Difference between brass and Nickel copper
Brass is an alloy composed of copper and zinc. If brass is made of copper and zinc, it is called ordinary brass. If the alloy is made up of more than two elements, it is called special brass. Such as copper alloy consisting of lead, tin, manganese, nickel, lead, iron and silicon. Brass has strong wear resistance. Special brass is also called special brass. It has high strength, high hardness and strong chemical resistance. And the mechanical properties of cutting are also outstanding. Seamless copper tubes drawn from brass are soft and wear resistant. Brass seamless tubes can be used in heat exchangers and condensers, cryogenic pipelines and seabed conveyance pipes. Manufacturing sheet metal, bar, bar, pipe, casting parts and so on. Copper containing 62% to 68%, strong plasticity, manufacturing pressure equipment.
Nickel copper is a copper-based alloy with nickel as the main additive. It is silver-white with metallic luster, so it is called white copper. Copper and nickel can be infinitely soluble with each other, and consequently form a continuous solid solution, that is, a single-phase alloy, regardless of the proportion of each other. When nickel is melted into red copper and the content exceeds 16%, the alloy color becomes as white as silver. The higher the nickel content, the whiter the color becomes. The content of nickel in white copper is generally 25%.
Advantages and disadvantages
The strength, corrosion resistance, hardness, resistance and thermoelectricity of pure copper with nickel can be significantly improved, and the temperature coefficient of resistivity can be reduced. Therefore, compared with other copper alloys, white copper has excellent mechanical and physical properties, good ductility, high hardness, beautiful color, corrosion resistance, rich deep drawing properties, and is widely used in shipbuilding, petrochemical, electrical appliances, instrumentation, medical equipment, daily necessities, handicrafts and other fields, and is also an important resistance and thermocouple. Alloy. The disadvantage of white copper is that it mainly adds elements – nickel is a scarce strategic material, and the price is more expensive.铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
