Title: Andrew Josef Widawski Ogilvy: Innovator in Brazing Technology

Introduction

Andrew Josef Widawski Ogilvy is a notable inventor based in Port Talbot, Great Britain. He holds two patents that highlight his innovative contributions to the field of materials engineering, particularly in brazing technologies which are essential in various manufacturing processes.

Latest Patents

One of Ogilvy's latest patents is for a self-fluxing brazing piece. This invention involves a composite material that consists of at least one inorganic material embedded in a metal or metal alloy matrix. During brazing, the inorganic material acts as a flux, facilitating the development of a thermally induced metallic bond. Notably, this matrix can be an aluminum silicon brazing alloy, and the inorganic material may include potassium-fluoro-aluminate flux. The brazing piece is produced using a spray forming technique, showcasing innovative methods in material application.

Ogilvy also holds a patent related to silicon alloys for electronic packaging. This method involves melting a silicon alloy that contains more than 50 wt. % silicon, often incorporating aluminum. The molten alloy undergoes inert gas atomization, yielding either powder or a deposit created by spray forming. This process results in a material where silicon forms a continuous phase characterized by fine, randomly oriented crystals. Such silicon-based alloys, particularly comprising 70 wt. % silicon and 30 wt. % aluminum, serve as valuable engineering materials suitable for electronics packaging due to their machinability.
