A metallurgical composition is provided for making compacted parts, comprising: (a) at least about 80 percent by weight of an iron or iron-based powder; (b) up to about 20 percent by weight of at least one alloying powder; (c) from about 0.05 to about 2 percent by weight of a binding agent comprising a C-Cfatty alcohol; and (d) from about 0.001 to about 0.2 percent by weight of a flow agent.

Metallurgical powder composition

The invention concerns a powder composition including an iron or iron based powder and a lubricating amount of an alkylalkoxy or polyetheralkoxy silane, wherein the alkyl or polyether group has between 8 and 30 carbon atoms and the alkoxy group includes 1-3 carbon atoms.

Iron-based powder

The present invention concerns a metal powder composition for the powder metal industry, wherein the metal powder is selected from the group consisting of an atomized iron-based powder or a sponge iron powder, and a lubricant composition comprising glyceryl stearate.

Metal powder composition including a bonding binder/lubricant

The invention concerns a powder composition including an iron or iron based powder and a lubricating amount of an alkylalkoxy or polyetheralkoxy silane, wherein the alkyl or polyether group has between 8 and 30 carbon atoms and the alkoxi group includes 1-3 carbon atoms.

The present invention concerns a new ferromagnetic powder composition comprising soft magnetic iron-based core particles wherein the surface of the core particles are surrounded by an insulating inorganic coating, and a lubricating amount of a compound selected from the group consisting of silanes, titanates, aluminates, zirconates, or mixtures thereof. The invention also concerns a process for the preparation of soft magnetic composite materials using the new powder composition.

A powder composition for warm compaction comprising an iron-based powder and a lubricant powder consisting essentially of an amide described by the following formula D&mdash;C &mdash;B&mdash;A&mdash;B&mdash;C &mdash;D wherein D is &mdash;H, COR, CNHR, wherein R is a straight or branched aliphatic or aromatic group including 2-21 C atoms; C is the group &mdash;NH (CH) CO&mdash;; B is amino or carbonyl; A is alkylene having 4-16 C atoms optionally including up to 4 O atoms m is an integer 1-10 and n is an integer 5-11.
