      Best used for
      •  Bench Work
      •  Casting
      •  Rolling

      Hints, Tips & Uses
      •  Multi purpose Nickel alloy, which is magnetic
      •  Always ensure Nickel is mixed thoroughly
      •  Plasticity and workability is good for bench and rolling when the metal is annealed and allowed to cool slowly
      •  The Nickel content conforms to International standards
      •  Anneal & air cool slowly

  • Tips for Soldering
    • TIPS

      •  Make sure both sides fit perfectly (flush) & that the surface area is large enough.
      •  Remove the burr (that is filings and saw blade damage). Use some sandpaper.
      •  Keep solder edges absolutely clean fat & grease free.
      •  Make sure Flux & the Flux Brush are clean. Do not apply dirty flux to soldering area. Clean flux brush regularly.
      •  Leave a slight gap between solder edges for solder flow.
      •  Flux solder edges & place solder strategically.
      •  Use correct amount of solder.
      •  Set flame correctly & heat evenly. Distribute heat correctly (both sides of piece must reach flowing temperature of solder together).
      •  Never concentrate flame on the joint only – Solder will only flow properly when heat distribution is correct.
      •  Do not stretch solder further than it will or can go – it will cause overheating & destruction of the solder composition.
      •  If solder does not flow or stops flowing – STOP! Clean and start again. Be very careful NOT to leave acid residue in the seam.

      TECHNIQUES

      •  Preplacement: Small pieces of solder are placed at the joint seam prior to heating
      •  Heat is then applied until the solder flows to the joint
      •  Feeding: The fluxed joint is heated to temperature and tip of the solder wire is fed into the joint and should melt on contact
