Slowing auto sales may boost Al can sheet output

The trend of US aluminum rolling mills turning away from longtime staple product can sheet in favor of higher-margin automotive body sheet may be cut short as auto sales slow.

The runup in US auto sales in recent years has received much of its support from a massive expansion of credit to buyers, which points to potentially fragile further growth, Regional Metal Services president Garey Rittenhouse said at an major aluminum conference this week in Florida. Leading the charge was an expansion of sub-prime lending to keep up with auto sales, he said.

"To sell the amount of vehicles we do today, they had to go deeper down into the credit pool," Rittenhouse said.

Average US vehicle financing surged by 26pc between 2012 and 2019 while US automotive debt ballooned to $1.2bn from $797bn between 2008 and 2019, he said.

But US auto sales have been slowing from record highs in recent years, with the December seasonally adjusted annual rate declining to 16.7mn light vehicles from 17.4mn vehicles a year earlier. Major auto original equipment manufacturer (OEM) Magna International forecast 2020 auto production to be flat with 2019.

"I expect the margins associated with [aluminum] panels in the automotive sector to come under pressure during the next downturn," Rittenhouse said. "This in turn may bring about some changes in how the flat-rolled sector allocates production capacity, and this brings us to a place where can sheet, once again, may become a better part of the mix."

In 2014, Ford announced its first aluminum intensive F-150 truck, which resulted in four domestic rolling mills and one prospective mill entering the automotive body sheet market.

While many mills continue to produce can sheet, the emphasis on new investment clearly shifted to favoring automotive sheet, which has a higher selling price because it is more highly engineered than can sheet.

Market participants are closely watching US automotive body sheet maker Arconic in particular, with some expecting the company to return some of its rolling capacity to can sheet in 2021.

Argus assessed spreads for can sheet raw material used aluminum beverage cans (UBCs) at 56-58pc of the Midwest transaction price this week, little changed from the same week in 2019.
