摘要： A method for producing a contact material made of copper and chromium in a proportion of 40 to 75 wt.-% copper and 25 to 60 wt.-% of chromium for contact pieces for vacuum switch devices by pressing the powder mixture, sintering and infiltrating the compact and subsequent reshaping into a semi-finished contact material product having a density which corresponds to at least 99% of the theoretical density, as well as to contact pieces made of this semi-finished contact material product.

摘要： A method for manufacturing a contract arrangement for a vacuum switching tube having a contact carrier and a contact piece joined to the contact carrier in a vacuum using soldering material. The contact carrier is made of electrically highly conductive material, for example, copper, and the contact piece is made of a flame-resistant sintering material containing copper. The contact piece is pressed flat directly onto the contact carrier, generating a gap along the contact surface, and the soldering material is arranged on areas directly bordering the gap of the contact surface between the contact piece and the contact carrier. Subsequently, in a vacuum through the application of heat, the soldering material is brought to the melting point, and the molten soldering material penetrates into the gap of the contact surfaces between the contact carrier and the contact piece.
