| TITLE | Method of producing wire from Cu-Ag alloys |
|---|---|
| DESCRIPTION OF THE SOLUTION | The object of the invention is a method for producing wires, including microwires, from Cu-Ag alloys, especially from Cu alloys with (3÷7.9)%Ag content by weight. These alloys, obtained in the form of bars in a continuous melting and casting line, are subjected to appropriately selected heat treatment sequences and a drawing process producing wires characterised by excellent mechanical and electrical properties. |
| BENEFITS OF THE SOLUTION | A consistent and integrated method for the production of finished Cu-Ag alloy bars characterised by high chemical purity and structure, consistently over the entire length of the casting. Ability to shape a set of high electrical and mechanical properties of the final product. Reduction in manufacturing costs through appropriately selected thermo-mechanical treatments. Ability to select the optimum conditions of the thermo-mechanical treatment sequence to achieve the required strength and electrical properties. Favourable weight ratio in relation to the strength parameters of the products obtained. |
| AREA OF APPLICATION | Power engineering (power transmission, conductive materials in power applications), materials engineering, equipment design |
| TECHNOLOGICAL READINESS LEVEL | 9 |
