We bring froth an impregnable range of Cupro Nickel Tubes 90-10 For Automobile Industries. The Move To Copper-Nickel Tubing. Copper had been proved since the early days to have many good attributes. It was easy to bend and had very high corrosion resistance, but there was concern about its low corrosion-fatigue strength. When copper-nickel was introduced, it displayed corrosion resistance similar to copper, higher general strength and better fatigue strength. Good formability allows ease of flaring and bending, and although the metal cost is greater than that of steel alternatives, copper-nickel is very attractive in view of its extra life, trouble-free installation and safety/reliability characteristics.


Properties of Copper-Nickel Brake Tubing:
 

The copper-nickel alloy used for brake tubing typically contains 10% nickel, with iron and manganese additions of 1.4% and 0.8% respectively. The product conforms to ASTM B466 (American Society for Testing and Materials), which specifies dimensions, tensile strength and yield strength. Form ability and internal cleanliness conform to specifications SAE J527, ASTM A254 and SMMT C5B (Society of Motor Manufacturers and Traders). Also, the alloy meets the requirements for pressure containment, fabrication and corrosion resistance for ISO 4038 (International Standards Organization) and SAE J1047. The mechanical properties of alloy C70600 in comparison with steel and copper are shown in Alloy C70600 is normally supplied as redrawn tubing in the annealed condition. The combination of strength and good ductility give excellent formability. As copper-nickel is softer than steel, it was first feared that fretting might be a problem. Experience has shown this is not the case.


Corrosion
Resistance:
 

For many years prior to its application as a brake tubing material, alloy C70600 had been used in ships, power station condensers and hydraulic lines on tankers, and had displayed excellent resistance to saline conditions. Early tests revealed that copper-nickel has almost the same resistance to burst pressure as steel. In testing, however, when exposed to salt spray over 180 days, steel's burst strength decreases significantly. The copper alloy remains consistently resistant. For tubes covered with a moist, salty mudpack for six months, brazed steel was severely corroded resulting in perforation of the tubing wall; whereas, only superficial general corrosion was found on the copper-nickel tubing. ISO 4038 and SAE J1047 include a corrosion resistance requirement referring to ISO 3768 asking for a minimum burst pressure of 110 MPa after 96 hours in neutral salt spray. Swedish requirements include a resistance at least equal to 25µ of zinc. In all cases alloy C70600 easily exceeds the required corrosion resistance.


Copper-nickel brake tubing provides superior reliability and assures both manufacturers and vehicle owners improved durability for effective long-life functioning of the brake system.
