1 . Factory introduction

We are a professional manufacturer of nickel base alloy, Hastelloy alloy, tungsten carbide alloy, cobalt base alloy and H.I.P liner sleeve.

 

We have provided super wear-resistant high corrosion resistance bushing for many domestic and foreign parallel twin-screw extruder customers and modification enterprises, and can be developed according to customer needs, combined with the actual conditions of high quality non-standard products, Oze product performance is excellent, stable quality, reasonable price, timely delivery, perfect after-sales.

 

At present, the factory area of the company is over 3000 square meters, and another 3000 square meters are under planning and design, covering the complete production process of material research and development, main parts production and testing. The company has 6 technical personnel, more than 40 front-line workers, a number of Taiwan, Germany imported production and testing equipment. Currently there are two production plants in China.

 

 

 

 

2 . Properties of Nickel-Chromium-Tungsten Alloy

Nickel-Chromium- Tungsten alloy has excellent abrasion resistance and corrosion resistance. The increase of Cr content in the nickel-chromium alloy matrix contributes to the oxidation resistance, high temperature resistance and corrosion resistance of the alloy. At the same time, the addition of CrB is better than WC. The microhardness of CrB is as high as 4000-4200DPH, which is close to diamond. It is more conducive to improving the overall strength of the alloy. Due to the high density of WC, it is about 15.7g/cm3, while the matrix of nickel-chromium alloy is only about 8g/cm3. The melting is caused by the uneven surface and depth of the alloy due to the easy segregation of WC, so the content and particle size of WC must be controlled.

Nickel-Chromium-Tungsten alloy( we call WJ65) hard phase increased to about 50%, OS02 and OS25 only ten to thirty,Moreover, the fusion is not sufficient, and the microscopic pores are relatively obvious, which is reflected by the Rockwell hardness HRC of only 52-55 While the Rockwell hardness of nickel chromium tungsten alloy (WJ65) is HRC56-64, the conventional control is HRC58-60. The service life is 3-5 times longer then WR5 or CPM10V Nickel-Chromium-Tungsten alloy( WJ65 )on the basis of Ni60 in accordance with foreign

twin screw working conditions of the formula, greatly improved Hard phase carbides (containing tungsten carbide chromium carbide and other carbides), and the nickel pool fullDissolve. Our Ni-Cr -W alloy layer can reach HRC64 is the best proof.
