Copper Nickel 70/30 Fasteners

Copper Nickel 70/30 Fasteners

What are copper nickel 70/30 fasteners?

Compared to 90/10, these fasteners have a higher degree of tensile strength. This is because the alloy has trace inclusions of iron and manganese in addition to 70% copper and 30% nickel. Their chemical composition makes them deliver a good performance even in highly demanding applications.

Application of cuni 70/30 bolts and nut

The ability to resist biofouling and seawater corrosion enables them to be used for marine engineering purposes. They also perform well in offshore oil and gas industries. Their resistance to creep and retention of mechanical properties is why Copper Nickel 70/30 Fasteners are seen in the aerospace industry.

What does cupro nickel 70/30 fasteners tensile strength mean?

The tensile strength of a material refers to the maximum stress it can resist while it is stretched before breaking down. Copper-nickel alloys have good tensile strength ranging to about 1040 N/mm2 (size range M4 to M80)

What is the difference between cu-ni 70/30 studs and heavy hex nut?

Studs are threaded fasteners produced without a head attached to their shank. They are generally preferred in either structural or non-load-bearing applications. A heavy hex nut on the other hand is suited to load-bearing applications. Because, compared to a stud, a heavy hex nut will have a higher proof load strength.

Top 5 benefits of DIN 2.0882 hex bolts

Here are the top 5 benefits of using DIN 2.0882 hex bolts

  • Hex bolts have increased strength in elevated temperatures.
  • Superior resistance to general corrosion, pitting and crevice corrosion.
  • With higher resistance to creep even in high-temperature settings & it retains its mechanical properties in cryogenic temperatures.
  • Bolts can resist macro-fouling and they can be used in aggressive marine environments.
  • Its unique colour makes it attractive as a decorative fastener.
