Elemental Analysis of MBF601 Braze Joint
–Failure analysis completed on brazed plate heat exchanger
–Example of braze joint that exhibits excellent burst pressure
–Contact points show very little intermetallics
–High Cr in braze joint for added corrosion resistance
–Very little phosphorus diffusion into parent material
SUS444 1050/1150℃-5min in vacuum
SUS316L 1050/1150℃-5min in vacuum
Applications for MBF67 and 601
Automotive
- Applications: EGR Coolers, Heat Collectors, Oil Coolers, Metallic Catalytic Converters
Industrial
- Applications: Water heater, refrigeration heat exchangers
