CHEMETAL USA specializes in the manufacturing of tungsten heavy alloy sheet. We take pride in offering tungsten heavy alloy sheet with a range of thickness from 0.012″ (3 mm) to less than 0.004″ (0.1 mm). Tungsten heavy alloy sheet contains tungsten content ranging from 80%-98% with small amounts of molybdenum, nickel, iron and copper elements. After going through the mixing, pressing and sintering process, tungsten is combined with the other metal elements beginning as a form of powders. Thanks to our manufacturing team’s hard work and close attention to detail, we are able to keep our strong advantage in the competitive market. The quality received by our customer is guaranteed to have the required flatness, roughness and machinability. CHEMETAL USA is capable of offering various types of Tungsten sheet, Tungsten Heavy Alloy sheet and Copper Tungsten sheet that all meet a consistently high standard of flatness, roughness and machinability. We are also able to provide a fast lead time and handle large-volume contracts. CONTACT US and download our PRODUCT CATALOG to learn more about our Tungsten products.
