It's interesting, I saw a map recently where aluminum ore is mined in Tennessee, then sent to Canada to be forged into a cylinder,
next sent to Mexico to be milled into a piston then shipped to the Midwest somewhere to become a finished piston before going elsewhere for the final assembly of an auto engine.
The chart showed the multiple tariff activity on each trip across our borders. It's hard to comprehend that we can't build the piston here.
This factoid sort of disagrees with the 1st point - Bauxite is the only commercial ore of aluminium, and 96 percent of bauxite consumed in the US is used to produce aluminum (metallurgical grade).
However, since 1981,
NONE of the bauxite mined in the US was used to make metallic aluminium. US bauxite is instead used for abrasives, high-temperature refractory materials, and other
uses in oil & gas industries.
Canada imports virtually all its Bauxite and due to the excess electrical power available can smelt it cheaply and efficiently - hence why its cheaper. So until the US builds many more nuclear and hydro
facilities you won't have a home produced raw Aluminium product. And seeing as you don't have commercial quantities of Bauxite (US production of ore is measured in 10's of 000 tons) you'll still
have to import ore which will be tariffed in this mad 'world order'
And pistons can be produced in the US - there are several 'performance' piston manufacturers in the US that produce both cast and forged pistons - obviously not at volumes required or as
cheaply as off-shore production. This is what it comes down to - US production costs too much and to bring it back within US borders will require a shed load of capital money investment with a
guarantee of required need for next 25-30 years to warrant the cost. Plus labour costs will still make home grown more expensive against imported!
