Repair Zinc Die Cast with Super Alloy 1 and Heat Freeze

Repair zinc die cast parts with Super Alloy 1 and Heat Freeze.

An ornamental zinc die cast piece is repaired with a propane torch, Super Alloy 1 low temperature solder and Heat Freeze Heat Paste.  In this clip, a Bernzomatic torch is used to reattach several missing legs from an antique white metal dog statue.

Before soldering, Heat Freeze is utilized to act as a jig, holding the legs in place while they are reattached.

Next, dip the solder rod into the liquid flux and paint the flux onto the area to be repaired.   The flux will transform from a honey color to root beer brown, indicating when to add the rod.  Super Alloy 1 can be used to reattach the missing pieces, then additional solder and flux can be applied as necessary to fill low spots.

Notice how the solder is applied with quick movements in and out to ensure that the soldered legs do not re-melt and fall off.  Heat Freeze can also be used to absorb heat and prevent remelt while working on the remaining 3 broken zinc die cast pieces.

After repairing the zinc die cast part, simply wash the residual flux off with warm water.
