Manufacture of products using powder metallurgy techniques develops in the direction of development of products made of new perspective materials, expansion of the product range and improvement of the design of machined tungsten-, molybdenum-, chrome-, and
The following powder metallurgy techniques are used in production of metal powders: hydrogen reduction (tungsten, molybdenum powders), reduction of metal oxides by calcium hydride (titanium, chrome,
The company is one of the world’s largest manufacturers of
Molybdenum and tungsten are produced in the form of powder, flat rolled stock, bars, electrodes, forged pieces, complex shape products: crucibles, boats, heating unit parts.
Composite materials are represented by products made of heavy tungsten alloys,
In production of main types of products, Polema uses the ISO 9001:2008 quality management system confirmed by an international certificate.
