Copper nickel tube brief introduction

Copper nickel alloy, nickel copper Cu and Nititaniumcn, is silvery white, with metallic luster, reason of white brass.Each other between the copper and nickel can be infinite solid solution, thus forming a continuous solid solution, namely regardless of the proportion of each other, and the constant for the alpha - single-phase alloy.When melt into the copper D200 af must not be of the nickel content over 16%, the alloy color becomes relatively almost as white as silver and nickel content is higher, the color is white, but, after all, with copper, as long as the nickel content is not more than 70%, the naked eye can see the yellow brass.Besides, usually copper content of nickel in general is 25%.Cupronickel is copper and nickel alloy bills, density of 8.9 8.88 between copper and nickel
Distinguish between cupronickel and Tibetan silver, MiaoYin method is, under normal proportion, after the two relative to white, look from the table color is more close to the silver.However, under the modern technology of aluminum copper is comparable with Tibetan silver, MiaoYin color, even whiter, just high hardness, specific gravity.Tibetan silver, MiaoYin region there is no the habit of using pure copper or aluminum copper, known only some businessmen use the mould and make new rub the hand-held tool materials (especially multiplier and accessories).
Pure copper and nickel can significantly increase the strength, corrosion resistance, hardness, resistance and thermoelectricity, temperature coefficient and lower resistivity.Therefore cupronickel than other copper alloy's mechanical properties, physical properties were very good, good ductility, high hardness, colour and lustre is beautiful, corrosion resistance and deep drawing performance, is widely used in shipbuilding, oil, chemical, electrical, instrumentation, medical machinery, daily necessities, handicrafts and other fields, and are also important resistance and thermocouple alloy.Nickel cupronickel weakness is the main add elements, belong to the scarcity of strategic materials, the price is expensive.
Nickel cupronickel (also called the white brass), use: crystal oscillator components shell, crystal shell, who USES sliding piece, medical machinery, building materials, etc.
In copper alloy, copper with excellent corrosion resistance, and easy to shape, machining and welding, widely used in shipbuilding, petroleum, chemical, construction, power, precision instrument, medical equipment, instruments and other departments for corrosion of the structure.Some white brass and special electrical properties, resistance element, the thermocouple material can be made up and compensating conductor.Non-industrial use cupronickel is mainly used to make decorative handicrafts.
