What do copper iron alloys belong to in the classification of substances?

Copper is a less reactive heavy metal;

Copper is a transition element.

Chemical symbol cu, English copper, atomic number.

29。Pure copper is a soft metal, the surface is reddish-orange with metallic luster when it is first cut, and the elemental color is purple-red.

The classification and color of copper you are talking about should be the classification and color of copper alloys!

In China, the commonly used copper alloys are divided into brass.

Bronze Cupronickel.

3 categories. Brass is a copper alloy with zinc as the main added element, with an attractive yellow color, collectively referred to as brass.

Cupronickel is a copper alloy with nickel as the main added element, and the copper-nickel binary alloy is called ordinary cupronickel, which has good mechanical properties and corrosion resistance, and beautiful color; The color is metallic white similar to stainless steel.

Bronze is the earliest alloy used in China, and it has a history of more than 3,000 years. Bronze originally referred to copper-tin alloy.

Later, copper alloys other than brass and cupronickel are called bronze, and are often preceded by the name of the first major added element in front of the bronze name. Its color varies according to the elements it contains, such as: phosphor bronze, beryllium bronze.

and other colors are close to or consistent with the color of pure copper, aluminum bronze is yellowish and so on.

What do steel, copper-iron alloys belong to in the classification of substances? Copper-iron alloy, he belongs to alloy products, it belongs to products such as steel, in the classification, it belongs to the metal category, not just now.

The main component of patina is basic copper carbonate, also known as salt-based copper carbonate. Structurally, it is a compound compound, (with both hydroxide and carbonate) and it can be classified as carbonate in the classification of substances.

Aeruga is in the classification of chemical substances, and it belongs to the basic salt. That's it, he's the base salt of copper carbonate.

There are three ways to classify copper alloys:

First, according to the alloy.

According to the alloy system, it can be divided into non-alloy copper and alloy copper. Non-alloy copper includes high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc., customly, people call unalloyed copper copper or pure copper, also called red copper, and other copper alloys belong to alloy copper. China and Russia divide alloy copper into brass, bronze and cupronickel, and then divide small alloy systems into large categories.

Second, by function.

According to the function, there are copper alloys for electrical and thermal conductivity (mainly unalloyed copper and microalloyed copper), copper alloys for structure (including almost all copper alloys), corrosion-resistant copper alloys (mainly tin brass, aluminum brass, all kinds of non-white copper, aluminum bronze, titanium bronze, etc.), wear-resistant copper alloys (mainly containing lead, tin, aluminum, manganese and other elements of complex brass, aluminum bronze, etc.), free-cutting copper alloys (copper-lead, copper-tellurium, copper-antimony and other alloys), elastic copper alloys (mainly antimony bronze, aluminum bronze, beryllium bronze, titanium bronze, etc.), damping copper alloys (high manganese copper alloys, etc.), art copper alloys (pure copper, simple single copper, tin bronze, aluminum bronze, white copper, etc.). Obviously, many copper alloys have polygenic functions.

3. Material formation method.

According to the material formation method, it can be divided into cast copper alloy and deformed copper alloy. In fact, many copper alloys can be used both for casting and for deformation. Normally deformed copper alloys can be used for casting, while many cast copper alloys cannot be deformed for forging, extrusion, deep drawing and drawing.

Cast copper alloys and deformed copper alloys can be subdivided into copper, brass, bronze and cupronickel for casting.

1. Red solid: copper, iron oxide.

2. Green solid: basic copper carbonate.

3. Blue solid: copper hydroxide, copper sulfate crystals.

4. Purple-black solid: potassium manganate.

5. Light yellow solid: sulfur.

6. Colorless solids: ice, dry ice, diamond.

7. Silver-white solid: silver, iron, magnesium, aluminum, mercury and other metals.

8. Black solid: iron powder, charcoal, copper oxide, manganese dioxide, ferric tetroxide, (carbon black, activated carbon).

9. Reddish-brown solid: iron hydroxide.

10. White solid: sodium chloride, sodium carbonate, sodium hydroxide, calcium hydroxide, calcium carbonate, calcium oxide, copper sulfate, phosphorus pentoxide, magnesium oxide.

Summary. Hello, copper and iron are metallic substances.

Hello, copper and iron are metallic substances.

Hello, metal is a substance with luster (i.e., strong reflection of visible light), malleability, easy to conduct electricity, heat and other properties. Substances that belong to metals are gold, silver, copper, iron, manganese, zinc, etc. At a pressure of 25 degrees Celsius, all metals are solid except for mercury (liquid).

Most of the pure metals are silver-white (gray) color, and only a few are not, such as the yellow-red color of Naixi gold and the purple-red color of copper. Most of the metals are next to the "Iron".

Hmmm, are copper and iron metallic substances.

Hello, copper and iron are both metallic substances

Okay Okay, thank you expert.

Copper alloys are alloys.

Copper alloy is made of zinc as the main added element, with a beautiful yellow color, collectively referred to as brass. The copper-zinc binary alloy is called ordinary brass chain or simple brass. Brass is an alloy made up of copper and zinc.

If it is only made of copper and zinc, it is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. Special brass is also called special brass.

More than three yuan of the attack Hui brass is called special brass or complex brass.

The copper alloy production process is made by adding other metal elements to the production and smelting it according to the chemical method that is agreed on at one beat. Copper alloy not only has the basic characteristics of pure copper, but also has other characteristics that pure copper does not have, such as not easy to rust, wear resistance, corrosion resistance and so on. Copper alloys also have very good heat resistance and are widely used in high-temperature working environments.

Applications of copper alloys

1. Power transmission: A large amount of highly conductive copper is required in force transmission, which is mainly used for power wires and cables, busbars, transformers, switches, plug-in components and connectors.

2. Motor manufacturing: In motor manufacturing, copper alloys with high conductivity and high strength are widely used.

3. Communication cables: With the development of the communication industry, the demand for optical fiber cables and copper wires is increasing.

4. Residential electrical circuits: household appliances are rapidly popularized, and residential electricity load is growing rapidly.

5. Electronics industry: from electric vacuum devices and printed circuits to microelectronics and semiconductor integrated circuits.

6. Electric vacuum devices: high-frequency and ultra-high-frequency transmitters, waveguides, magnetrons, etc., which require high-purity oxygen-free copper and diffusion-strengthened oxygen-free copper.
