Karhuvalu Oy, founded in the Pori region in 1947 and later transferred its operations to Rauma, initially only lit copper and aluminum alloys, until in the 1980s production was expanded to include stainless and acid-resistant steels and cast irons. In 2003, the company's business was transferred to new owners. At the same time, the company changed its name to Karhuvalu Oy and Mika Koivuniemi became the new CEO. In 2004, the company's business moved from Pori to Rauma to new and appropriate premises.
