Brazing porosity
WebA Porosity: Pores in the microstructure less than 10 microns in diameter. Rated from A01 to A08. B Porosity: Pores in the microstructure 10-25 microns in diameter. Rated from B00 to B08. C Porosity: Not true porosity. Rather, carbon porosity consists of discrete areas of graphite in the microstructure resulting from an overabundance of carbon.
