Titanium Sheet Metal: Properties and Common Uses
In this blog, we’ll break down the properties, applications, and advantages of oxygen-free copper, helping you understand why it’s preferred over standard copper in various industries.
Titanium Sheet Metal: Properties and Common Uses
Titanium sheet metal earns its place in demanding industries by combining low weight with strength and near-total corrosion resistance. Understanding its core properties makes it easier to see where it’s the right call — and where a cheaper metal would do.
Key properties
- Low density: roughly half the weight of steel, easing handling and lowering finished-part weight.
- Corrosion resistance: a self-healing oxide layer resists seawater, chlorides, and many acids.
- Strength: Grade 2 sheet is moderately strong; Grade 5 sheet is dramatically stronger.
- Biocompatibility: non-reactive with body tissue, making it a medical staple.
- Heat tolerance: holds strength where aluminium softens.
Common uses
Titanium sheet is fabricated into aircraft skins and brackets (why titanium suits aerospace), surgical trays and implant housings, marine panels and heat exchangers, and chemical-plant linings where corrosion would destroy ordinary steel.
Fabrication notes
Grade 2 sheet forms and welds readily; Grade 5 needs more care. Whatever the grade, work with sharp tooling and avoid contamination during welding. For sizing and ordering details, see titanium sheet sizes and specifications.
FAQ
Does titanium sheet rust? No — it forms a protective oxide layer instead of rusting.
Is titanium sheet hard to weld? Grade 2 welds well; all titanium welding needs shielding to prevent contamination.

Do you have any questions?
A: Carbon steel relies on carbon content alone for its properties. Alloy steel adds elements like chromium, nickel, molybdenum, and vanadium to achieve specific improvements — higher strength, better low-temperature toughness, creep resistance, or corrosion resistance — giving it a far broader performance range than carbon steel.
A: For ambient to 400°C service, ASTM A516 Grade 70 is the standard choice. For high-temperature refinery or power plant use (up to 600°C), ASTM A387 Grade 11 or 22 (chrome-moly) applies. For cryogenic service down to -196°C, 9% nickel steel (ASTM A553) is required.
A: Wear-resistant grades like AR400/AR500 are quenched to martensitic hardness of 370–500 HB — 3–4× harder than structural grades like A572-50. They resist abrasive wear in mining and construction equipment but have limited weldability and are not suitable as primary structural members.
A: CE (= C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15) predicts susceptibility to hydrogen-induced cold cracking during welding. Sheets with CE above ~0.40 require preheating to slow cooling and allow hydrogen diffusion, preventing weld cracking. Always develop a qualified WPS based on the specific CE value.
