The braking system of any vehicle is critical to not only the performance of the vehicle, but it is also the life saver of any person driving the vehicle. Copper Nickel Line should be used in cases where the vehicle’s underbody, will be exposed to extremely harsh environs. 1/2 copper nickel fuel line is extremely popular today. CuNi is the Molecular Formula of Copper nickel. The Elongation at Break of Copper nickel (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. In winter, rock salt and liquid sodium chloride are used to de-ice winter roads. But the dirty truth about rock salt and liquid sodium is that they destroy steel tubing lines. Brake lines made from steel contain PVF (poly vinyl fluoride), zinc, nylon plating and galfan, so as to be able to protect these from the onslaught of winter de-icing. But in spite of this, the life expectancy of such steel tubing lines, is not at all so good. Copper Nickel Brake Line is composed of 88% copper, 10% nickel and 2% iron. The Machinability of Copper nickel is 20. The Elastic Modulus of Copper nickel is 152 GPa (22000 ksi). Copper Nickel Fuel Line is used on many international car brands such as the likes of Porsche, Volvo, Aston Martin and Audi. Copper nickel has a Yield Strength of 103 MPa (15000 psi). The Density of Copper nickel is 0.323 lb/in³ (8.94 g/cm3). 3/8 copper nickel fuel line is used all over the globe today. Because of debris and sand, mix steel tubing lines do not stand much of a chance and they get destroyed. So what is the solution then?
The solution lies in the use of a completely different kind of fuel, brake and transmission line, that is made from substances against which rock salt or liquid calcium, have no bad effects. And this fuel line is made from copper nickel. Copper Nickel Line is DOT approved for hydraulic use. The Thermal Expansion Co-efficient of Copper nickel (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). 5/16 copper nickel fuel line is DOT approved for most brake systems and hydraulic brake systems. The Chemical Composition of copper nickel is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. Cupro nickel fuel pipe has a much longer lifespan than other brake lines. The Rockwell B Hardness of Copper nickel is 69. Copper nickel has a Tensile Strength of 359 MPa (52000 psi). The Shear Modulus of Copper nickel is 57.2 GPa (8300 ksi). Copper Nickel Fuel Line does not corrode or rust. Copper nickel has a Poisson’s Ratio of 0.325. The Thermal Conductivity of Copper nickel is 32.9 W/mK (0.0900 BTU in/hr.ft². °F). Copper Nickel Brake Line Tubing is an extremely popular choice with motorists today. The corrosion resistance of these brake lines made from copper nickel, are just fantastic. They do not rust out, like the way steel does. Fact is, in some cars in Europe, fuel lines made from copper nickel, have been used since the ‘70s.
Copper and copper-nickel tubes are used for vehicle brake pipes due to their good fatigue and corrosion resistance (especially against salt on the roads), where fluid loss could be disastrous. Because of their ductility, they are easy to fit; they are standard equipment for many cars, fire engines, military vehicles, JCBs and other heavy vehicles.
