Our flexible manufacturing operations and unique tool room allow a large selection of sizes and shapes to be made from all these alloys. We provide quantities ranging from small samples to large orders. Copper Alloys for Demanding Applications CuNiSi alloys are a group of different compositions that match with for example the standard alloys C18000, C70260, CW111C. These copper alloys are precipitation hardening alloys that have their unique properties made by aging heat treatment. They are excellent for hot forming and in some cases, further cold working can improve the mechanical properties. Welding applications and components for electrical motors and generators typically require a combination of high temperature hardness and high conductivity for the most demanding conditions. Good mechanical properties and good thermal conductivity make these alloys suitable for different water-cooled components, such as structural cooling elements and casting and extrusion molds. Aged temper offers also high fatigue resistance and durability for wear and corrosion. Document Library Why Luvata? Luvata’s expertise comes from dedicated processes and strong process know-how.
