Description
Under BGH Edlestahlwerke GmbH group, BGH Feindraht is one of the most important fine wire producers with size range f rom 0.02mm tO 1 .80mm, particually in FeCr and NiCr alloys.
BGH group has full tight control over the whole production process from melting all the way to fine wire drawing. Addition of rare earth element could greatly enhance the key properties of our product as well as improve the life time; and strict control over the production process and purity level gives a good guarantee of our stable quality.
