Prior to it's application as a
brake tubing material, the alloy C70600 was used in ships, power
station condensers and hydraulic lines on tankers, thus displaying
commendable resistance to saline conditions. According to early
tests it was evident that copper-nickel exhibits the same resistance
to burst pressure like steel.
However, in testing it was revealed that, when exposed to salt
spray over 180 days, steel's burst strength decreases significantly
and the copper alloy remains consistently resistant. The tubes
covered with moist, salty mudpacks for six months, brazed steel was
severely corroded that resulted in the perforation of the tubing
wall, infact only superficial general corrosion was found on the
copper-nickel tubing. ISO 4038 and SAE J1047 possesses a corrosion
resistance requirement that refers to ISO 3768 asking for a minimum
burst pressure of 110 MPa after 96 hours in neutral salt spray. In
all circumstances alloyC70600 exceeds easily the required corrosion
The copper-nickel brake tubing offers superior reliability thus
assuring both manufacturers and vehicle owners improvised durability
that ensures effective long life functioning of the brake system.
