High-temperature strength. Free-flowing. For carbides, stainless steels, tool steels, and nickel alloys. Excellent wetting of carbides, stainless steel and copper. Good gap-filling at lower brazing temperatures. Fluxless brazing possible in vacuum or suitable atmosphere. Brazing often done together with heat treatment. 87: 10: 2: Cu 87.75 Ge 12 ...
Vacuum furnaces is a relatively economical method of oxide prevention and is most often used to braze materials with very stable oxides (aluminum, titanium and zirconium) that cannot be brazed in atmosphere furnaces. Vacuum brazing is also used heavily with refractory materials and other exotic alloy combinations unsuited to atmosphere furnaces ...
Hudson Yards is located within two primary ZIP Codes. The area south of 34th Street is in 10001 and the area north of 34th Street is in 10018. [158] The United States Postal Service operates the RCU Annex Station post office at 340 West 42nd Street. [159]
A better choice for vacuum systems is the tin-silver eutectic, Sn95Ag5 (Sn-Ag eutectic is actually 96.5-3.5); its melting point of 230 °C (446 °F) allows bakeout up to 200 °C (392 °F). A similar 95-5 alloy, Sn95Sb5, is unsuitable as antimony has similar vapor pressure as lead. Take care to remove flux residues.

Operating a vacuum heat treating furnace, c. 1959–1962. A vacuum furnace is a type of furnace in which the product in the furnace is surrounded by a vacuum during processing. The absence of air or other gases prevents oxidation, heat loss from the product through convection, and removes a source of contamination.
The abbreviation is not always a short form of the word used in the clue. For example: "Knight" for N (the symbol used in chess notation) Taking this one stage further, the clue word can hint at the word or words to be abbreviated rather than giving the word itself. For example: "About" for C or CA (for "circa"), or RE.
Induction brazing is a process in which two or more materials are joined together by a filler metal that has a lower melting point than the base materials using induction heating. In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current from an induction coil .
