Others total includes: Ti, Na, Ca, Cd, Pb, Be, Ni, Cr, Sn, V, Zr, B.

Must be low profile sow or standard T-Bar
All pieces must be marked with heat number

*Preferred Cr<.15, Zn<.30

Element Reporting Requirements for RSI and

primary aluminum are shown below.
Lithium

Material from plants using Lithium in their process is not acceptable.

RSI Sow Heat Variation

Maximum heat variation for all ARCO Specs must be no greater than 150% of the average per element. Heat variation greater than 150% of the average per element will not be accepted without prior approval from ARCO.

Italicized numbers are absolute maximums by heat.

Loading of RSI Sow
Please load heats on truck/railcar in the same order as listed on the COA sheet. This does not apply to prime aluminum.
