What material is the alloy?

Question 1: What material does the alloy belong to? Generally speaking, anything that is not pure metal but contains other metals or nonmetals in one metal is an alloy. Such as pig iron,

Ordinary low carbon steel is an iron-carbon alloy.

The alloy we usually talk about refers to a kind of material which is made by adding one or more other elements in a certain proportion through metallurgy. This material has special physical and mechanical properties that a single metal does not have.

There are too many alloy materials. Stainless steels commonly used in China are iron-chromium alloys with chromium content above 13% and aluminum-magnesium alloys for aircraft. ...

Question 2: What is the material of Lumite alloy? This material is not widely used in Lewis sulfuric acid pump, sulfur pump, phosphoric acid pump and sulfuric acid valve in the United States, and it is difficult to buy.

Whether these two materials can be replaced depends on the customer.

Question 3: Is there a difference between alloy and metal? Metal materials include two categories: pure metals and alloys. Pure metals such as pure iron, pure copper, pure aluminum, etc. Alloys, such as steel, brass, bronze and aluminum alloy, are all metal materials.

So the difference between alloy and metal material is the difference between son and Lao Tzu, the difference between potato and vegetable, and the difference between rice and grain.

Question 4: What is the material of K alloy? K gold refers to the alloy in which gold and other metals are mixed together. Because its English is Karat Gold, it is called k gold for short. Kai is the unit of measurement of K gold, which divides pure gold into 24 parts.

Question 5: What is an alloy material? It is a substance with metallic characteristics synthesized by two or more metals and nonmetals through a certain method. Generally, it is melted into a uniform liquid and solidified. According to the number of constituent elements, it can be divided into binary alloy, ternary alloy and multicomponent alloy. According to the different structures, the main types of alloys are:

(1) mixed alloy (* * * molten mixture) is an alloy formed by crystallization of alloy components when liquid alloy solidifies, such as solder and bismuth cadmium alloy.

(2) solid molten alloy, in which solid solution is formed when liquid alloy solidifies, such as gold and silver alloy;

(3) Intermetallic alloys, that is, alloys in which components form compounds with each other, such as brass (β-brass, γ-brass and ε-brass) composed of copper and zinc.

Many properties of alloys are superior to pure metals, so alloys are often used as application materials (see ferroalloy and stainless steel).

Commonality of alloys

All types of alloys have the following commonalities:

(1) The melting point of most alloys is lower than that of any constituent metal;

(2) Hardness is generally greater than that of any metal in its composition; (Special case: Sodium-potassium alloy is a liquid, which is used as a thermal conductor in atomic reactors)

(3) The electrical conductivity and thermal conductivity of the alloy are lower than those of any component metal. Using this characteristic of alloy, materials with high resistance and high thermal resistance can be manufactured. It can also make materials with special properties, such as adding 15% chromium and 9% nickel to iron to obtain a corrosion-resistant stainless steel, which is suitable for chemical industry.

(4) Some have strong corrosion resistance (such as stainless steel).

2. Ordinary alloy

Ductile iron, manganese steel, stainless steel, copper, bronze, white copper, solder, hard aluminum, 18K gold, 18K platinum.

Question zh62 stands for what alloy material is used to cast brass?

Z stands for casting, H stands for brass, and 62 stands for copper with a mass fraction of 62%.

Brass is an alloy of copper and zinc. Brass composed of copper and zinc is called ordinary brass. Brass is usually used to make connecting pipes for valves, water pipes, air conditioners and radiators.

The code name is represented by "H+ number", H stands for brass, and the number represents the mass fraction of copper.

For example, H62 stands for brass with copper content of 62% and zinc content of 38%, and the word "Z" is added before the code name of cast brass, such as ZH62.

Question 7: What is the material of12clmovg? Is it alloy steel or alloy? 12Cr 1MoVG is the material of alloy pipe. It is mainly used for manufacturing steel structures in boilers. When the service temperature reaches 580℃, the steel plate is required to have high high-temperature durable strength, and the steel plate is delivered in normalized and tempered state. 12Cr 1MoV alloy pipe is based on high-quality carbon structural steel, and one or several alloying elements are appropriately added to improve the mechanical properties, toughness and hardenability of the steel. Products made of this steel usually need heat treatment (normalizing or tempering); Parts made of it usually need to be tempered or surface chemically treated (carburizing, nitriding, etc.) before use. ), surface quenching or high frequency quenching. Therefore, according to the difference of chemical composition (mainly carbon content), heat treatment process and application, this kind of steel can be roughly divided into carburized steel, quenched and tempered steel and nitrided steel.

Question 8: What material does alloy steel belong to? Alloy steel means that in addition to iron and carbon, other elements are added to steel, which is called alloy steel.

An iron-carbon alloy formed by adding one or more alloying elements to ordinary carbon steel. According to different added elements and proper processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance and non-magnetism can be obtained.

The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, aluminum, copper, boron and rare earth. Among them, vanadium, titanium, niobium, zirconium, etc. It is a strong carbide forming element in steel. As long as there is enough carbon, they can form their own carbides under appropriate conditions, or they will enter solid solution in atomic state at high temperature. Manganese, chromium, tungsten and molybdenum are carbide-forming elements, some of which enter solid solution in atomic state, and the other part forms cementite of substitutional alloy; Aluminum, copper, nickel, cobalt, silicon, etc. It is an element that does not form carbide, and usually exists in solid solution in atomic state.
