Class Information
Number: 428/547
Name: Stock material or miscellaneous articles > All metal or with adjacent metals > Having metal particles > Having composition or density gradient or differential porosity
Description: Subject matter in which the porosity in one portion of the material or article differs from the porosity in another portion of the material or article or in which the composition or density of the stock-material* varies gradually from being of one composition or density to being another composition or density, without the formation of distinct layers during the variance, or wherein such variation takes place within a single component of a composite.
