High-density tungsten alloy is an alloy material prepared by using tungsten as a matrix and adding other metal elements such as Ni, Fe, etc. through a special processing technology. It has the characteristics of high density, high strength, high hardness and high compactness, and is widely used in aerospace, military, oil drilling and other fields. The preparation process, performance characteristics, application fields and other aspects of high-density tungsten alloy will be introduced in detail below.
- Preparation process of high-density tungsten alloy
The preparation process of high-density tungsten alloy mainly includes powder metallurgy, sintering, extrusion and heat treatment. The purpose of these steps is to ensure the compactness and stability of the alloy’s internal structure.
powder metallurgy
Powder metallurgy is one of the key steps in preparing high-density tungsten alloys. First, the tungsten powder needs to be mixed evenly with other metal elements and pressed into a dense compact. In this step, it is necessary to select the appropriate tungsten powder particle size and pressing pressure to obtain a dense compact.
sintering
Sintering is a key link in the preparation process of tungsten alloy. It is a process in which the atoms and molecules in the tungsten alloy block are diffused and rearranged under a certain temperature and pressure to achieve densification. During the sintering process, temperature and time need to be controlled to avoid defects such as pores and cracks.
extrusion
Extrusion is the step of extruding the sintered tungsten alloy billet through a die. Through extrusion, the compactness and stability of tungsten alloy can be further enhanced. During the extrusion process, it is necessary to select the appropriate mold and extrusion speed to avoid cracks and deformation.
heat treatment
Heat treatment is an important step in adjusting the internal structure and properties of tungsten alloy. Through proper heating and cooling, internal stress can be eliminated and the strength and hardness of tungsten alloy can be improved. During the heat treatment process, the heating temperature and cooling rate need to be controlled to avoid defects such as cracks and deformation.
- Performance characteristics of high-density tungsten alloy
High-density tungsten alloy has excellent mechanical properties and physical properties. These performance characteristics make it widely used in many fields.
high density
High-density tungsten alloy has a high density, usually above 18.00g/cm³. This high density gives tungsten alloys excellent weight and structural properties in many fields.
high strength
High-density tungsten alloy has high strength and can withstand large external loads. At normal temperature, the tensile strength and yield strength of tungsten alloy are higher than that of steel. This high strength gives tungsten alloy excellent mechanical properties in situations where it can withstand large loads.
High hardness
High-density tungsten alloy has high hardness and can provide good wear resistance and corrosion resistance. This high hardness gives tungsten alloys excellent properties in terms of wear and corrosion resistance.
High density
High-density tungsten alloy has a highly dense internal structure, which can effectively shield the transmission of electromagnetic waves such as rays and microwaves. This high density makes tungsten alloys have excellent shielding properties in the nuclear industry, aerospace and other fields.
good processing properties
High-density tungsten alloy has good processing properties and can be used for turning, milling, drilling and other mechanical processing operations. This good processing performance makes tungsten alloy have high production efficiency in the manufacturing process.
