Automotive Brake Brass Tube / Pipe Specifications
Ø Brake pipe coils available in copper & 90/10 copper-nickel material manufactured to BSEN 12449 CWO24A and CW352 H respectively. Coils are available in metric & imperial sizes along with 20 or 22 gauge thickness.
Ø Seamless tubes offering better resistance to corrosion and splitting. Easy to bend, flare & install. 100% electronically & pressure tested for pin holes.
PROPERTIES OF COPPER NICKEL BRAKE TUBINGS:
The copper-nickel alloy used for brake tubing typically contains 10% nickel with iron and manganese additions of 1.7% and 0.8% respectively.
The composition conforms to BS 2871 Part 2, CN 102 designation while dimensions, tensile stress, proof pressure, formability and internal cleanliness conform to international specifications for automotive applications such as SAE J527, ASTM A254 and SMMT C5B.
The tubing satisfies the requirements of pressure containment, fabrication and corrosion resistance for ISO 4038 and SAE.
Round Seamless Brass Tubes APPLICATIONS:
Volvo, Lotus, Aston Martin, Porsche and Audi all now fit copper-nickel brake tubing as standard equipment.
It is also fitted as standard in most passenger service, freight and military vehicles, fire tenders, JCB’s and other heavy vehicles.
For the replacement market, copper-nickel brake tubing is widely available supplied in coils or straight lengths.
