The technology was originally discovered by Alcan international-now Rio Tinto alcan-and Norsk Hydro of Norway, while developing wear-resistant aluminum products.
“In early 2000, Cymat licensed the technology from Alcan and bought the patents outright from Norsk Hydro to really productionize it to where it is today, ” says Tim Hardman, Cymat’s president.
It also had its eye on Alcan, a big French-Canadian aluminum operator, but was outbid last year by Rio Tinto.
Cymat公司董事長TimHardman説：“ 2000年早期，Cymat公司從Alcan公司分離出來，買斷了NorskHydro公司的專利後才能真正生產出現在這樣產品。”
Rio's offer for Riversdale is its first attempt at a sizeable acquisition since a disastrous purchase of Alcan in 2007.
Alcan is a handy asset-the vast amounts of energy required to smelt aluminium are supplied by reliable, cheap hydroelectricity.
