High Strength Corrosion Resistant Copper Alloy Tube for Hydraulic Brake Lines

A variety of high copper alloys has been studied to determine suitability for use in tubular form in automotive hydraulic brake lines. A 1% iron-bearing copper alloy in a light cold worked temper was found to have the strength, ductility, resistance to fatigue and to salt, and the stress corrosion characteristics required for this application.
