Alloyed copper products are tailor made for customer needs
Luvata’s CuZr (C15000), CuCr1Zr (C18150) and CuNiSi products can be tailor made to customer needs. CuNiSi alloys are a group of different compositions that match with for example these standard alloys: C18000, C70260, CW111C. Our flexible manufacturing operations and unique tool room allow a large selection of sizes and shapes to be made from all these alloys. All these alloys are excellent for hot forming and in some cases further cold working can be used to improve mechanical properties. Read more about our customized copper alloy products.
Multiple application opportunities in various industries
These copper alloys are precipitation hardening alloys that have their unique properties made by aging heat treatment. Combination of high temperature hardness and high conductivity is typically needed in welding applications and electrical motor and generator components for the most demanding applications. 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.
Our focus is in continuous development
- electrical motors and generators
- casting moulds
- welding materials
- commutators
- other applications where high conductivity and good resistance to softening are needed
High temperature alloys are manufactured with many different processes. They are available in various shapes and sizes.
