Hydro Aluminum suffered an explosion inside the melting furnace at its Henderson, Kentucky, cast house, according to a letter to customers obtained Wednesday by S&P Global Platts.
The letter was signed by Hydro Aluminum President Matt Aboud.
There were no injuries, but the furnace "sustained substantial damage and will need prolonged downtime so we may complete a full assessment and make the necessary repairs," Aboud said about the Tuesday blast. "Our commercial team is already working diligently to evaluate critical customer needs scheduled for the coming days and investigate alternative sources of supply."
Calls to Aboud and the Hydro Aluminum's press office were not returned Wednesday.
Hydro's aluminum remelting facility in Henderson produces more than 90,000 mt of metal annually.
A source close to the situation said Hydro is still working on what they will or will not be able to do for its customers. "I am getting emails from them hourly," he said.
The outage was not expected to affect the billet market, but it is "too soon to tell," he added.
The Platts 6063 billet upcharge was last assessed at 12-14 cents/lb plus P1020, delivered US Midwest.
