Invitation to ICAA18

Welcome to ICAA18! We are very grateful for the opportunity to host the 3rd ICAA in Japan. The conference is organized by the Japan Institute of Light Metals (JILM), which is a world-renowned academic society specializing in light metals and will celebrate its 70th anniversary in 2021. We aim to organize ICAA18 taking into account the Covid-19 situation with the help of participants from all over the world.  ​

Aluminium and its alloys have been utilized for both structural and functional applications. In addition, we need to focus on their excellent potential as an eco-friendly material. The use of light aluminium alloys in automotives is an effective way to reduce the emission of CO2 while driving. We can produce recycled aluminium ingots with substantially smaller fabrication energy and a lower greenhouse gas emission rate, compared to that of the virgin aluminium.  ​

The active use of recycled aluminium should be recommended for global environmental protection. Now is our opportunity to make use of the results of both basic and applied research studies of aluminium and its alloys so that we can achieve a sustainable society. “Aluminium and its alloys for zero carbon society” is the main theme of ICAA18. We hope that ICAA18 will allow participants from all over the world to get to know and inspire each other, and to encourage young researchers and students who will lead the future of aluminium.  ​

We look forward to your attendance at ICAA18 in Toyama, Japan! ​

I am honored to announce that the 18th International Conference on Aluminium Alloys (ICAA18) will be held from 4th to 8th of September, 2022 in Toyama, Japan.​
Thanks to abundant and clean water, an inexpensive, stable power supply, fewer natural disasters, and convenient transportation, Toyama has developed as one of the leading manufacturing prefectures and it has various industries such as metals, machinery, pharmaceuticals, chemicals, textiles and IT. And the aluminium industry in Toyama has evolved based on Takaoka copperware casting technology and stable power supply. Toyama has become the site of the leading aluminium industry in Japan and a global fastener manufacturer. Toyama also has a variety of natural rich terrain from the 1,000 meters depth of Toyama Bay to the 3,000 meters crest of Tateyama Mountains in the northern Alps. It is characterized by a vast forest area, one of the country's leading hydropower and geothermal resources, and a high potential for renewable energy.​
Toyama also supports Sustainable Development Goals (SDGs) and as one of its plans for environmentally-friendly future, it has a strategy to create a Compact City by restructuring public transportation.​
Please come and see eco-friendly, Amazing Toyama. ​
