• Founded on 1 July 1975, Semimetais was then headquartered at Rua Santos Pousada, no. 706 in Porto.

On 27 November 1981, the same shareholders bought the company Bastos e Bastos, changing the company name to Sosemis, Lda, with headquarters at Rua da Rainha, no. 341 Fracção C in Vila Nova de Gaia, where the first cutting line was created.

On 31 December 1985, the company Senna Botto e Leitão (Porto Branch) was also acquired, with its name being changed to Novometais, Lda, with head office at Rua do Almada 33/35 1a frente, in Porto. This company was more geared towards selling to small-scale industry and the general public.

On 23/07/1992, 35% of the capital was sold to the German company Wieland Werke AG, the world’s leading company in the sector of copper and its by-products, such as brass.

On 18 December 1998, the company Semimetais became 100%-owned by the Wieland group.

On 28 March 2011 Semimetais became 100%-owned by the Stemcor group.

On 01 October 2014, Semimetais became a 100% locally-owned company, and as such, certified as an SME.
