"Money can't buy happiness -- but somehow it's more comforting to cry in a CORVETTE than in a Kia"
I read somewhere else that it was called pot metal because it was a cheap alloy used for making pots. I run into it a lot on my 1929 Chevy--it doesn't repair well and is used on the ignition and door locks to name a few...Pot metal—also known as monkey metal, white metal, or die-cast zinc—is a colloquial term that refers to alloys of inexpensive, low-melting point metals that manufacturers use to make fast, inexpensive castings. The term "pot metal" came about due to the practice at automobile factories in the early 20th century of gathering up non-ferrous metal scraps from the manufacturing processes and melting them in one pot to form into cast products. A small amount of iron usually made it into the castings, but too much iron raised the melting point, so it was minimized.
There is no metallurgical standard for pot metal. Common metals in pot metal include zinc, lead, copper, tin, magnesium, aluminium, iron, and cadmium. The primary advantage of pot metal is that it is quick and easy to cast. Because of its low melting temperature, it requires no sophisticated foundry equipment or specialized molds.
