The overall density of sintered tungsten tube from Luoyang Achemetal Co., Ltd. is more than 18 g/cm3 . And the purrity of our sintered tungsten tube is better than 99.95%.
Luoyang Achemetal Co., Ltd. has complete equipments for testing physical properties. Here we can test density, hardness, surface roughness, grain size, tensile strength and other parameters of our products. With special equipments we can precisely get the overall dencity of the lage tungsten tubes, which may reflect the real performance of the tungsten tube. The possible interal injury of tungsten tube such as porosity, slag and cracks are doubly strictly inspected with eddy current and ultrasonic equipments by us to ensure the quality of our tungsten tube.
Luoyang Achemetal Co., Ltd. can produce 30 lage tungsten tubes (diameter>200mm) every month. With their excellent quality the Tungsten crucibles were continiualy sold to Russia, Ukraine, United States, South Korea, Japan, Taiwan and China mainland.
