What Are Materials of Wire Drawing Forming Dies?
Wire drawing dies usually refer to all kinds of dies for drawing metal wires, and also for drawing optical fibers. All wire drawing dies have a certain shape of hole in the center, such as round, square, octagonal or other special shapes. As the metal is pulled through the hole, the size is reduced and even the shape is changed. Screw die manufacturer FENGFENG shows you.

Materials of wire drawing dies
After decades of development, there have been many new materials for wire drawing dies. There are alloys, diamonds and some new materials. The development of new materials has greatly enriched the range of applications and increased the service life of wire drawing dies.
Hexagon Trimming Die
Alloy Steel
Alloy steel die was the early material for wire drawing die manufacturing. However, due to the poor hardness and wear resistance of alloy steel die, short life, can not adapt to the needs of modern production, so the alloy steel die was quickly eliminated, in the current production and processing, has almost no alloy steel die.
Cemented Carbide
Cemented carbide dies are made of cemented carbide. Cemented carbide belongs to the tungsten-cobalt alloy, whose main components are tungsten carbide and cobalt.
Compared with alloy steel dies, cemented carbide dies have the following characteristics: high wear resistance, good polishability, low friction coefficient, low energy consumption, and high corrosion resistance. These characteristics make cemented carbide wire drawing dies have wide processing adaptability and become the most used dies today.
Natural Diamond
The dies made with it have the characteristics of high hardness and good wear resistance. However, natural diamond is more brittle and difficult to process, and is generally used to make wire drawing dies with a diameter of 1.2mm or less. In addition, natural diamond is expensive and in short supply, therefore, natural diamond dies are not the economical and practical wire drawing tools that people eventually seek.
Polycrystalline Diamond
Polycrystalline diamond is made from single crystals of good quality artificial diamond with a small amount of silicon, titanium and other binding agents, polymerized under high temperature and pressure conditions.
Polycrystalline diamond has high hardness and good wear resistance, uniform bore wear, high impact resistance, high wire drawing efficiency, and is much cheaper than natural diamond.
Ceramic material
High performance ceramic materials have high hardness, good wear resistance, chemical stability, high temperature mechanical properties and not easy to bond with metal, etc., can be widely used in the processing of difficult to process materials.
CVD coating
CVD (Chemical Vapor Deposition) coated wire drawing die is a new technology developed recently, and its main method is to coat diamond film on carbide wire drawing die.
Diamond films are pure diamond polycrystals, which have the advantages of both the finish and temperature resistance of monocrystalline diamond and the wear resistance and low price of polycrystalline diamond, and can replace the rare natural diamond.
Wire drawing dies are used in a wide range of applications, such as: high-precision wire materials used in electronic devices, radar, television, instruments and aerospace, as well as commonly used tungsten wire, molybdenum wire, stainless steel wire, wire and cable wire and various alloy wires. They are extremely wear resistant and have a very high service life. Please contact FENGFENG to get the dies you want.
