Our company was established in oct. 2001 which with joint-venture background. We specialize in manufacturing none-toxic tungsten high-density alloy fishing sinker, golf attached weight item, tungsten watchband, tungsten alloy ball and various tungsten carbide products. We boast abundant fund, advanced manufacture process, strict quality control system even technology support from well-known university. All the above make our products very popular in Japan, u. S. A and other overseas markets. Our products are produced by MIM and pressing technics which can make us manufacture special heavy alloy products and the big parts for medical shield and etc.
Our high-density tungsten heavy alloy production strictly follows the China aviation material standard and u. S. A. Aviation material standard. At present, we offer none-toxic, high density fishing fall, tungsten heavy alloy ball, round stick, golf head, off-centered dipole and other abnormal units. And the production capacity is more than 200t/year. We are one of the few professional manufacturers of high density alloy in China.
Copper tungsten alloy: Production capacity reaches above 100t/year. As one of the important manufacturers of high-quality copper tungsten alloy in China, we can produce all w (50) ~ w(90)series.
Tungsten carbide products: Round stick, ball, welded blade, machine insert blade, wire-drawing mould, mine tools, etc. The annual production capacity is 200 tons.
We own a enthusiastic r & d team leaded by material science professor, higher- grade engineer and also keep a close cooperation with central-south univwersity as well as other relevant institutes to guarantee a leading level in high quality tungsten heavy alloy, copper tungsten alloy, tungsten carbide fields.
Standardization and continuous improvement is the very work criterion we always adhere to while achieving the best to meet customers' need or over the customer's expectation is the greatest happiness to all staffs.
We will provide best price and best service with best quality products for you, so we really expect sincere cooperation between both of us in the coming future!
