The Washington Post is reporting that the company making the aluminum-rich, 1-in-4-inch (6.6-centimeter) AstroAluminum is moving away from the material, citing declining sales.
AstroAluminum did not immediately respond to a request for comment from Ars.
The company previously sold the material to other companies, but it has since sold its product line to a third party.
The Astro Aluminum company made 1.2 million aluminum anchors in 2017, according to company filings.
“We will continue to make our anchors as they are made and will continue with our continued investment in the manufacturing of the Astro aluminum anchor and other products,” AstroAluminum said in a statement.
The company is making the new aluminum anchors at its facility in Virginia, where it has about 400 employees.
The firm said it would not comment on whether it would reduce staffing.
Astro Alum is made from a combination of aluminum and carbon steel, and it has an anchor strength of around 1,200 pounds per square inch.
“Our focus has always been on providing a high-quality product for our customers, and we’re confident we can deliver that,” said Jim Schumann, AstroAlum’s chairman and CEO, in a press release.
“Our industry is facing a significant economic and social impact from the collapse in the aluminum market.
Our commitment to the Astrodome and the preservation of the facility will continue.”
The Astro company is also investing in a new aluminum-manufacturing facility in Georgia, and is expected to begin producing the material in 2019, according the release.
The announcement comes on the heels of an announcement last year that the U.S. was on track to produce 1.5 million aluminum anchor anchors by 2020.
