Tungsten Wire Preformed Corners This is an essential material for manufacture of Electrically Wired Preformed Corners, also called Die-cuts, are used within laminated Heated Windscreens. It is used as the near-invisible heating element glass on the corners of the screen. Usually the busbar can be folded in within the glass viewing area, and is the obvious choice due to excellent order to meet the contour of the screen, but as they are becoming tensile strength (even at very high temperatures) and good corrosion more curved this folding can create a lot of stress on the glass leading resistance. to cracking and increased failures.

    Continuous Wire and Strip Tinning - Product Guide Copper Wire Tinning The acidity of these fluxes comes from organic acid, as a result it is much less corrosive to tinning equipment than inorganic acid and zinc chloride based fluxes. They leaves minimal, zinc-free residue in the tinning pot after tinning. Superior No. 462 is a zinc-free, halide- activated, organic acid type flux for continuous tinning of heavy gage copper wire and strip. Superior No. 460 is a zinc-free, halide- activated, organic acid type flux for high speed continuous tinning of intermediate gage copper wire and strip. Superior No. 461 is a concentrated zinc- free, halide-activated, organic acid type flux for high speed continuous tinning of fine gage copper wire and strip. Steel Wire Tinning Theses fluxes contain zinc chloride, ammonium chloride, and hydrochloric acid for the very demanding operation of continuously tinning to steel. These fluxes are active at room temperature where it begins to clean metals and remove oxides. Superior No. 74 is a zinc-based, inorganic acid type flux. The fluxing ingredients of this product offers a high degree of fluxing activity in the soldering and tinning temperature ranges for steel wire tinning.

  • Re-Tinning Components for Hi-Rel Assembly
    Hi‐rel Soldering Re‐tinning Components for Hi‐Rel Assembly Alan Cable, President, ACE Production Technologies Lead tinning has experienced a surge in popularity recently for a number of reasons, even though the process has been in use for nearly 25 years. The original need arose when the military decided that plated finishes – which are not fused – were not suitable or acceptable for Hi‐rel environments. The problem, at the time, was that plated finishes were found not to be robust enough to withstand oxidation encroachment to the base lead, and could result in a solder joint failure in the field. That process gradually diminished in necessity over the years, but now it has come back for that reason as well as for others. So there are essentially five reasons for re‐tinning: Convert Sn/Pb components to RoHS Refurbishing of “Legacy Components” ‐ Removing the oxidized (plated) lead finish and replacing with a fused intermetalic Sn/Pb finish. Gold Embrittlement Mitigation: Removing the gold from the components leads by “solubilizing” in molten Sn/Pb solder. Tin Whisker Mitigation: Replacing the tin plating with fused alloy. Convert RoHS components to Sn/Pb In the first instance, we remove or change the finish on a needed component, when that component is not available, off the shelf, with the correct or specified finish allow. For example, let’s say I'm building a Hi‐rel assembly that's put together using traditional lead‐bearing Sn63 alloy. Unfortunately, one of the components that I need to use in that assembly is only available in a RoHS‐compatible finish, in this case, electroplated tin.

  • SHEETMETAL FABRICATION TECHNICAL TIPS for SOLDERING Flux
    SHEETMETAL FABRICATION TECHNICAL TIPS FOR SOLDERING Flux In metallurgy, a flux (derived from Latin fluxus meaning “flow”), is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both metallurgy and metal joining. In high-temperature metal joining processes (welding, brazing and soldering), the primary purpose of flux is to prevent oxidation of the base and filler materials. Tin-lead solder (e.g.) attaches very well to copper, but poorly to the various oxides of copper, which form quickly at soldering temperatures. The role of a flux in joining processes is typically dual: 1. As cleaning agents, fluxes facilitate soldering by removing oxidation from the metals to be joined by dissolving the oxides on the metal surface, which facilitates wetting by molten solder. The flux also acts as an oxygen barrier by coating the hot surface, preventing further oxidation during the soldering process. 2. Additionally, flux allows solder to flow easily on the working piece rather than forming beads as it would otherwise. In some applications molten flux also serves as a heat transfer medium, facilitating heating of the joint by the soldering tool or molten solder. FLUX TYPES There are two types of fluxes used for soft soldering. These are organic (rosin based) fluxes or inorganic fluxes, usually based on halogenides and/or acids. Common fluxes are: ammonium chloride or rosin for soldering tin; hydrochloric acid and zinc chloride for soldering galvanized iron (and other zinc surfaces); and borax for brazing or braze-welding ferrous metals.

  • Grounding with Copper: Tinning Vs. Non-Tinning
    Grounding with Copper: Tinning vs. Non-tinning www.copper.org Grounding with Copper: Tinning vs. Non-tinning General Copper and copper alloys are widely used because they combine unique properties at an economical price. These include high thermal and electrical conductivity, ease of manufacture, high recyclability and good corrosion resistance. Copper, a noble metal that occurs naturally in its elemental form, is almost totally impervious to corrosion from Fig. 1. Bare 4/0 AWG parallel copper conductors soils found worldwide. But it would be are prepared for direct burial to form two ring grounds around this wind-powered generator misleading to infer that copper will not base. Soil analysis indicated that bare copper was corrode. entirely appropriate at this site for direct burial with no corrosion concerns. Corrosion Galvanic corrosion is an electrochemical process whereby one metal corrodes preferentially to another whenever both metals are put in electrical contact and immersed in an electrolyte. What is surprising to some is that soil or air can be an electrolyte. Underground Copper is the preferred metal for grounding conductors and electrodes. This is not only due to its high degree of connectivity, but Fig. 2. Above-ground use of 4/0 AWG bare copper also its corrosion resistance. In most soils, grounding conductors for coax braids at a copper electrodes outlast alternates such as communications facility.
