Yeah but please don't cherrypick your archeological ages. Coastal regions of Finland were influenced by the Scandinavian Bronze Age culture, but in inland Finland, the Bronze Age was initiated by the Seima-Turbino phenomenon. The bronze used in Seima-Turbino objects was derived from the Sayano-Altai mountains (https://pureadmin.qub.ac.uk/ws/files...PDF_HI0001.pdf):
Comparative analysis of metal objects in various archaeological sites allowed attributing considerable part of complexes of Middle and Lower Volga region, Southern Urals and Trans-Urals to the "Seima chronological horizon" including Srubnaya and Abashevo Cultures (Chernykh 1970, Figure 67). The major concentration of the ST type objects has been found in the Volga-Ural region. The Abashevo sites either preceded or coexisted with the "Seima chronological horizon" (third quarter of the 2nd mil. BC, ibid, p. 103). However, the thin-wall-casting technology of the ST type bronze objects makes their principle difference from rather rough Abashevo (or "common Eurasian" by Chernykh 1970) casting and the later forging technology, which does not allow considering South Urals and Cis-Urals as the area of production of these items. The spectrum analysis of the ST bronze objects suggests Sayano-Altai Mountains as a region of provenance of raw materials (tin bronze) used. Therefore, until recently, it has been assumed that western foothills of Sayano-Altai Mountains were the place of origin of the ST transcultural phenomenon (Chernykh 1970). However, the increasing number of ST finds in Western Siberia and Central Asia allows expanding the presumable place of the initial impulse onto eastern and south-eastern foothills of Altai (Chernykh 2015).
Seima-Turbino objects have been found even in Northern Ostrobothnia:
