Production technology:
Finely selected raw materials: As the tungsten rhenium wire industry leading enterprises, our company purchase high-quality raw materials, two of which are the main raw materials from the famous large industrial and mining enterprises, Zhengzhou Sanhui company selected from raw materials, strictly controlled the powder particle size, purity, for production of the next step.
Strictly control the production process:
From powder to finished each link, the company is strict in accordance with the requirements of the ISO9001 and ISO14001 standards on the production line.
Strictly control quality inspection:
In order to control the tungsten rhenium wire in the factory before the last pass, the company strictly controls the quality inspection. Through the performance test of tungsten rhenium wire (high temperature performance, tensile strength, hardness, microscope observation and SEM analysis), to ensure that the product is higher than the national standard, do not put a small defect, so that the customer can satisfy with our products.
Tungsten rhenium wire process is as follows:
Mix - sintering - rotary forging - drawing - alkali washing - Inspection – packaging
Packing method:
Each volume 400-600g, 250m-260m per kg, vacuum packaging, outer carton, woven bag.
In recent years, with the rise of sapphire in foreign countries, tungsten rhenium wire produced by our company was widely exported to Taiwan, Japan, Korea, Russia, Ukraine and other countries, mainly for the production of sapphire crystal growth. WR25, diameter 0.5mm is the most commonly used.
