Frequently Asked Questions
Got more questions? We are happy to answer all your queries regarding custom titanium diaphragms and OEM production.
What titanium grades are available for custom diaphragms?
We support multiple grades tailored to your application's specific requirements:
- CP Grade 1 & 2: Utilized for optimal formability and high corrosion resistance.
- Grade 5 (Ti-6Al-4V): Recommended for applications demanding maximum tensile strength.
Our engineering team will assist in selecting the ideal grade for your target operating environment.
What thickness range can you support for acoustic vs sensor diaphragms?
We maintain strict micrometer-level dimensional tolerances across two primary ranges:
- Acoustic Applications (10–50µm): Ultra-thin foils for tweeters and micro-speakers to minimize moving mass and optimize high-frequency response.
- Sensor Applications (50–500µm): Thicker profiles for pressure sensors and transducers to handle higher stress differentials.
Can you manufacture custom dome geometries from customer drawings?
Yes. We specialize in custom forming based directly on your CAD specifications (STEP/IGES). We support:
- Complex dome profiles
- Specific suspension corrugation patterns
- Flat and custom-stamped geometries
Our precision stamping and proprietary tooling ensure exact geometric replication.
How does titanium compare to aluminum or beryllium diaphragms?
- Vs. Aluminum: Titanium offers a superior stiffness-to-mass ratio, pushing breakup modes to significantly higher frequencies.
- Vs. Beryllium: While beryllium is stiffer, titanium is far more robust, non-brittle, non-toxic to manufacture, and significantly more cost-effective for large-scale OEM production.
How do you control acoustic consistency from prototype to mass production?
We achieve strict batch-to-batch repeatability through a rigorous manufacturing process:
- Material Integrity: Controlling the titanium's internal grain structure during the rolling phase.
- Precision Tooling: Utilizing high-precision progressive tooling for exact stamping replication.
- Rigorous QA: Extensive dimensional and mechanical testing guarantees that mass-produced units perfectly match your golden prototype's acoustic parameters.
Are your diaphragms suitable for harsh or high-temperature environments?
Yes. Titanium is inherently suited for harsh industrial applications:
- Chemical Resistance: Exceptional durability against saltwater, industrial chemicals, and biological fluids.
- Thermal Stability: Maintains structural and performance stability at elevated temperatures far better than aluminum or polymer alternatives.
What information is required to request a custom quote?
For a faster Design for Manufacturability (DFM) review and accurate pricing, please provide:
- CAD (STEP/IGES) or PDF drawings
- Desired dimensions, thickness, and required tolerances
- Preferred material grade
- Estimated OEM volume and application target
What are your typical lead times for custom projects?
Lead times vary based on design complexity, tooling requirements, and volume:
- Rapid Prototyping: We support accelerated R&D cycles to get your designs tested faster.

Precision Titanium Diaphragms: A Selection Guide
In demanding applications ranging from high-fidelity audio to precision sensors and critical medical devices, diaphragm performance is paramount. As a specialized manufacturer, Hele Titanium engineers premium diaphragm solutions focused on acoustic fidelity, sensor accuracy, and long-term durability.
This guide outlines the critical engineering considerations, material comparisons, and manufacturing processes required to specify the optimal titanium diaphragm for your project.
Before You Specify a Titanium Diaphragm, Confirm These 3 Things:
- Target application and performance objective?
- Required material grade, thickness, and geometry?
- Prototype quantity or scalable OEM volume?
1. Material Properties & Grade Selection
Diaphragm performance heavily depends on the interplay between stiffness, mass, fatigue resistance, and corrosion resistance. Selecting the right titanium grade is the foundational step.
CP Grade 1
Maximum formability and deep drawing capability.
- Highest ductility
- Excellent corrosion resistance
- Ideal for complex dome shapes
CP Grade 2
The industry standard balancing strength and formability.
- Higher yield strength than Gr 1
- Good fatigue life
- Standard for most acoustic applications
Grade 5 (Ti-6Al-4V)
Alloyed for maximum tensile strength and stiffness.
- Highest stiffness-to-weight ratio
- Lower formability
- Used in extreme pressure sensors
2. Comparative Analysis of Diaphragm Materials
| Material | Key Advantage | Key Limitation | Relative Stiffness | Relative Density | Typical Sound Characteristic |
|---|---|---|---|---|---|
| Titanium | High stiffness/mass, very durable | Moderate internal damping | High | Medium | Fast transients, bright, precise |
| Beryllium | Ultimate stiffness-to-mass ratio | Brittle, toxic dust, very high cost | Very High | Low | Ultra-detailed, extended HF |
| Aluminum | Lightweight, cost-effective | Lower fatigue life than Ti | Medium | Low | Clean, slightly softer than Ti |
| Graphene | Incredible strength, low mass | Difficult to scale/manufacture | High | Very Low | Highly linear, low distortion |
| Paper / Cellulose | Excellent internal damping | Sensitive to humidity, lower stiffness | Low | Low | Warm, natural, smooth |
| Silk / PET | Smooth response, easy to form | Lacks rigidity for extreme HF | Very Low | Low | Soft, non-fatiguing |
3. Engineering Considerations for Audio Applications
Titanium is the material of choice for premium tweeters, compression drivers, and high-resolution headphones due to its ability to move air rapidly without deforming. The engineering focus must be on managing break-up modes.
- Transient Response: Low mass enables rapid acceleration and deceleration.
- Break-up Mode Control: Stiffness pushes resonant frequencies beyond the audible spectrum.
- Custom Geometry: Domes and corrugations are engineered to add structural rigidity without adding mass.
4. Industrial, Sensor & Medical Applications
Beyond audio, titanium diaphragms serve as critical barriers and sensing elements in harsh environments.
Precision Sensors
Provides linear deflection under pressure while resisting corrosive industrial gases.
Medical Devices
Biocompatible membranes used in fluid delivery and ultrasonic surgical tools.
5. Manufacturing & Forming Processes
Achieving micrometer-level precision requires advanced manufacturing techniques:
- Precision Foil Forming & Stamping: Used for high-volume dome production, requiring specialized tooling to manage titanium's spring-back effect.
- Hydroforming: Utilizes fluid pressure to form complex geometries with uniform thickness distribution.
- Chemical Etching: Employed for ultra-thin sensor diaphragms where mechanical stamping would induce stress.
- Trimming & Finishing: Laser or precision mechanical trimming ensures clean edges, vital for acoustic suspension and assembly.
