Armor-piercing Capability of Tungsten Alloy Penetrators

Kinetic energy penetrator armor-piercing capability (speed, quality) and artillery material determines their physical properties when the shells hit the target. The kinetic energy depends on the speed and quality at speeds in certain circumstances, be increased to increase the quality of artillery projectile kinetic energy penetrators therefore generally made ​​of high density, hard, high temperature metals. At present the material more widely used is tungsten alloy and depleted uranium, but because depleted uranium has a radiation, so use less.

Promote the progress of science and technology to gradually increase the power of the penetrator. In evaluating the piercing armor-piercing capability, the standard is much more commonly used military homogeneous steel armor piercing mm depth equivalent. In World War II, the most famous German 88MM gun fired projectile can penetrate 200MM homogenous steel armor. Currently, tungsten alloy penetrators German L55120MM caliber tank gun fired homogenous steel armor can breakdown 810MM on the 2000M distance; in China, 99 tanks equipped with a tungsten alloy penetrators 125MM artillery fired on with a 850 mm armor-piercing capability same distance.

Major Research Direction of Tungsten Alloy Penetrators

The development of tungsten alloy penetrators materials has made considerable progress on technology, but there are still some drawbacks. So it  need to study tungsten alloy penetrators in depth :

1: Increase research utilization, scientific environmental aspects of the recovery of tungsten alloys. Strengthen missile recycling tungsten alloy and tungsten scrap cuttings and low raw consumption technology research and development.

2: Strengthening research on tungsten alloy penetrators performance and insulation piercing sensitivity aspects. Armor-piercing shells performance is the most important performance indicators tungsten alloy, relatively few studies in this respect, especially playing board study of the mechanism of action is not deep enough, should also strengthen research adiabatic susceptibility tungsten alloy materials.

3: Research to improve air defense missile systems and armor-piercing capability of damage, enhance the tungsten alloy brittle material and wear Bouncing burning complex functional elastomer material.

4: High Strength Composite armor-piercing tungsten is an important development direction of future ultra high-speed kinetic energy penetrators should be further strengthened with ultra high-speed kinetic studies tungsten penetrator projectile beam composite materials, targeted to carry out bomb with a tungsten alloy corrosion protection technology research.

The Use of a Tungsten Alloy Shield of Nuclear Medicine

Tungsten alloy is excellent material which is used to shield the x-rays and gamma rays . The shield tungsten alloy can be used in the medical field such as shield Brachytherapy and positron emission tomography.

Brachytherapy, also known as in internal exposure. When the human body is difficult to track the tumor tissue ,it can be used to inject (one of brachytherapys ) to replace radiotherapy. Injecting radioactive particles can be accurately placed evenly around the tumor. Before and after treatment, radioactive seeds are stored in tungsten alloy products, so that doctors and patients from harm.

Positron emission tomography (PET) .tracer isotope will be injected to the human body, and brain tissue encounter electrons positron isotope released ,the annihilation effect will occur, resulting in almost the opposite direction of the pair of rays γ- can a special device to be detected, whereby the position of the distribution of the isotope can be obtained, which is a method for diagnostic nuclear medicine techniques. When X-rays illuminate the body structure, PET can show the individual chemical functions of internal organs. PET of DNA to be injected, the injection from the syringe into the patient. As DNA passes through the patient's body, it will release gamma rays, gamma camera lights by chemical activities and internal organs such cells can be seen. Tungsten alloy and tungsten can be applied to PET syringe needle shielding.

What is Tungsten Fishing Bead?

Fishing beads can be as an attractor or be a component of the rig when you are fishing.

Fishing beads can be made from plastic, brass, lead, tungsten and so on. And they come in many different colors.

There are also luminous beads made of plastic which glow in low light when the water you are fishing has low visibility to attract fish.

However, tungsten alloy fishing bead becomes more and more popular because of its good properties.

Tungsten fishing bead is made from tungsten alloy, so some peple call tungsten alloy fishing bead as tungsten fishing bead.

Applications of Gamma Tungsten Alloy Radiation Shielding

Tungsten alloy gamma shield has high-density , the small physical size, high rigidity and the effectiveness of the shielding characteristics,  therefore it has a strong value.Applications of gamma radiation shield tungsten alloy has two main aspects:

1: medicine. Gamma ray is mainly used in the medical and therapeutic drugs to kill certain types of cancer and tumors, but in this process, the gamma ray will inevitably damage other cells in our body. Therefore, we need to control tungsten gamma shield gamma rays.

2: industry. Geological logging tungsten gamma radiation shield: Geological logging is an exploration technology, mainly for the oil and gas industry. It is also known as wire-line logging and well logging. Gamma ray source, and reduce radiation penetrates well into the formation, and then can be analyzed from these data, to determine the presence of gas or petroleum. Tungsten alloy for shielding radioactive sources, but also used in γ-ray collimator. Gamma rays in the industry, for the detection of internal defects of metal castings and welded structures, industrial radiography, industrial radiography using a gamma-ray detector material, commonly used in metal and concrete structures fault, in this case, we need to tungsten gamma shield γ-rays to protect our body. Pipeline patrol lines and tungsten collimator device also uses a tungsten gamma radiation shield.
