Tungsten-cobalt carbide stud has the advantages of wear resistance and high hardness, but the anti-shear ability is slightly weak. There will also be damage in the process of use, such as fracture or accelerated wear and tear. In the production and operation of the studded-roller, the studded-roller is subjected to severe high stress abrasive wear, shear force damage and long-term fatigue damage. In the operation process, the studded-roller will fracture, peel off and serious wear problems, thus affecting the output and service life of the roller press. The common reasons for the damage of tungsten cobalt carbide stud are summarized here. Read More

If the hard alloy dynamic sealing ring is too tight, it is harmful and useless. First, it aggravates the wear between the sealing ring and the shaft sleeve, and causes premature leakage. Second, it increases the resistance of axial adjustment and movement of the moving ring, so it cannot be adjusted timely when the working condition changes frequently. Three is the spring overfatigue easy to damage; Fourth, the moving ring sealing ring deformation, affect the sealing effect. Read More

Tungsten alloy shielding parts are made of "high density alloy" - mainly tungsten as the main body, adding a small amount of nickel, cobalt and other elements, high density, strong hardness, environmental protection, non-toxic, radiation resistance, such excellent performance, so that the high proportion of tungsten alloy shielding parts in the medical field has a wide range of applications. Zhuzhou Jinxin can design and produce tungsten alloy shielding parts of special specifications and high quality according to different needs and specific scenes, to prepare different product characteristics, customized requirements, and solve enterprise troubles.

For fishing enthusiasts who like long-distance casting, Zhuzhou Jinxin has developed a solid tungsten high specific gravity luminous fishing sinkers ​after conducting tests, this fishing sinker has the following characteristics. Read More

When the production of large quantities of enterprise workpiece, it is more in need of high life die, and wear resistance is an important factor to determine the life of the die. The wear resistance of commonly used stamping die steel is in order of carbon tool steel - alloy tool steel - matrix steel - high carbon and high chromium steel - high speed steel - steel bonded hard alloy – tungsten carbide. It can be seen from the ranking that steel-bonded hard alloy and cemented carbides are the top wear resistance materials. So you can consider the choice of cemented carbide which hardness and wear resistance higher than all kinds of mold steel. Read More

Zhuzhou Jinxin cemented carbide plate, using high-quality raw materials, have high purity, less impurity content; Using new formula proportioning materials, over pressing sintering, plate density uniformity, density is excellent. Using cryogenic processing technology, so that the internal metallographic structure of the plate has been improved, the internal stress can also be greatly eliminated, to avoid the production of cracks in the cutting process of the plate. Used for making blanking die. To be applied to the production of blanking copper, aluminum, stainless products with high temperature hardness, good wear resistance and corrosion resistance, stable physical and chemical properties, good quality, loved by customers from all walks of life.

Centrifugal pump is the centrifugal force generated when the impeller rotates to transport liquid pump. To prevent leakage of fluid or solid particles from adjacent joint surfaces and to prevent external impurities such as dust and water from intruding into the internal parts of machinery and equipment. Carbide sealing ring is naturally indispensable. At the same time, the sealing ring, also known as the mouth ring, can reduce the wear between the impeller and the pump shell, prolong the life of the impeller and the pump shell. Read More

Because the cemented carbide seal ring has good hardness, high hardness, good wear resistance, high elastic modulus, high strength and good chemical stability, low impact toughness, low expansion coefficient, features, can solve problems such as hot cracking of mechanical seal ring, the energy efficiency so general advise clients special working medium choice carbide seal ring. Read More

In order to improve the performance of cemented carbide die, many manufacturers will process the cemented carbide die properly. How to reduce the machining defects of cemented carbide die? In this regard, Zhuzhou Jinxin has suggestions! Read More

Tungsten tss ball are also used in shotguns. Shotgun is a hunting weapon, usually a shotgun. The shotgun barrel has a large caliber, and the bullets are shot out of the barrel and scattered into small balls. The power generated by gunpowder acts on each ball. In the past, old lead pellets were used. Metal lead is toxic, and excessive consumption of lead prey will cause certain injury or even death. If tungsten alloy ball bullets were used, there would be no such toxic contamination. Tungsten alloy ball ball is a kind of lead-free ammunition, high hardness, high temperature resistance, environmental protection, has become the most popular hunting gun ball in the eyes of hunters.
