Aceites de soldeo fuerte
Tiras y cortes de láminas de plata y cobre fosforoso para soldeo fuerte.
Nuestras láminas de soldeo fuerte de plata y cobre-fosforoso tienen una superficie de alta calidad con tolerancias de espesor por debajo de los requisitos estándar.
El uso de láminas de plata para unir carburos de wolframio al acero es muy habitual. Las aleaciones que contienen manganeso y níquel son muy populares, sobre todo por sus propiedades positivas de mojabilidad y resistencia, por ejemplo en la industria de las hojas de sierra.
Muchos de nuestros clientes están sacando el máximo partido a nuestra A 338 F, una lámina que contiene níquel y manganeso conforme a la norma ISO 3677. La lámina tiene propiedades comparables en cuanto a intervalo de fusión, resistencia y mojabilidad, combinadas con un menor contenido de plata. Es una alternativa habitual al producto A 324 F.
