing layer.
3.Leak-proof and reliable performance under high pressure.
4.Cost-effective compared to fully copper or stainless steel tubes.
Manufacturing Process:
The copper coating is typically applied via electroplating or cladding, creating a thin, adherent layer. This process ensures the steel retains its structural integrity while gaining copper's beneficial surface properties.
