Metal Fabrication & Engineering

We have honed our skills working with advanced metals, sometimes called exotic metals and our team has proven experience in helping to design systems for unique applications.

Titanium

  • Titanium is the fourth most plentiful metal on earth; Australian rutile ore (TiO2)
  • Titanium is half as dense as steel - 0.163 lbs./cu. in.
  • Similar in strength to 316 SS - 50ksi Min. UTS
  • Excellent corrosion resistance, especially C1’s
  • Suitable Environments:
    • Wet Chlorine
    • Chlorinated Compounds
    • Oxidizing Acid
    • Sea Water
