Aleaciones cromo-niquelLas aleaciones de níquel y cromo-níquel tienen una alta resistividad, buenas propiedades antioxidantes, resistencia a altas temperaturas, gran estabilidad y capacidad de soldadura. Las diferentes aleaciones de cromo-níquel que podemos suministrar son ampliamente utilizadas como materiales de base para la fabricación de resistencias eléctricas, componentes electrónicos y hornos industriales.En función de la aplicación del cliente podemos suministrar tanto alambre de niquel en las diferentes aleaciones cromo-níquel que se indican a continuación como en fleje niquel cortado a medida. El material se entrega en bobinas de plástico de manera que los bordes del fleje cromo niquel quede perfectamente protegido y sea fácil de trabajar para el cliente.A continuación le indicamos algunas de las aleaciones de cromo-níquel que suministramos. En caso de estar buscando alguna otra dispone del formulario de contacto.
