About Cupro Nickel 70/30 Fasteners:
Copper Nickel 70/30 Fasteners are finished with a chemical composition like chromium, iron, copper, manganese, silicon, carbon, and titanium. These fasteners are constructed with various specifications such as grade, acceptance, form, dimension, application areas, surface, finishing, shape, size, thickness, width, form, and length. The dispensation of these fasteners is done under highly innovative machines with the management of technical experts. This lessens any possibility of low-quality fabrication. Consumers favor these fasteners for engineering fastening usages.
These fasteners restore those heavy and bulky fasteners, even presenting a similar service. Moreover, these are the most reasonable option than evaluating other standard-grade fasteners.
Features of Cupro Nickel 70/30 Fasteners:
These fasteners are also planned with the help of physical and mechanical features like density, modulus of elasticity, tensile power, yield power, elongation, thermal conductivity, electrical conductivity, melting point, impact potency, and last tensile strength.
Table of Content
Advantages of Cupro Nickel 70/30 Fasteners:
These fasteners show exceptional resistance to alkaline solutions and neutrals. These fasteners have greater thermal and electrical features. Also, these fasteners are excellent conductors of heat. These fasteners are poor conductors of electricity. They present a significantly lower electrical conductivity as compared to other fasteners. These are recognized to deal with galvanic erosion if other metals come in contact with this nickel alloy in an acidic situation.
The mechanical features of these fasteners make them appropriate for many industrial operations. They comprise nickel alloy and several additional contents in it. Also, these fasteners have hardiness and strength as evaluated to other materials. These fasteners exhibit extraordinary resistance even at high-temperature applications.
Application of Cupro Nickel 70/30 Fasteners:
These fasteners are applicable in many industries such as chemical processing, food processing, gas, petrochemical, power generation, paper, pulp, refining plant heat exchangers, condensers, specialty chemical plants, pharmaceutical tools, chemical tools, etc.
Kalp Industries is a significant manufacturer, seller, and stockiest of the Cupro Nickel 70/30 Fasteners. We also produce the modified form of the complete product as per the customer’s dimensions and orders. We are offering these fasteners at very reasonable rates.
