Menene Rukunin Rukunin Rubutun Aluminum Karfe Mai Haɗin Ruɗi?
Yana da a bimetallic farantin karfe. Layer na aluminum da Layer na karfe suna haɗuwa tare. Tsarin yana amfani da zafi da matsa lamba. Ba a amfani da makamashi mai fashewa. The aluminum and steel are rolled together at high temperature. The bond is metallurgical. It is solid-state. No filler metals. No fluxes. The result is a single panel with the properties of both metals.
How Is the Manufacturing Process Different from Explosion Bonding?
Explosion bonding uses controlled detonation. It creates a wavy interface. The bond strength is very high. But the process is batch-limited. Matsakaicin farantin karfe sizes are smaller. Roll bonding is a continuous process. It can produce longer, wider panels. It is more scalable. The bond strength is lower than explosion bonding. But it is sufficient for many shipbuilding applications. According to a 2022 industry report from the International Clad Metal Association, roll bonded panels achieve shear strengths of 80-120 MPa, while explosion bonded panels often exceed 150 MPa. A cikin ginin jirgi, Ƙarfin da ake buƙata don suturar tsari yawanci 60 MPa. Don haka haɗin gwiwar nadi ya dace da ma'auni.
