About Cupro Nickel 70/ 30 Forged fitting
Cupro nickel 70/30, also known as copper-nickel alloy 70/30, is a socket weld fitting commonly used in various industrial applications. The alloy is composed of 70% copper and 30% nickel, resulting in a material with high corrosion resistance and strength. This type of cupro-nickel is particularly resistant to corrosion in marine environments, making it an ideal choice for saltwater applications. It has a high resistance to erosion and corrosion caused by seawater, making it a popular choice for marine engineering applications. Additionally, it has good thermal conductivity, making it ideal for high-temperature environments.
In terms of its physical properties, cupro-nickel 70/30 has a high yield strength, which makes it resistant to deformation under stress. It also has high elasticity, which can be shaped and molded easily without cracking or breaking. Additionally, it has excellent formability, which makes it ideal for use in applications where it is necessary to form complex shapes. In terms of its mechanical properties, cupro-nickel 70/30 is known for its toughness and strength, making it a reliable choice for high-stress environments. It has good impact and fatigue resistance, which means it can withstand repeated stress and strain without failing.
Cupro nickel 70/30 is a versatile and durable material for use in various industrial applications. Its excellent formability and ductility make it easy to work with. Its resistance to corrosion, high strength, and good thermal conductivity make it a reliable choice for use in harsh environments.
Our company packs cupro-nickel 70/30 socket weld fittings using high-quality materials to protect them during transportation.
