Aleris Develops New Plate Alloy
Cleveland-based Aleris has begun offering a new 7017 aluminum alloy in North America for commercial plate and defense end-uses. After extensive review and testing of Aleris 7017, the United States Army Research Lab has issued MIL-DTL-32505 for use in armor applications.
"7017 has a unique combination of properties making it ideal for the most advanced armor solutions," claims Lawrence Kramer, global defense field engineer at Aleris. "These include high strength, weldability and corrosion resistance. This alloy is currently utilized in Europe and Asia on combat vehicles to achieve superior ballistic protection."
The weld compatibility of the new alloy gives great flexibility to armored vehicle designers, enabling them to incorporate different design characteristics. The optimum balance of elements that comprise Aleris 7017 provides for superior stress-corrosion cracking resistance while maintaining high strength and weldability properties, the company claims.
