Guys, we gotta pay a little attention here.
1220.58° F Melting pt. of aluminum according to Wikipedia
730°F Melting point of the repair rods according to the FAQ page of the
aluminumrepair.com website.
730°F is (730-32) /9 *5 = 388°C
Steffen, most waxes have some paraffin? 36°C(?) Flashpoint-- at least that's
what they talk about at the turbine-fuel safety demos at the fire dept. at the
airport.
One should be able to control the types of torches they speak about using
without doing damage to the aluminum. You have to keep the flame moving on
large surfaces, because the aluminum distributes the heat so efficiently, but
it appears to be considerably better than anything else I have seen so far.
They even explain the characteristics of exploding gases that make it possible
to use the material for aluminum engine block repairs in spite of the low melt
point.
I wish ya'll a merry Christmas and recommend the story as recorded by Dr.
Lukas' Evangel, chapter 2. joy to the world, peace on earth.
