You can be confident that wire from MTS has been consistently manufactured to the highest standards and will perform consistently well. Refining tungsten from ore cannot be performed by traditional smelting since tungsten has the highest melting point of any metal. Tungsten is extracted from ore through a series of chemical reactions. APT can be sold commercially or further processed to tungsten oxide. Tungsten oxide can be roasted in a hydrogen atmosphere to create pure tungsten powder with water as a by-product.
Tungsten powder is the starting point for tungsten mill products, including wire.
Pressing - Tungsten powder is sifted and mixed. A binder may be added. A fixed amount is weighed and loaded into a steel mold which is loaded into a press. The powder is compacted into a cohesive, yet fragile bar. The mold is taken apart and the bar removed.
