It is a universal primary blank intended for further processing for making more specific semifinished products (such as sheets or rods) or for further remelting as part of an alloy or steel. The properties of the billet material determine the properties of the end product so the described products play a very important role in production.
Tungsten billets can be purchased on the website of Metotechnics company so as by phone or via e-mail.
Technical parameters of semifinished products and other useful information are given in the corresponding sections on this page. Also product standards that can be found on our website also serve as a useful source of information.
Grades
Billets are made of high-purity wolfram (HPW) and metallurgical wolfram. The first material has a very high wolfram content (at least 99.97%). The second one contains at least 99.32%. Other components (such as molybdenum, stannum, oxygen etc.) are considered to be additives.
The chemical content of the stated materials is given in TC 48-19-57-91 and TC 48-19-76-90 standards.
Production
Wolfram billets are produced as follows:
powder extrusion;
pre-baking;
baking.
The described process allows receiving square-section semifinished products. The section size can vary from 8х8 to 40х40 mm, length - from 280 to 650 mm. There are no requirements towards the extreme tolerances of the size of these products as further they undergo significant processing for receiving standard blanks like rods, sheets, flat bars etc. Due to this wolfram billets are not subject to additional processing like pickling, annealing, polishing etc.
The products should correspond to the requirements of several regulatory documents such as TC 48-19-57-91, TC 48-19-76-90 and etc.
Application
The products have the two following applications:
blank for producing standard semifinished products;
alloying agent for various steels and alloys.
In the first case HPW (high-purity wolfram) is used. The purity of the chemical composition plays a great role for further production of wolfram goods. Billets are used for making rods and sheets that serve as the basis for the rest of the round and flat rolled products.
For the second case a high additive content is not critical as tungsten is one of the components of the produced material so metallurgical wolfram is applied there. Among alloys and steels where this metal is present, heatproof and hard alloys so as instrument steels should be mentioned. Wolfram makes material durable, wear-resistant and heat-proof.
Prices
Wolfram billet of different section and length is available for ordering on the website and is available in Cost section. Also wolfram products and their prices are given there.
