High-Magnesium Aluminum Alloy Group Seeks Individuals to Participate in Seawater Exposure Program

A task group of ASTM Subcommittee G01.09 on Corrosion in Natural Waters is conducting a Seawater Exposure Program for High-Magnesium Aluminum Alloys used in marine vessels and structures. Part of Committee G01 on Corrosion of Metals, the subcommittee seeks participation from the aluminum and ship-building industries, marine classification societies, naval architecture and marine engineering firms, and marine regulatory agencies.

The group initiated the program in response to requests, from Aluminum Association International and ASTM Subcommittee B07.03 on Aluminum Alloy Wrought Products, for corrosion information on aluminum sheet products in alloys such as 5083, 5086, and 5456 in currently produced tempers in natural environments.

Task-group chairman Jack Snodgrass encourages individuals to participate. “Meetings will commence shortly using the virtual meeting format,” he says. “Subcommittee B07.03 will use the results in the ongoing evolution of new B 928, Standard Specification for High Magnesium Aluminum-Alloy Sheet and Plate for Marine Service” [not approved at press time].

Interested parties should contact Snodgrass at Alcoa, New Kensington, Pa. (phone: 724/337-2313) or Committee G01 manager Len Morrissey, Jr., ASTM International (phone: 610/832-9719). ASTM Committee G01 meets Nov. 19-21 in Tampa, Fla. Contact Morrissey for membership or meeting details.

ASTM Committee B07 on Light Metals and Alloys meets Nov. 17-19 in Tampa. For meeting or membership details, contact B07 manager Dan Schultz, ASTM International (phone: 610/832-9716). //
