Wire that saves lives — every day, invisibly.
Fine wire is the invisible material of modern medical technology — from catheter to bracket.
- Fine stainless wire from approx. 0.020 mm — within the group down to 11 µm.
- Typical materials: 304V (1.4301, vacuum re-melted), 316L (1.4404/1.4435) — grade selected per application.
- Applications: diagnostic & interventional catheters, stents, surgical instruments, dental technology.
- Purity and traceability through multiple/vacuum re-melted grades, best surfaces, documented batches.
In medical technology, every detail counts. A catheter is guided from the leg vein to the heart to examine coronary vessels. A bracket in orthodontics stands under permanent tension and must not break. In all these cases the decisive material is the same one — and invisible to the patient: fine wire. The BenderWire Group manufactures it where tolerances lie in the micrometre range and material purity decides function and safety.
Where medical wire works.
Catheters (diagnostic & interventional)
Fine wires from 0.05–0.07 mm are braided and coated with plastic — without direct tissue contact. This creates catheters that can be guided minimally invasively to the heart or brain. Within the group, the Stamm fine wire plant supplies specialised catheter manufacturers across Europe.
Stents & implant-related components
The highest demands on purity, surface and biocompatibility — met through carefully selected, multiple re-melted stainless grades.
Surgical instruments
Stainless steel wire with defined strengths and the finest surfaces — cleanable, sterilisable, dimensionally stable.
Dental technology
Spring-hard wire for brackets that must not break under orthodontic tension; fine wire for root canal instruments.
Alloy is not everything — the process matters too.
Mostly austenitic stainless steels are used for medical applications — such as 304V (1.4301, vacuum re-melted) or the molybdenum-alloyed grades 316L (1.4404 / 1.4435). Which grade is right depends on corrosion exposure, strength and purity, and is defined together with the customer. What matters is not just the alloy, but the process: multiple and vacuum re-melted grades reduce inclusions, improve the surface and create reproducibility. Every delivery is traceable through documented batches.
What sets us apart in medical wire.
Fineness down to 11 µm
Within the group we manufacture fine wire down to 11 µm — reproducibly.
Verifiability
Critical dimensions are proven metrologically and documented.
From sample to series
Sampling, approval, series production — from a single source.
Future materials
We are pursuing nitinol and other future materials as a development and partnership direction.
Frequently asked questions.
Which stainless steel is used for medical wire?
Predominantly austenitic grades such as 304V (1.4301) and 316L (1.4404/1.4435), depending on requirements for corrosion, strength and purity; often vacuum re-melted.
How thin can medical wire be manufactured?
Medical wire from approx. 0.020 mm; within the group dimensions down to 11 µm are possible.
Are catheter wires manufactured?
Yes — fine wires from 0.05–0.07 mm, braided and coated with plastic, for diagnostic and interventional catheters.
Is the wire traceable?
Yes, through documented batches; production is carried out to customer specification.
Do you supply samples and small quantities?
Yes, from sampling through to series production.
