Titanium Forgings

May 6, 2024 by EST-Metal 0 Comments

Titanium Blocks: Precision and Versatility

Titanium blocks are available in a diverse range of thicknesses and widths, offering unparalleled versatility in various applications. Unlike other metals that are easily cast and formed, titanium, owing to its reactivity, requires meticulous handling within an inert environment. Exposure to the atmosphere can render titanium brittle and compromise its integrity.

Advancements in Fabrication:

In recent years, significant strides have been made in tooling to streamline fabrication processes. Innovations such as enhanced welding techniques, improved torch cups for superior gas coverage, and specialized tools for purging spool assemblies have revolutionized the fabrication of titanium. Machining capabilities continue to evolve, with manufacturers constantly pushing the boundaries to develop robust machinery tailored for titanium applications.

Standard Specifications and Grades:

Titanium blocks adhere to stringent standards to meet diverse industry requirements. Common specifications include ASTM B348, ASTM B381 for general applications, and AMS 4928 for aerospace applications. Titanium is available in various grades, ranging from Grade 1 to Grade 12, each offering unique properties suited for specific applications. Notable grades include Grade 5 (Ti-6AL-4V), Grade 7 (Ti-0.2pd), and Grade 9 (Ti-3AL-2.5V), among others.

Available Sizes

Size Range Dimensions (Diameter x Height)
Small Dia 150-300mm x 20-600mm
Medium Dia 300mm-500mm x 20-600mm
Large Dia 500-1100mm x 35-600mm

 

Titanium boasts exceptional properties that make it an ideal choice for a myriad of applications. Its corrosion resistance, lightweight nature, and high hardness set it apart from conventional materials. Beyond industrial uses, titanium finds its way into architectural marvels, decorative elements for ceilings and walls, and various ornamental applications, driving the need for advanced surface treatments.
 

Surface Treatment Techniques

  • Annealing and Pickling: Pickling with buddha acid hydrogen yields a lustrous silver finish, albeit at a low cost. However, indiscriminate disposal of pickling by-products poses environmental challenges.
  • Vacuum Annealing: Vacuum annealing ensures the titanium remains smooth and pristine post-cold rolling, imparting a subtle silver hue with a touch of grey gloss.
  • Blasting: High-pressure blasting with glass beads, metal balls, or sand achieves a matte finish, ideal for decorative purposes.
  • Embossing: Mechanical or erosive techniques create intricate designs on the titanium surface, adding a distinctive aesthetic appeal.
  • Etching: Electric etching or chemical etching methods are employed to engrave logos or text onto titanium surfaces, offering branding opportunities.
  • Mirror Finishing: Achieving a mirror finish on titanium poses challenges due to its inherent affinity to other materials, requiring specialized techniques for pristine results.
