The commonly used iron-nickel-copper alloy models are mainly available.
Iron-nickel-copper alloys can be machined by a lathe.
Nickel-copper alloys are mostly used to make parts that require high corrosion resistance, high temperature fatigue resistance, etc., such as traveling wave tubes, magnetrons, etc. ncu28 -2.The alloy is stable in dry gas at room temperature, but it is very corrosive in nitrogen oxides, ammonia, sulfides, and halogens such as chlorine, bromine, and iodine containing water.
In a solution of neutral, alkaline and weakly acidic carbonates, hydrochlorides, sulfates, nitrates, acetates, NCU28-2The alloy is corrosion-resistant; However, when the above-mentioned media contains chloride salts of iron, copper, tin and mercury, the corrosion rate is accelerated. Conversely, it slows down when chromate and glucose are present.

Nickel-iron alloys are all alloys. The main components of ferronickel are nickel and iron, and also contain impurity elements such as CR, SI, S, P, and C.
Ni-iron alloy 36 is a special low-expansion iron-nickel alloy with an ultra-low coefficient of expansion. Among them, the control of carbon and manganese components is very important. Cold deformation reduces the coefficient of thermal expansion, and heat treatment in a specific temperature range stabilizes the coefficient of thermal expansion.

1. Laser cutting, thermal processing, all aspects are ideal, that is, the cost of equipment is relatively high, not all enterprises have the ability to bear, and this method is also powerless for thick metal materials.
2. Plasma cutting: thermal processing, plasma cutting is to use compressed air as the working gas, with high-temperature and high-speed plasma arc as the heat source, to partially melt the metal that will be cut and cut off, and use high-speed air flow to blow away the molten metal to form cutting. The disadvantages are very obvious:
The heat-affected zone is large, the plate will be deformed due to heat, and the loss of cutting gap width is large rapidly, which is not suitable for cutting thin plates.
3. Waterjet cutting: cold processing, the rest is water cutting, the so-called "waterjet", destroying Changling is to use a high-pressure pump to pressurize the sealed water, through the high-grade cemented carbide, sapphire, diamond, etc. made of the nozzle of the extremely fine nozzle to spray out, cutting materials.

Iron-nickel-cobalt alloy is a high-strength, high-temperature, corrosion-resistant alloy material with excellent physical and chemical properties, and has been widely used in aerospace, nuclear industry, chemical industry and other fields. Due to its complex composition and dense structure, iron-nickel-cobalt alloys are difficult to process, requiring special processing equipment and technology.
The processing properties of iron-nickel-cobalt alloys mainly depend on their alloy composition, grain size, heat treatment state and other factors. Once hail, iron-nickel-cobalt alloys are difficult to cut, drill and mill and other machining processes, and often require the use of high-speed cutting, cemented carbide tools, liquid nitrogen cooling and other special technologies and equipment to achieve efficient and high-precision machining.
In addition, iron-nickel-cobalt alloy also has defects such as easy fracture and hot cracking, and it is necessary to pay attention to controlling temperature, cutting speed, cooling method and other factors during processing to avoid processing defects and problems affecting material properties.
To sum up, iron-nickel-cobalt alloys are difficult to process and require special technology and equipment. In the process of processing, it is necessary to pay attention to the control of various processing parameters to ensure the processing quality and the physical and chemical properties of the finished product.

Hello, the cutting method of copper-nickel alloy wire can choose different methods according to the actual needs, and the following are some common cutting methods:1Shear method:
Use special scissors or a mechanical cutter to make cuts. This method requires a very sharp knife and ensures that the cutting force is not excessive. 2.
Welding oak beam cutting method: use oxyacetylene blowtorch, plasma cutting machine and other thermal cutting equipment to cut carefully. Due to the different melting points and chemical properties of copper and nickel, special welding techniques and gases are required.
3.Laser cutting: Use a CO2 laser or ND:
Laser equipment such as yag lasers for cutting. This method has a high cutting speed and high precision, but it requires a high investment in equipment costs. 4.
EDM method: The EDM principle is used for cutting. This method is suitable for alloy wires with higher hardness.
It is necessary to choose the appropriate cutting method according to the specific situation, and at the same time, pay attention to safety during operation to avoid improper operation, resulting in personal injury or equipment damage.

Copper-nickel alloy wire cutting method can be used cutting machine, gas cutting or cutting machine. The cutting machine can be used for copper-nickel alloy wire cutting, it usually has a guide slider and a top plate, driven by the motor, the copper-nickel alloy wire is constantly extended and moved in the knife cutting, the sharpness of the cut and the smoothness of the surface, all depend on the quality of the blade and the angle of the blade used. The principle of gas cutting is to use high-fuel gas mixtures (such as hydrogen sulfide, acetylene and oxygen) through pressure control and flame control to form a directional combustion heat flow, so as to achieve the effect of cutting surrounding substances at high speed.
This method is capable of cutting copper-nickel alloy wires. The cutting machine uses a variety of processes such as upper and lower cutting, pressure cutting and cutting, and uses pulse discharge or high temperature to cut copper-nickel alloy wire. The cutting machine is divided into two molds, one of which is equipped with a cutter and driven by a motor; When the material to be cut is put into the mold, the cutter on one mold will move, and the cut material will be cut from the other mould to complete the cutting task.
In addition, laser cutting is also a cutting method suitable for copper-nickel alloy wire, the principle is to use a pulsed strong beam of light to focus on the surface of the material with high energy to generate heat, when the laser irradiates the surface of the material, the material is violently melted and evaporated along the laser irradiation trajectory, so as to complete the cutting process. There is no need to install extra knives with laser cutting, and Qi Hail can reduce the replacement of knives and greatly reduce processing costs, so laser cutting is a high-efficiency cutting method! <>
