AGS is the industry leader in the automotive aftermarket for steel brake, fuel, and transmission lines. Combining only the highest quality components, AGS manufactures steel lines that lead the automotive aftermarket in quality, coverage, and fill-rate. This alloy is approximately 9.2 Percent nickel, 1.4 Percent iron, 0.8 Percent manganese, and 88.6 Percent copper. Under the UNS system, this alloy is designated as UNS C70600. NiCopp therefore has the strength and structural integrity of steel lines but with the added benefit of being much more corrosion resistant. NiCopp is also easier to bend and form than steel tubing. Nickel-copper, commonly referred to as 90-10 copper, has been used on several European vehicle brake systems since the 1970's, including: Volvo, Audi, Porsche, and Aston Martin. NiCopp has been used on hydraulic/fluid transfer systems on vehicles where steel lines and tubing are commonly used. This includes brake, fuel and transmission systems. NiCopp is considered the super-premium brand in brake lines and should be considered where the underbody of the vehicle is subjected to the harshest environments, where the longest life-span for lines is required, and/or where direct OEM replacement is desired. - NiCopp Does Not Rust or Corrode - DOT Approved for Hydraulic Brake Systems - Bends 58 Percent Easier than Steel Tubing - Available in Coils of 25ft, 50ft, and 100ft - Finished Lines Available for Domestic and Import - Black Oxide Fittings 2X Corrosion Resistance. NiCopp lines and tubing meet ASTM B111 specifications.
