Titanium Tweeter Domes
Specify: Drawing/sample · Diameter · Dome height · Thickness · Edge
Dome components reviewed against the controlled geometry, material, surface, edge and OEM assembly interface.
Audio · Sensor · Pressure · Drawing-Based Components
Custom Titanium Diaphragms for Audio, Sensor & Industrial OEMs
Define the diaphragm role, controlled drawing or sample, titanium Grade, thickness, profile, interface, tooling, inspection, application validation and quantity before comparing quotations.
Component roleAudio, sensor, pressure or industrial
Material basisGrade, specification, condition and thickness
Geometry & interfaceProfile, corrugation, edge and joining
Acceptance boundaryComponent inspection versus assembly validation
Before requesting a quote: identify the actual diaphragm function and whether HELE supplies a formed component, a joined subassembly or another defined scope. Audio response, sensor accuracy, pressure safety and medical-device compliance cannot be inferred from material Grade alone.

Forming Done In Our Own Plant
Titanium diaphragms are deep-drawn, trimmed and inspected in our own plant on tooling we design and build ourselves. We are a titanium mill first, so the strip a dome is drawn from is rolled and certified by the same group — the material condition that decides whether a thin dome draws without splitting is not something we have to ask a supplier about.
- Forming routes
- Deep drawing for domes and formed diaphragms, with hydroforming, stamping and spinning available for geometries that suit them.
- Tooling
- Designed and built in-house. Simple dome tooling typically 10–15 days from frozen drawing; multi-stage or corrugated tooling is quoted per part.
- Grades
- Commercially pure titanium for formability-driven components; higher-strength grades where the load case requires them. The grade and condition are fixed for your part at Definition Review, not assumed.
- Inspection
- Thickness and formed-profile measurement, coordinate measuring machine, digital measuring microscope, XRF grade verification on incoming strip.
- Thickness, diameter and draw ratio
- Quoted against your drawing or approved sample. We do not publish a universal forming envelope, because the achievable combination of thickness, diameter and draw depth is a trade-off, not three independent limits — a thin dome at a large diameter and a deep draw are not simultaneously available, and a published range implying otherwise would be misleading.
What we do not do
Assembled acoustic, fatigue, pressure-cycle or regulatory testing. Those are validated by the OEM or an agreed test house against the plan frozen at Definition Review. We inspect the component; we do not approve the system.
Material & Standards Map
Do Not Turn a Raw-Material Standard into Finished-Component Approval
| Reference or control | What it can cover | What still requires order-specific definition |
|---|---|---|
| ASTM B265 | Titanium and titanium-alloy strip, sheet and plate within the ordered scope and revision. | Formed profile, thickness distribution, edges, interface, joining, component inspection and functional validation. |
| ASME B40.100 | Pressure gauges and gauge attachments, including diaphragm-seal requirements within its scope. | It does not automatically govern audio, sensor, pump, valve or other industrial diaphragms. |
| ASTM F67 / ISO 5832-2 | Unalloyed titanium material used for surgical-implant manufacture within each standard's scope. | Finished-device design, forming validation, biocompatibility, sterilization and regulatory approval. |
| Customer drawing / sample plan | The component geometry, interface, inspection and acceptance criteria agreed for the order. | Complete assembly performance unless explicitly included and tested. |
Process Review
From Controlled Input to Approved Batch
The actual forming and trimming route is selected only after material, thickness, geometry, tooling, quantity and acceptance are reviewed.
01
Definition Review
Freeze role, files, revision, material, geometry, interfaces, load cases and validation owner.
02
Tooling & Route
Confirm blank, forming, trimming, edge, cleaning, joining and controlled external operations.
03
Prototype Approval
Inspect the component and, where required, validate the assembly against an approved test plan.
04
Batch & Change Control
Link material, tooling, settings, inspection, golden sample, deviations and release documents.

Freeze the Component and Validation Boundary
Align component role, product definition, material, thickness, profile, interface, tooling, prototype, component inspection, system validation, traceability, change control and commercial scope before order release.
- ✓ State whether a drawing, model or golden sample controls.
- ✓ Define thickness and profile after forming—not only raw stock.
- ✓ Match inspection methods to thin, flexible geometry.
- ✓ Assign acoustic, sensor, pressure, leak, cycle and regulatory validation responsibility.
Do not release the PO with only:
- “Grade 1 precision diaphragm”
- A visual sample with no measurable profile
- Raw thickness with no post-forming criterion
- A material certificate as the only acceptance evidence
- An assembly performance claim with no defined test owner
FAQ
Titanium Diaphragm Purchasing Questions
What information is needed for a titanium diaphragm quotation?
Provide the diaphragm role, controlled drawing or approved sample, titanium Grade or UNS and material specification, thickness, diameter, formed profile or corrugation, interface and edge details, quantity, tooling status, inspection, validation responsibility, documentation and packing.
Can an approved sample replace a drawing?
A sample can support comparison or reverse-engineering review, but it should not silently become the full acceptance standard. Define which dimensions, profile, material, surface and performance characteristics the sample controls, how it is measured and how the master sample is preserved.
Is Grade 1, Grade 2 or Grade 5 always best for a diaphragm?
No. Selection depends on the material specification, thickness availability, forming route, strength, stiffness, fatigue or cycle duty, corrosion environment, joining route and qualified assembly performance. Confirm the exact Grade and condition for the order.
Does a titanium dome guarantee a target frequency response?
No. Acoustic performance is an assembly result influenced by dome and surround geometry, thickness distribution, edge condition, adhesive or joint, voice coil, motor, enclosure and test method. Component inspection and assembled transducer testing are separate controls.
What must be defined for a pressure or sensor diaphragm?
State media, pressure differential and direction, normal/overpressure/vacuum cases, temperature, cycle profile, active diameter, supports, interface or weld, displacement or sensitivity target, proof/burst/leak requirements and validation responsibility.
Does ASTM B265 material compliance approve the finished diaphragm?
No. ASTM B265 applies to titanium and titanium-alloy strip, sheet and plate within its scope. Finished diaphragm conformity still depends on the approved geometry, forming, trimming, joining, inspection and application-specific validation.
