About AMAC Manufacturing

We have a new name, and the same AMAC you know.

Since 30 June 2026, our Kilsyth business has operated as AMAC Manufacturing. Same factory, same team, same Australian-made quality, and ISO 9001 certified since 1997.

We have been making metals and alloys here in Melbourne since 1974, and we are only getting started. We are investing in new software and systems, growing the team and taking on new kinds of projects.

AMAC Corrosion and AMAC Alloys continue as the names you know.

Our story

Continuing a proud legacy

AMAC began in 1974 as The August Metal and Alloy Company, making metals and alloys in Melbourne. It has been Australian made ever since.

The business now continues under the ownership of Mark Rigg, who has been part of AMAC for almost 30 years.

“David and Hilary Whitby built AMAC on quality, integrity and looking after customers. I’m honoured to carry that on. The people, the factory and the standards stay the same.”
