An object of the invention is to provide: an alloy article that has excellent homogeneity in the alloy composition and microstructure as well as significant shape controllability, using an HEA with significant mechanical strength and high corrosion resistance; a method for manufacturing the alloy article; and a product using the alloy article. There is provided an alloy article comprising: Co, Cr, Fe, Ni, and Ti elements, each element in content of 5 to 35 atomic %; more than 0 atomic % to 8 atomic % of Mo %; and remainder substances of unavoidable impurities. And, ultrafine particles with an average diameter of 40 nm or less are dispersedly precipitated in matrix phase crystals of the alloy article.
