These processing improves alloy purity and is required for Cu-Ni 70/30 Blind Rivet Screws to remove non – metallic inclusions that can form HARD spots in the material when the alloy is aged. Inclusions in Cu-Ni 70/30 Concrete Screws can result in inconsistent material properties, increased machining difficulty and processing times and ultimately part failures. Finished fabrications can be produced to a wide range of mechanical properties in Cu-Ni 70/30 Steel Shoulder Screws when proper control of the amount of hot or cold working and the selection of appropriate thermal treatments is done.
