The pouring temperature of aluminum is approximately 1380 deg. F. Pouring temperature is dictated by the fluidity of the particular alloy and the type of casting. Long thin castings require higher temperatures than thick chunky castings. Some metal-casters claim to have good results with temperatures as low as 1250 deg. to 1275 deg. F.

Why does aluminum dross?

This oxide film forms a protective barrier against further oxidation. When melting aluminum, the exposed surface of the molten metal will oxidize to form dross. This dross may float on top, sink to the bottom, or it may become mixed in the melt. If the dross is not ³wetted² by the aluminum it will float. However, if it is wetted, it may become mixed into the melt or sink to the bottom. The specific gravity (weight relative to an equal volume of water) of some of the materials found in dross are listed below.

How does rapid melting reduce dross formation?

Rapid melting reduces the amount of dross formation by limiting the time the melt is exposed to the atmosphere. Melting losses are also higher with ³soaking² or holding the metal at high temperature for an extended time and when fuels are burnt with a large excess of air.
