Abstract

A net-formed product of a mixture of copper and tungsten, which has been obtained by powder metallurgical methods with the application of transfer moulding and liquid phase sintering. The product has a very low leak rate in helium gas, high thermal conductivity and a thermal expansion which is essentially the same as in some glass and ceramic material.
