A method for a workpiece comprising a material composed of a base material and an additive is disclosed, the method including spreading a granular material in superimposed layers. The granular material contains the base material and an organic binder. An ink contains a solvent for dissolving the binder, and a suspension of the additive. Using the ink, patterns are printed onto individual layers. The ink dissolves the binder in the region of the patterns, and introduces the additive in the region of the patterns. The patterns in the layers together produce a three-dimensional shape of the workpiece. The solvent is expelled so that the granular material is connected by the binder and the additive is fixed. Granular material unwetted by the solvent is removed to reveal the green compact of the workpiece. The green compact is thermally treated to convert the base material and the additive into the material.

A tungsten wire that contains tungsten or a tungsten alloy is provided. An average width of surface crystal grains in a direction perpendicular to an axis of the tungsten wire is at most 98 nm. The tungsten wire has a tensile strength of at least 3900 MPa. The tungsten wire has a diameter of at least 100 μm and at most 225 μm.

Proposed is a highly corrosion-resistant aluminum alloy including one or more components selected from among 0.1 wt. % or less (except for 0 wt. %) of Cu, 0.15 wt. % or less (except for 0 wt. %) of Si, 0.2 wt. % or less (except for 0 wt. %) of Fe, 0.9 to 1.5 wt. % of Mn, 0.03 to 0.15 wt. % of Ti, 0.03 to 0.15 wt. % of Cr, and 0.03 to 0.15 wt. % of Zr, and the remaining proportion of aluminum (Al) and unavoidable impurities.
