Working with ERTi-1
Is ERTi-1 easy to machine?
Soft and gummy — sharp, positive-rake carbide tools, low speed with heavy flood coolant to avoid galling, smearing and fire risk from fine chips.
Can ERTi-1 be welded?
GTAW/GMAW/PAW with 99.995 % argon or Ar-He, trailing shield and full back purge; keep interpass <150 °C and weld area free of oil, moisture and iron pickup — a silver/straw weld colour is acceptable, blue/grey is reject.
Can ERTi-1 be formed, bent or molded?
Wire draws and bends readily; deposited metal is the most formable CP Ti — cold-form generously but allow high springback and avoid iron-contaminating tooling.
ERTi-1 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on ERTi-1?
Pickle in HNO3/HF to remove alpha case and iron smear, then colour-anodize or leave bare; do not shot-blast with steel media.
Surface treatments FabDigit runs on titanium parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

ERTi-1 — frequently asked
What is ERTi-1 used for?
ERTi-1 is typically used for welding CP Ti Grade 1 tanks, chemical processing equipment, deep-drawn titanium components and corrosion-resistant piping. In short: purest CP titanium filler; maximum weld-metal ductility; matches Grade 1 base metal.
What is the yield strength of ERTi-1?
ERTi-1 has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 99% of titanium grades. Strength varies by condition: see the 2 listed tempers.
Is ERTi-1 easy to machine?
Not especially — machinability is rated fair (40/100, better than 93% of titanium grades). Soft and gummy — sharp, positive-rake carbide tools, low speed with heavy flood coolant to avoid galling, smearing and fire risk from fine chips.
Can ERTi-1 be welded?
Yes — weldability is rated excellent (95/100). GTAW/GMAW/PAW with 99.995 % argon or Ar-He, trailing shield and full back purge; keep interpass <150 °C and weld area free of oil, moisture and iron pickup — a silver/straw weld colour is acceptable, blue/grey is reject.
What surface finishes work on ERTi-1?
Pickle in HNO3/HF to remove alpha case and iron smear, then colour-anodize or leave bare; do not shot-blast with steel media.
Can ERTi-1 be formed, bent or molded?
Wire draws and bends readily; deposited metal is the most formable CP Ti — cold-form generously but allow high springback and avoid iron-contaminating tooling.
What is the maximum service temperature of ERTi-1?
ERTi-1 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERTi-1-AW and ERTi-1 AW-SR?
AW is the default condition — default reference condition: properties of the undiluted GTAW deposit made with full inert-gas shielding. AW-SR: use for weldments needing residual-stress reduction before machining or for SCC-sensitive chemical service; strength drops slightly, ductility recovers. Yield strength is 210 MPa in AW versus 195 MPa in AW-SR.
How much does ERTi-1 cost?
ERTi-1 is a high-cost titanium ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
