Key Features and Benefits of CuNi Brake Line Coil Tube:

  1. Superior Corrosion Resistance

    Copper Nickel alloys are inherently resistant to rust and corrosion, ensuring that our brake line tubes maintain their integrity even in the most challenging conditions. This resistance is particularly important in regions where roads are frequently treated with salt and other corrosive materials.

  2. Durability and Longevity

    With a tensile strength of 359 MPa (52000 psi) and excellent elongation properties (up to 40% when annealed), our Copper Nickel Brake Line Coil Tubes are designed to withstand high pressure and mechanical stress, providing a longer service life compared to traditional steel tubing.

  3. Ease of Installation

    The ductility and malleability of Copper Nickel make our brake line tubes easy to bend and flare, simplifying installation and reducing labor time. This ease of use does not compromise the strength and reliability of the tubing, ensuring a secure fit and optimal performance.

  4. DOT and SAE Compliant

    Our Copper Nickel Brake Line Coil Tubes meet all relevant industry standards, including DOT approval for hydraulic brake systems and SAE standards J1047 and ISO 4038. This ensures that our products are safe and reliable for use in various automotive applications worldwide.

  5. Versatile Applications

    In addition to brake lines, our Copper Nickel tubes are also suitable for use in fuel and transmission systems. This versatility makes them an excellent choice for high-end vehicles, including those manufactured by brands like Porsche, Volvo, Aston Martin, and Audi.
