Titanium Ring
Forged and rolled titanium rings — supplied as ring blanks with stock for machining, or finish machined to your drawing for flanges, seal rings, spacers and annular casings.
Blank, or finish machined. Send the drawing. Ring stock and final machining are quoted against the same datum, so the allowance is deliberate. Ask about rings
Definition
Why a ring blank beats a solid disc
Starting from a ring instead of a solid disc removes most of the material you would otherwise pay for and machine away, and it aligns the grain flow with the hoop direction. For flanges, seal rings, spacers and annular casings that is both cheaper and metallurgically better.
Rings are produced by open-die forging or ring rolling from billet, then supplied either as a blank with machining stock, or rough machined, or finish machined to your drawing by Baoji Tuohang under ISO 9001.
Ti-6Al-4V (TC4 / GR5) is the usual choice; commercially pure GR2 is used where corrosion resistance matters more than strength; Ti-6242 is available where the ring runs hot.

QualityFAQ
Common questions
Can you supply the ring already finish machined?
Yes. Rings are regularly supplied finish machined to drawing by the machining side of the group under ISO 9001, with a dimensional report. Tell us whether you want a blank, a rough machined ring or a finished part.
Can I buy the material without machining?
Yes. Material is routinely supplied as certified mill product with no machining. Machining is a separate scope, quoted only if you ask for it.
Who actually produces the material?
The mill product is produced by Baoji Qicheng Nonferrous Metals Co., Ltd., the raw-material company upstream of the same group, in Baoji. Machining and inspection, where quoted, are carried out by Baoji Tuohang Precision Manufacturing Co., Ltd. Two legal entities, one group — and one accountable party for what you receive.
What is the lead time?
It depends on the grade, the size and whether the item is held in stock or has to be produced. We state a date on the quotation rather than quoting a nominal lead time up front.
