Aesteiron Steels LLP, is amongst the leading Copper Nickel Fasteners Manufacturers. It is available in different grades and specifications. It being manufactured from high grade of qualitative material for durability, reliability, sturdiness & for better and longevity performance
Cupro Nickel Fasteners is made up of an alloy of copper that consist nickel and other strengthening components, such as iron and manganese.
Copper Nickel Bolts is a threaded fastener which has an external male thread requiring a matching pre-formed female thread such as a nut. It is very closely related to screws. Its copper content typically varies from 60 - 90 %. It is generally chosen for sea water parts and service equipment contains 10 – 30 % nickel.
Copper Nickel Screws is an externally threaded fastener which is capable of being inserted into holes in assembled parts. It is used to fasten materials by the engagement of the screw thread with a similar female thread in the matching part. It is commonly used in seawater due to its complete resistance to barnacles. Due to its resistance of various sea organisms, this alloy makes seawater desalination, water systems, fire-fighting systems, and similar applications very reliable.
Copper Nickel Alloy Fasteners are used to create non-permanent joints; i.e., joints that can be dismantled or removed without damaging the joining elements.It has an essential addition of iron and manganese, which are necessary to maintain good corrosion resistance in the harsh environments. It is very thermally stable aside from being very corrosion resistant to sea water.
Cuni Bolts and Nuts is fasteners whereas cuni bolt consists of a head and a cylindrical body with screw threads along a portion of its length. Cuni nut is the female member of the pair which has internal threads to match bolt.
