This wire is cold rolled to a diamond cross section producing an ultimate tensile strength of approximately 1375-1725 MPa, mirror like surface finish of 2-4 Microns and flank hardness of RC 43-50 which is far in excess of the usual tapped materials and best suited for most of the industrial needs. HeliCoil Inserts can also be supplied in other materials such as SS-316, Inconel X-750, Titanium Alloys, Nimonic 90, Nitronic 60, Phosphorus Bronze, Beryllium Copper and with special coating and plating requirements such as Cadmium plating, Silver plating, Zinc plating, Nickel plating and dry film lubricants, Anti- Corrosion Salt spray resistant coatings.
