Applications
Welding electrodes, electrode holders and seam welding discs in resistance welding. It uses rarerly as plunger tips in Aluminium Die Casting industry. It uses also injection nozzles, cooling inserts in plastic injection industry. Moulds for casting of non-ferrous material. Chill moulds in casting of brass and bronze material. Due to its good surface quality, homogen and fast cooling rate this alloy has an excelent working performance too.
