Nickel-copper Strip is an alloy material composed of 60% nickel, 33% copper and 6.5% iron. Nickel-copper alloy has good mechanical properties at room temperature and high temperature strength, high corrosion resistance, good wear resistance, easy processing, and non-magnetic properties. It is a good structural material for manufacturing traveling wave tubes and other electronic tubes. It can also be used as a structural material for aero-engines. Copper Nickel alloy has low electric resistance, good heat-resistant and corrosion resistant, easy to be processed and lead welded. It is used to make the key components in the thermal overload relay, low resistance thermal circuit breaker, and the electrical appliances. It is also an important material for electrical heating cable. An alloy is a material with advancing characteristics formed by fusing a metal element and one or several other elements (either metal or non-metal). The most basic substance that makes up an alloy and can exist independently is called a component, or element for short. In most cases, the components are the elements that make up the alloy. However, there are also compounds that are used as components, and the condition is that the compound neither decomposes nor undergoes any chemical reactions within the scope of the study. According to the number of components, it can be divided into binary alloys, ternary alloys or multi-component alloys. For example, simple brass is a binary alloy composed of two elements: copper and zinc; duralumin is composed of three elements: aluminum, copper, and magnesium. composed of ternary alloys. Copper and nickel can be infinitely dissolved in each other to form a continuous solid solution, that is, regardless of the ratio of each other, it is always an α-single-phase alloy. When nickel is melted into red copper D200, when the content exceeds 16%, the color of the resulting alloy becomes relatively white like silver. The higher the nickel content, the whiter the color. 70%, the naked eye will see the yellow color of copper. What's more, the content of nickel in cupronickel is generally 25%. Cupronickel is an elegant name for copper-nickel alloy, and its density is 8.9-8.88 between copper and nickel.CuNi1,CuNi2,CuNi6,CuNi8,CuNi10,CuNi14,CuNi19,CuNi23,CuNi30,CuNi44 Constantan 6J40,6J11, Manganin:6J12,6J13,6J8| Shape | Size(mm) |
