Laser cutting of non-ferrous metals

Due to their high electrical conductivity and good corrosion and thermal conductivity, non-ferrous metals have the ideal prerequisites for the production of electrodes, busbars and leadframes as well as for springs, plug contacts or cell sheets. Our special expertise lies in the procurement and processing of special materials. Non-ferrous metals such as copper, nickel, bronze or nickel silver are ideal for laser cutting and laser welding.

Non-ferrous metals in application

Non-ferrous metals are ideal for connection and transmission functions: Copper and nickel silver, for example, serve as punched or base plates in the production of plastic injection moulded parts with metal cores. Thin metal foil strips of less than one millimetre are usually connected to the actual semiconductor chip as connection frames, so-called lead frames, via wire bonding. Alternatively, they function as contact pins and connector elements for connections of PCB assemblies.

In contrast, solid copper busbars with a material thickness of up to four millimetres are encapsulated directly in the component for use with extremely high current flows and used for mechanical holding functions, for example, by means of pressed-in bolts.

A wide range of processing options for your non-ferrous metals

We cut and weld thin sheets, foils and strips made of copper and other non-ferrous metals according to your individual ideas and wishes. We are happy to process your supplied material or offer you the service of procuring special materials in small quantities without processing them further.
