Chemical Strengthening D263 Thin Glass: D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um); CS > 600 MPa, DoL 8 – 40 um. Single-piece prototypes to production volumes, quoted from your drawing.
Specify chemical strengthening d263 thin glass when the bare substrate falls short: potassium ion exchange, processed by KNO3 salt bath, 380 – 450 C, brings D263 Thin Glass to CS > 600 MPa, DoL 8 – 40 um.

Beyond this page, D263 Thin Glass routinely runs through cnc machining, polishing, laser cutting, etching in our shop – most real parts combine two or three of these steps.
DFM notes from the shop floor
The shop-floor rules that matter here:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- Sequence matters: all machining happens before chemical strengthening; post-coating rework is not economical.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
The full rules live in our tolerance design guide and holes and edges design guide.

Common questions
How does D263 Thin Glass behave under heat?
CTE is 7.2 x 10^-6 /K and continuous service reaches 400 C (Tg 557 C), which is what drives its use where down-drawn fire-polished surfaces matters.
What does chemical strengthening add?
4 – 8x bend strength on thin covers. Applied by KNO3 salt bath, 380 – 450 C to CS > 600 MPa, DoL 8 – 40 um.
Is there a minimum order for chemical strengthening d263 thin glass?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
