The above are maximums expressed in percent of total
Others each includes: Bi, Ni, Sn, Zr, V
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 reduction 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 in the
specification tables above are
absolute maximums by heat,
unless otherwise approved in
advance of shipment.
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.
