The new aluminium alloy for drill pipes is one of the 6xxx-series alloys. The alloy has high strength properties at room and elevated temperatures, as well as high corrosion resistance and workability. Semi-finished extruded products from the new alloy have the following properties: UTS = 420 MPa, YTS = 380 MPa, elongation = 10% and YTS150 = 345 MPa, corrosion rate in solution (pH 11) = 0.09 g/m2 h. Based on the obtained properties, the new alloy can be used as a replacement for D16 alloy.
