Engaged in Tungsten Alloy Products

Zhuzhou KJ Super Materials Co., Ltd. (formerly known as Zhuzhou Southwest Tungsten Alloy Co. Ltd), can be traced back to 2001 which is a limited liability company engaged in manufacturing, machining and sales of tungsten heavy alloy, tungsten copper, cemented carbide, pure tungsten and other relevant tungsten alloy products.
Offering Wide Product Range
Our main products include Wolfram,Tungsten,Tungsten Alloy, Tungsten Shot,Fishing Sinker,Tungsten Balls,Tungsten Cubes, Radiation Shielding,Syringe Shield,Bucking Bar,Tungsten Points for Archery,Copper Tungsten,Tungsten Crankshaft,Tungsten Spheres,Tungsten Alloy Swaging Rods, Boring Bars, Collimators and Counterweights, which are popular in the US, Canada and Japan.
We offer high-quality products for customers in China and abroad. Our products have characteristics of high density, high hardness, high melting point, anti-corrosion, radiation protection, nontoxic and environment-friendly. Therefore, our tungsten alloy products are widely used in fields of aerospace, medical equipment, military, mechano-electronic, oil exploration, vehicle, sports counterweight and gold-plated jewelry.
Lead by Materials Science Professors and Senior Engineers
With strong foundation, advanced manufacturing technology, strict quality control, and a professional research and development team lead by material science professors and senior engineers, we gain support from relevant academy of Central South University and foreign advanced technology. In addition, we own more than 40 patents for invention and product appearance which ensure our tungsten alloy products are in the leading level in domestic and international markets.

Tungsten Ammo

Tungsten alloy Military properties: high density (60% denser than lead and much denser than steel), high temperature resistance, high melting point, excellent hardness (40HRC, tungsten alloy rod between 26HRC and 30HRC), good corrosion resistance, superior wearing resistance, high ultimate tensile strength (1200MPa~1400MPa), non-toxic and environmentally friendly, etc. Apart form these tungsten alloy properties, tungsten alloy also has military properties. Tungsten military properties: high velocity, long hitting the distance and good accuracy, etc.

Tungsten Radiation Shielding

With rapid development of medical science, more and more tungsten radiation shieldings are used in our lives. Medical instruments x-ray and nuclear power stations have become widespread and are now affecting all our lives. It is essential that people paid more attention to radiation and even more important for the institutions to protect public from the radiation exposure and to make sure to protect every radiation source of X-ray radiation, gamma radiation (energetic electromagnetic radiation), radiation of alpha particles (helium atoms) beta particles (electrons) and cosmic radiation, etc.

Tungsten Bucking Bar

The best price,the high quality, the most complete specifications of the tungsten bucking bars are from Zhuzhou KJ Super Materials Co., Ltd. Tungsten bucking bar are placed behind work surfaces to provide a backing member in applying impact fasteners and including intermitted tool head and handle parts with a low-recoil impact-absorbing spacer provided there between to take shock loads in compression and shear. A rivet gun is a type of tool used to drive rivets; nearly all rivet guns are pneumatically powered.

Tungsten Crankshaft Balancing

Tungsten alloy crankshaft Balancing, sometimes casually abbreviated to crank, is the part of an engine, which translates reciprocating linear piston motion into rotation. A crankshaft is a part that connects to the piston rods and the flywheel of a car. It changes the motion of the pistons to power the vehicle. The crankshaft is the part that will makes the piston motion rotate. This engine part connects to the flywheel, and uses crank throws that connect the connecting rods to the cylinders.

Tungsten Fishing

Tungsten alloy fishing sinkers are weights used to force a lure or bait to increase its sink rate , anchoring ability, and casting distance. Tungsten alloy fishing sinkers may be as small as 1/32 of an ounce for applications, even smaller for fly-fishing applications. They can get as large as several pounds or considerably more for deep-sea fishing. They are formed into nearly innumerable shapes for diverse fishing applications.Unlike lead, environmental concerns do not surround the usage of tungsten alloy fishing weight materials.
