Cu-Ni 70/30 Socket Set Screws (UNS C71500) is a nickel – copper alloy by means of outstanding corrosion resistance and good strength in a series of media particularly sea water, sulfuric acid, alkalis and hydrofluoric acid. Meanwhile, these Cu-Ni 70/30 Anchore Screws are also being offered in different sizes and shapes to our customers. 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.
