DEFINITION

Classification: 428/558

(under subclass 553) Subject matter in which the nonparticulate metal component serves to enclose, completely or partially, the particulate metal component.

(1) Note. The metal particles often are distributed in a nonmetal matrix of fluxing agent to make a "solder stick".

SEE OR SEARCH THIS CLASS, SUBCLASS:

208, 328 and 330, for a plural layer nonmetallic* sheet or web in which one layer contains metal particles.

559+, for other metallic* composites having metal particles mixed with nonmetal fluxing components.

75, Specialized Metallurgical Processes, Compositions for Use Therein, Consolidated Metal Powder Compositions, and Loose Metal Particulate Mixtures, 303+, for flux compositions, per se, containing metal particles, without a binder.

106, Compositions: Coating or Plastic,

1, for metal depositing, e.g., "hard facing", compositions containing metal particles and a nonmetal binder or carrier fluid, with or without a fluxing component.

148, Metal Treatment,

24, for flux compositions, per se, containing metal particles and a binder or carrier fluid.

219, Electric Heating,

146, for an electrode for arc heating of metal, having a core of a fluxing composition.

228, Metal Fusion Bonding,

56.3, for an article adapted to be applied to work as filler material, subclass 214 for a process of surface-bonding metallic parts using a flux, subclass 244 for such methods

using an unfused (e.g., particulate) metal filler, and subclasses 262.1+ for such method wherein the work component, temperature, or pressure is critical.
