Reliable joining and finishing of titanium: Vacuum-brazing, EB welding, Heat treatment, LMD. Lightweight construction & biocompatibility for aerospace & medical technology.
Titanium offers the highest specific strength, biocompatibility and excellent corrosion resistance. Listemann optimizes titanium components through Heat treatment, Vacuum-brazing and EB welding – ideal for aerospace structures, medical components and high-purity vacuum applications.
Heat treatment for microstructure control (α/β proportion, toughness, strength)
Vacuum-brazing with active/intermetallic solders; dense, resilient joining zones
EB welding for deep, narrow seams with minimal thermal influence
LMD structure for repair and function integration (e.g. wear zones)
Lightweight structures, housings, stators/rotor components
Medical technology: biocompatible assemblies and instruments
Vacuum & semiconductor technology: low-particle, low-warpage joins
Stress relief annealing to reduce distortion, solution annealing + ageing (depending on the alloy) for microstructure control (α/β proportion, toughness, strength).
Active solders such as Ag-Cu-Ti, Cu-Sn-Ti or Au-Ni-Ti (depending on the required operating temperature, strength and medium). Ti-/Zr-activated systems can also be used for hybrids (Ti-ceramic/glass).
Vacuum processes with very low residual gas pressures, activated solders (e.g. containing Ti), surfaces strictly clean of grease and oxide (grinding/fine blasting, degreasing), narrow gap (typically 0.02-0.08 mm) and defined heating/holding time.
Titanium absorbs oxygen/nitrogen quickly; vacuum prevents alpha-case and provides bright, reactive surfaces for dense joins.
Uniform gap of ~0.02-0.08 mm, defined solder feed points, fixation against component migration; avoid sharp edges, provide run-on/run-off radii.
Depending on the solder system: Ag-Cu-Ti rather medium temperatures, Au-/Ni-based active solders higher continuous and peak temperatures – selection according to load spectrum & medium.
Stress-relief annealing, gentle heating/cooling ramps, symmetrical fixing, minimal heat input (EBW) and uniform solder distribution.
Pure titanium and many Ti alloys are biocompatible; clean surfaces, process-reliable joining zone geometry and validated cleaning are crucial.
