Title: Anthony J. Bryant and His Aluminum Alloy Patents.

Introduction

Anthony J. Bryant is an inventor associated with Banbury, Great Britain, and Alcan International Limited. His patent work includes innovations in aluminum-magnesium-silicon (Al-Mg-Si) extrusion alloys. The supplied information lists 3 patents for Bryant.

Latest Patents

Two of Bryant’s listed patent titles are “Al-Mg-Si Extrusion Alloy” and “Al-Mg-Si Extrusion Alloy and Method.” Both describe an extrusion ingot in which substantially all magnesium is present as particles of beta-prime-phase magnesium silicide (Mg₂Si), with an average particle diameter of at least 0.1 microns and substantially no beta-phase Mg₂Si.

The described production method involves casting and homogenizing the alloy ingot, cooling it to a holding temperature between 250°C and 425°C at a rate of at least 400°C per hour, holding it for 0.25 to 3 hours, and then cooling it further. The patents state that this approach produces ingots with improved extrusion properties.
