High Tensile Brasses

Our high tensile brasses often contain manganese and according to the alloys, addition of other elments such as nickel, iron or silicon may be possible in order to increase the mechanical properties of these copper alloys.
They offer a good friction aptitude and a good corrosion resistance.
Applications include : Automotive (valves, hydraulic fittings…) Aerospace (bushes, rings…)
