Small quantities may be purchased directly from Alumite.com alumitedata 062802 Page 16-18 Fluxless Soldering with Kapp Alumitetm To solder aluminum, the invisible oxide film must be penetrated by the solder to obtain metal to metal contact. This can be done simply and effectively without flux using Alumitetm. IT IS ONLY NECESSARY TO HEAT THE ALUMINUM TO A TEMPERATURE THAT WILL MELT THE END OF THE SOLDER STICK AS IT IS DRAWN ACROSS THE HEATED ALUMINUM SURFACE. The solid end of the stick punctures and loosens the oxide and allows the solder to creep underneath. Many types of constructions are possible using this fluxless technique; however, it should be noted that THE ALUMINUM SURFACE MUST BE ACCESSIBLE TO STROKING BY THE Alumitetm Otherwise, use Kapp Lunar Flux to remove oxide and draw the solder into blind joints. T JOINTS For maximum strength, tin both members as described above and bring together. Heat the parts and flow a fillet of solder into the intersection. Run the solid end of the solder stick through the molten fillet to remove any trapped oxide. In many instances, adequate strength can be obtained without pre-tinning. Fillets are made by running solder along set-up members where contact is desired, letting the heat from the aluminum, NOT THE FLAME, melt the solder. When the members are not pre-tinned, the fillets alone support the joint load as the members are not joined to each other, but only to the fillets. BUTT JOINTS Ends are beveled and brought together. Follow tinning procedure, stroking both beveled surfaces of the joint (with tinned groove) with Alumitetm. LAP JOINTS Parts can be tinned and slid together while solder is still molten, or a generous fillet of solder can be applied to the edges of the lap joint, making sure of tinning by running stick through molten solder. MITERED JOINTS IN WINDOWS, DOORS, SCREENS, FRAMES Material is solidly jigged. A neutral flame is played over the joint area until Alumitetm will melt when drawn across the joint. Make sure of tinning action by running solid end of solder stick through molten solder deposit. After tinning, the joint may be built up and finished as desired. These joints are stable in the presence of humidity and have remained in perfect condition after many years of exposure. REPAIR AND CHANGE DESIGN OF ALUMINUM MATCH PATTERNS AND DIES The section to be worked is cleaned by filing or grinding, then tinned by heating the aluminum to a temperature that will melt the solder when rubbed on. When tinning, the Alumitetm rod should be kept out of the flame, letting the heat from the aluminum melt the solder. Build up with a soft flame. Pre-heating the entire match plate of the die to approximately 600oF facilitates the operation. TO WELD ZINC BASE CASTINGS WITH AlumitetmRemove plating, natural oxide, or foreign matter from surfaces to be joined. "V" out fracture and set up job solidly. Use #1 or #2 tip to pre-heat area surrounding fracture. Weld is then made by heating fracture directly with neutral flame until surface of base metal can be broken by touching it with Alumitetm rod. KEEP ROD AWAY FROM FLAME AS MUCH AS POSSIBLE WHEN STARTING WELD. Continue welding fracture by puddling the solder in the base metal. NEVER PLUNGE INTO WATER TO COOL. Finish as desired. TO WELD WHITE METAL WITH AlumitetmClean plating or scale from surface to be welded. "V" out fracture and set job up solidly. Pre-heat generally with neutral or acetylene flame. Heat directly until parent metal starts to melt, then dip solder rod in and out of molten puddle to desired build-up. STRIPPED THREADS Drill old threads out over size so when new fillet is added all drilling and tapping will be done in Alumitetm. This will make it easier to work with and will increase strength. After drilling, heat base metal from bottom of hole, up. Tin rod into wall of hole beginning at bottom and work up. Fill hole, cool, drill and tap as needed. KEEP FLAME IN MOTION. ALWAYS USE NEUTRAL FLAME. NEVER PLUNGE INTO WATER. COOL SLOWLY. Alumite joints are permanent, corrosion resistant, & stronger than joints made with other solders. alumitedata 062802 Page 16-18 MATERIAL SAFETY DATA SHEET Page 1 of 3 Kapp Alumitetm Solder for Aluminum, Diecast, Zinc Alloys, Pot Metal and White Metal Trade Name: Kapp Alumitetm Solder Composition: Proprietary Ref.

  • ELECTROLESS NICKEL/Krome PLATING KITS
    Email: [email protected] Web Page: www.caswelleurope.co.uk ELECTROLESS NICKEL/Krome PLATING KITS So simple - just like boiling an egg! The ideal way to plate small parts - easily - economically - quickly. No batteries or power required - simple electrochemical reaction plates automatically. Plates many metals - all steels, irons, copper, brass, bronze, lead free solders and nickel alloys. Plates Aluminium using the Zincate process Plates Pot Metal using Pot Metal Primer Even and uniform plated layer, even in the most difficult corners. Plates @ 1/1000" (25 Micron) per hour Cyanide free - no EPA problems - No fumes No disposal problems - drain safe IMPORTANT! READ ENTIRE BOOKLET BEFORE ATTEMPTING TO OPERATE THE SYSTEM As simple as boiling an egg! These instructions now cover the Nickel and the Krome kits. Electroless Krome is a nickel/cobalt alloy, harder and bluer than nickel. Where these instructions refer to Electroless Nickel, this also means Electroless Krome. The only difference in the kits is the part A component, which, in the case of Krome, has the cobalt additive. You may use parts B & C for either type of plating, as they are completely interchangeable. Electroless nickel/krome plating requires no anodes, power supply or electrical connection of any kind. The process simply involves mixing together some solutions, heating them to just off the boil, and then immersing the part to be plated. An autocatalitic electrochemical reaction takes place and the nickel is evenly deposited all over the part being plated. The thickness of the plate will depend on the duration of immersion. To stop the reaction, the part is removed from the solution, which is allowed to cool before storing for later reuse.

  • Super Alloy 1 Instructions: 1. Pre-Clean the Parent Metal Or Metals to Be Joined. Use Emorycloth, Wirebrush, Bead-Blasting, Etc
    Super Alloy 1 Instructions: 1. Pre-clean the parent metal or metals to be joined. Use emorycloth, wirebrush, bead-blasting, etc. On cracked or broken pieces it is advisable to "v" out cracks and both sides of broken metal to provide strength. 2. Apply the non-corrosive, liquid flux to the repair area. An easy method of application is to dip the end of the rod into the flux. The flux will cling to the rod and is easily spread with the rod. 3. Use a soft flame, heat gun, or soldering iron to heat the parent metal adjacent to the actual repair. A direct flame on the repair area is likely to overheat the solder and flux. Soldering irons lose the ability to heat well on parts thicker than 1/8" 4. Hold the torch tip four to six inches away from the parent metal. If it is necessary to apply the flame directly on the rod and flux pull the torch tip back even further from the work surface and keep the torch moving. 5. The flux will begin to bubble and turn light brown. Besides preparing the parent metal for the solder, these changes indicate the proper working temperature. If the flux turns black, clean-up the area with warm water and a wire brush and start over. 6. When the flux turns brown it is time to apply the rod. Drag the rod over the area to be soldered until it begins to flow and stop applying the heat. If additional layers are needed, continue dragging the rod over the area while applying heat if the rod doesn't melt.

    Metals Chart The following chart gives you an overall concept of which metals can be plated with each kit, and the steps required. To read the chart, pick your base metal type (or current plating type) on the left, then pick the type of plating you want to do from along the top. For example, if you start with a piece of stainless steel, and want to chrome plate it with Copy Chrome, the steps are: 1.Degreaser until it passes the waterbreak test 2.Use Pickle #4 to etch 3.Strike Coat with Flash Copper 4.Nickel Plate (The Copy Chrome Column says "Over Nickel") 5.Copy Chrome Plate Some Notes: -Gold Plating (not shown) should only go over a nickel or tin plate. -Silver Plating (not shown) should only go over a copper, nickel or tin plate. -Hard Chrome Plating (not shown) is usually plated directly over steel parts, or zincated aluminum This chart can also be used to assist with brush plating, however you cannot brush plate over zincated aluminum or conductive painted materials. You should tank plate these materials with copper first, then you can brush plate over the copper.

    Soldering Brazing Welding From Caswell Inc • www.caswellplating.com • 855-CASWELL Introducing our new range of rods for welding, brazing and soldering, especially designed to be compatible with our electroplating kits Aluminum, pot metal, steel, cast iron, stainless, brass and copper We have a system to suit them all Soldering Rod melts below 842ºF. That temperature is defined to be 842ºF/450ºC by the American Welding Society (AWS) but is often rounded to 840ºF. If the filler metal melts below 840ºF, the process being performed is soldering. Metals that can be soldered include gold, silver, copper, brass, and iron and pot metal. The filler, called solder, melts. The base metal does not melt. Brazing Rod melts above 842ºF. If the filler metal melts above 840ºF the process being performed is Brazing. Metals that can be brazed include gold, silver, copper, brass, and iron and pot metal. The filler, called braze, melts. The base metal does not melt. Welding The welding process is completely different from soldering and brazing because both base metals and rod being joined are melted. The temperatures needed to weld various metals are listed here.
