The difference between copper and zinc rods

       【Summary】:

The difference between copper and zinc rods is different. Copper is a pure metal with different constituent elements. The element of metal copper is Cu. Zinc alloys are alloys, and the common elements of zinc alloys are low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium.

The difference between copper and zinc rods

1. Different materials:



Copper is a pure metal, and its constituent elements are different. The element of metallic copper is Cu. Zinc alloys are alloys, and the common elements of zinc alloys are low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium.



2, the cost is different:



Copper price is 40,000 yuan / ton. Zinc alloy is 25,000 yuan / ton, and the price of copper is higher.



3. Hardness: Copper has high hardness and is more wear-resistant.



4. Plasticity;



copper:



With a wide range of copper core conductors. Used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields, it is second only to aluminum in the consumption of non-ferrous metal materials in China. Copper is a red metal, but also a green metal. The reason why it is said to be a green metal is that it has a low melting point and is easy to redissolve and re-smelt, so it is quite cheap to recycle.



Zinc rod:



Good casting performance, it can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth. Surface treatment can be carried out: electroplating, spraying, painting, grinding, grinding, etc. It does not absorb iron during dissolving and die casting, does not corrode the stamping die, and does not stick to the die. Excellent mechanical properties and wear resistance at room temperature. Low melting point, 385 melting, easy to die casting.



5. Distinguish between copper and zinc.



Physical method: Polish with fine sandpaper as the identification object. For example, the rose-red color is copper, and other colors are different kinds of copper alloys.



Chemical method: adding chemical means and acid, bubbles are soluble in alloy, no reaction is soluble in copper, zinc is soluble in hot sodium hydroxide solution, but not in copper.



Extended data:



Zinc rods: Copper can be used to make many alloys. Important alloys of copper are as follows.



1. Copper and zinc rods, named for their yellow color. Zinc rods have good mechanical properties and wear resistance, and can be used in the manufacture of precision instruments, ship parts, gun casings, etc. Really? Are gongs, cymbals, bells, trumpets, etc. real, because the percussion sounds so good? It's made of wood.



2. Zinc rods are copper, zinc and tin alloys, which are resistant to seawater erosion and can be used to manufacture ship parts and balancers.



3. Bronze: The alloy of copper and tin is called bronze, and it is named after its green color. Alloys commonly used in ancient times (such as the Chinese Bronze Age). Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties. It is used in the manufacture of precision bearings, high-pressure bearings, mechanical parts of ships that are resistant to seawater corrosion, and various plates, pipes, bars, etc.



Bronze also has an unusual property - "thermal shrinkage and cold expansion", which is used for casting statues, and can expand after cooling, with clear eyes.



4. Phosphor bronze: an alloy of copper, tin and phosphorus, which is very hard and can be used to make springs.



5. Cupronickel: Cupronickel is an alloy of copper and nickel. Its color is the same as that of silver. The silver is shiny and not easy to rust. Commonly used in the manufacture of coins, appliances, meters and decorations.



6. Eighteen-karat gold (known as 18K gold or rose gold (6/24 copper and 18/24 gold alloy). Red, high hardness, can be used as accessories and decorations. Application of zinc alloy:



Luxury zinc alloy car sign. The stand is chrome plated with zinc alloy and does not rust. Olive-shaped base, thick and firm. Use 3 meters of glue on the bottom.



Anti-theft windows with new zinc rods. The product characteristics of traditional stainless steel have begun to expose its drawbacks. Jinsheng zinc rod stained glass protective window absorbs the advantages of existing doors and windows and becomes a new product with unique functions and unique characteristics. Its safety and beauty are integrated, and it adopts a unique welding-free production line operation and a combined shuttle structure. Its birth is an epoch-making revolution in the history of protective windows.
