Magnesium has the unique feature of being the lightest in practical metals, but its utilizing range was limited due to difficulties. Japan needs to push the limits of magnesium and expand its potential using her technological power. MACRW applies the skills of craftsmen to try to spread the charm of magnesium by producing familiar products with it. When the company was founded in 2010, it was given an unusual name, MACRW, an acronym for Magnesium Alloy Cold Rolling Woks. The company’s business domain is to use magnesium alloy as a material and take on the challenge of cold working, which is uncommon for magnesium. The name also alludes to another meaning; that there is a way to win, with “the last turn of foot” in horse racing. The dream is that material magnesium might take a long time to gain traction, but would eventually spread all at once, changing the world.
