  2. Vacuum furnace - Wikipedia

    en.wikipedia.org/wiki/Vacuum_furnace

    Vacuum furnaces are used to carry out processes such as annealing, brazing, sintering and heat treatment with high consistency and low contamination. Characteristics of a vacuum furnace are: Uniform temperatures in the range. 800–3,000 °C (1,500–5,400 °F) Commercially available vacuum pumping systems can reach vacuum levels as low as 1 × ...

  3. Brazing - Wikipedia

    en.wikipedia.org/wiki/Brazing

    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 ...

  4. List of brazing alloys - Wikipedia

    en.wikipedia.org/wiki/List_of_brazing_alloys

    BVCu-1x is OFHC, vacuum-grade, for furnace brazing of steels, stainless steels and nickel alloys. Oxygen-containing copper is incompatible with hydrogen-containing atmospheres which cause its embrittlement. Cheaper than silver, but requires higher processing temperatures and is oxidation-prone. Used in fluxless vacuum brazing of stainless steels.

    Ipsen's industrial furnaces - vacuum furnaces, atmosphere furnaces and pusher-type furnaces - are used for the following heat treatment processes: hardening, quenching, tempering, carburization, carbon nitriding, nitro carburization, bright tempering, annealing, vacuum brazing, temperature brazing, plasma nitriding

  6. Induction brazing - Wikipedia

    en.wikipedia.org/wiki/Induction_brazing

    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 .

    President Joe Biden ordered a national day of mourning in January and flags to be displayed at half-staff following President Jimmy Carter's death.

  8. Materials for use in vacuum - Wikipedia

    en.wikipedia.org/wiki/Materials_for_use_in_vacuum

    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.
