Properties of white copper: silver-white, metallic luster, melting point in 1010-1260 ℃, density 8.94g/cm³-10.49g/cm³. White copper has high strength, good ductility, moderate hardness, and can be hot and cold pressure processing.
White copper has good corrosion resistance, in seawater, organic acids and various salt solutions and other corrosive media have good corrosion resistance, alkali also has a fairly good corrosion resistance. Part of the white copper has good electrical properties, such as manganese copper with high resistance and low resistance temperature coefficient, resistance value is very stable, and copper contact with the thermal potential is not large.
Copper albite can be used in the "marine engineering field": copper albite has excellent corrosion resistance, and can be used to manufacture ship structural parts, accessories and protective devices, such as the ship's condensate tubes and heat exchangers and other parts, but also used in seawater system design, including seawater desalination plants, offshore oil and gas and other fields. Among them, iron white copper BFe10-1-1 (C70600) and BFe30-1-1 (C71500), when the mass fraction of nickel is 30% and 10%, the alloys have a wider passivation interval and the best corrosion resistance.
White copper can be used in the "electric power field": manganese copper, copper, copper, copper, copper, etc. White copper is widely used in the production of standard resistors, bridges, potentiometers, and other precision electrical measurement instruments in the working temperature of less than 100 ℃ resistance components. Kang copper and copper pair is the most excellent thermocouple working in the temperature zone of -100 ~ +300 ℃; Cao copper and nickel-chromium alloy pair composed of thermocouples, the temperature range can be from -253 ℃ (liquid hydrogen) to room temperature, the sensitivity is very high.
**Field of daily life**:
White copper can make glasses frames: China is the world's number one country in the manufacture of eyeglasses, white copper is used to make eyeglass frames because of its high strength and toughness, reasonable composition design, compound added alloying elements, grain refinement and dispersion strengthening effect is remarkable.
Copper can be used in the medical field: due to its strong antimicrobial properties, copper is often sold as a hygienic "touch material" in hospital intensive care units to minimize cross-contamination and infection.
