Aluminium srews
P60 and P65 aluminium screws are mainly used in areas where high corrosion resistance is required for the component (e.g. seawater-resistant aluminium screws for shipbuilding) and/or where a low weight is needed. In both cases the aluminum screws made of P60 and P65 are best suited.
Due to the special manufacturing process, strength properties are achieved which are comparable to a screw of strength class 5.6 made of steel (tensile strength 490 - 700 MPa) at only approx. 1/3 of the weight!
